 # Overview
-mxisd is a Federated Matrix Identity server for self-hosted Matrix infrastructures.
+mxisd is a Federated Matrix Identity server for self-hosted Matrix infrastructures with enhanced features.
   
-mxisd uses a cascading lookup model which performs lookup from a more authoritative to a less authoritative source, usually doing:
-- Local identity stores: LDAP, etc.
-- Federated identity stores: another Identity Server in charge of a specific domain, if applicable
-- Configured identity stores: another Identity Server specifically configured, if part of some sort of group trust
-- Root identity store: vector.im/matrix.org central Identity Servers
+It is specifically designed to connect to an Identity store (AD/Samba/LDAP, SQL Database, Web services/application, ...)
+and ease the integration of the Matrix ecosystem with an existing infrastructure, or to build a new one using lasting
+tools.
 
-mxisd provides an alternative to [sydent](https://github.com/matrix-org/sydent), while still connecting to the vector.im and matrix.org Identity servers, 
-by implementing the [Matrix Identity Service specification](https://matrix.org/docs/spec/identity_service/unstable.html).
+The core principle of mxisd is to map between Matrix IDs and 3PIDs (Thrid-party Identifiers) for the Homeserver and its
+users. 3PIDs can be anything that identify a user, like:
+- Full name
+- Email address
+- Phone number
+- Employee number
+- Skype/Live ID
+- Twitter handle
+- Facebook ID
+- ...
 
-mxisd only aims to support workflows that do NOT break federation or basic lookup processes of the Matrix ecosystem.
+mxisd is an enhanced Identity service, which implements the [Matrix Identity service API](https://matrix.org/docs/spec/identity_service/unstable.html)
+but also several other features that greatly enhance user experience within Matrix.
+
+mxisd is the one stop shop for anything regarding Authentication, Directory and Identity management in Matrix built as a
+single coherent product.
 
 # Features
-- Single lookup of 3PID (E-mail, phone number, etc.) by the Matrix Client or Homeserver.
-- Bulk lookups when trying to find possible matches within contacts in Android and iOS clients.
-- Bind of 3PID by a Matrix user within a Matrix client.
-- Support of invitation to rooms by e-mail with e-mail notification to invitee.
-- Authentication support in [synapse](https://github.com/matrix-org/synapse) via the [REST auth module](https://github.com/kamax-io/matrix-synapse-rest-auth).
+As a [regular Matrix Identity service](docs/features/identity.md):
+- Search for people by 3PID using its own Identity stores (LDAP, SQL, etc.)
+- Invite people to rooms by 3PID using its own Identity stores, with [notifications](docs/README.md)
+to the invitee (Email, SMS, etc.)
+- Allow users to add 3PIDs to their settings/profile
 
-In the pipe:
-- Support to proxy 3PID bindings in user profile to the central Matrix.org servers
+As an enhanced Identity service:
+- Use a recursive lookup mechanism when searching and inviting people by 3PID, allowing to fetch data from:
+  - Own Identity store
+  - Federated Identity servers, if applicable to the 3PID
+  - Arbitrary Identity servers
+  - Central Matrix Identity servers
+- [Extensive control of where 3PIDs are transmited](docs/sessions/3pid.md), so they are not leaked publicly by users
+- [Authentication support](docs/features/authentication.md) for [synapse](https://github.com/matrix-org/synapse) via the
+[REST auth module](https://github.com/kamax-io/matrix-synapse-rest-auth)
+- [Directory integration](docs/features/directory-users.md) which allows you to search for users within your
+organisation, even without prior Matrix contact
+- [Auto-fill of user profile](docs/features/authentication.md) (Display name, 3PIDs) via the
+[REST auth module](https://github.com/kamax-io/matrix-synapse-rest-auth)
 
-# Lookup Process
-Default Lookup strategy will use a priority order and a configurable recursive/local type of request.
+# Why use mxisd
+- Use your existing Identity store, do not duplicate information
+- Auto-fill user profiles with relevant information
+- As an organisation, stay in control of 3PIDs so they are not published to the central Matrix.org servers where they
+currently **cannot be removed**
+- Users can directly find each other using whatever attribute is relevant within your Identity store
+- Federate your Identity lookups so you can discover others and/or others can discover you, all with extensive ACLs
 
-## E-mail
-Given the 3PID `john.doe@example.org`, the following will be performed until a mapping is found:
-- LDAP: lookup the Matrix ID (partial or complete) from a configurable attribute using a dedicated query.
-- DNS: lookup another Identity Server using the domain part of an e-mail and:
-  - Look for a SRV record under `_matrix-identity._tcp.example.org`
-  - Lookup using the base domain name `example.org`
-- Forwarder: Proxy the request to other configurable identity servers.
+# Quick Start
+1. [Preparation](#preparation)
+2. [Install](#install)
+3. [Configure](#configure)
+4. [Integrate](#integrate)
+5. [Validate](#validate)
 
-## Phone number
-Given the phone number `+123456789`, the following lookup logic will be performed:
-- LDAP: lookup the Matrix ID (partial or complete) from a configurable attribute using a dedicated query.
-- Forwarder: Proxy the request to other configurable identity servers.
+Following these quick start instructions, you will have a basic setup that can perform recursive/federated lookups and
+talk to the central Matrix.org Identity service.  
+This will be a good ground work for further integration with your existing Identity stores.
 
-# Packages
-See [releases]((https://github.com/kamax-io/mxisd/releases)) for native installers of supported systems.  
-If none is available, please use other packages or build from source.
+## Preparation
+You will need:
+- Homeserver
+- Reverse proxy with regular TLS/SSL certificate (Let's encrypt) for your mxisd domain
 
-## Debian
-### Download
-See the [releases section](https://github.com/kamax-io/mxisd/releases).
+As synapse requires an HTTPS connection when talking to an Identity service, a reverse proxy is required as mxisd does
+not support HTTPS listener at this time.
 
-### Configure and run
-After installation:
-1. Copy the sample config file `/etc/mxisd/mxisd-sample.yaml` to `/etc/mxisd/mxisd.yaml`
-2. [Configure](#configuration)
-3. Start the service: `sudo systemctl start mxisd`
+For maximum integration, it is best to have your Homeserver and mxisd reachable via the same hostname.  
+You can also use a dedicated domain for mxisd, but will not have access to some features.
 
-### From source
-Requirements:
-- fakeroot
-- dpkg-deb
+Be aware of a [NAT/Reverse proxy gotcha](https://github.com/kamax-io/mxisd/wiki/Gotchas#nating) if you use the same
+hostname.
 
-Run:
-```
-./gradlew buildDeb 
-```
-You will find the debian package in `build/dist`
-
-## Docker
-```
-docker pull kamax/mxisd
-```
-
-For more info, see [the public repository](https://hub.docker.com/r/kamax/mxisd/)
-### From source
-[Build mxisd](#build) then build the docker image:
-```
-./gradlew dockerBuild
-```
-You can run a container of the given image and test it with the following command (adapt volumes host paths):
-```
-docker run -v /data/mxisd/etc:/etc/mxisd -v /data/mxisd/var:/var/mxisd -p 8090:8090 -t kamax/mxisd:latest-dev
-```
-
-# From Source
-## Requirements
-- JDK 1.8
-
-## Build
-```
-git clone https://github.com/kamax-io/mxisd.git
-cd mxisd
-./gradlew build
-```
-then see the [Configuration](#configuration) section.
-
-## Test build
-Start the server in foreground to validate the build:
-```
-java -jar build/libs/mxisd.jar
-```
-
-Ensure the signing key is available:
-```
-$ curl http://localhost:8090/_matrix/identity/api/v1/pubkey/ed25519:0
-{"public_key":"..."}
-```
-
-Test basic recursive lookup (requires Internet connection with access to TCP 443):
-```
-$ curl 'http://localhost:8090/_matrix/identity/api/v1/lookup?medium=email&address=mxisd-lookup-test@kamax.io'
-{"address":"mxisd-lookup-test@kamax.io","medium":"email","mxid":"@mxisd-lookup-test:kamax.io",...}
-```
-
-
-If you enabled LDAP, you can also validate your config with a similar request after replacing the `address` value with something present within your LDAP
-```
-curl "http://localhost:8090/_matrix/identity/api/v1/lookup?medium=email&address=john.doe@example.org"
-```
-
-If you plan on testing the integration with a homeserver, you will need to run an HTTPS reverse proxy in front of it
-as the reference Home Server implementation [synapse](https://github.com/matrix-org/synapse) requires a HTTPS connection
-to an ID server.  
-See the [Integration section](https://github.com/kamax-io/mxisd#integration) for more details.
+The following Quick Start guide assumes you will host the Homeserver and mxisd under the same hostname.  
+If you would like a high-level view of the infrastructure and how each feature is integrated, see the
+[dedicated document](docs/architecture.md)
 
 ## Install
-After [building](#build) the software, run all the following commands as `root` or using `sudo`
-1. Prepare files and directories:
+Install via:
+- [Debian package](docs/install/debian.md)
+- [Docker image](docs/install/docker.md)
+- [Sources](docs/build.md)
+
+See the [Latest release](https://github.com/kamax-io/mxisd/releases/latest) for links to each.
+
+## Configure
+Create/edit a minimal configuration (see installer doc for the location):
 ```
-# Create a dedicated user
-useradd -r mxisd
+matrix.domain: 'MyMatrixDomain.org'
+key.path: '/path/to/signing.key.file'
+storage.provider.sqlite.database: '/path/to/mxisd.db'
+```  
+- `matrix.domain` should be set to your Homeserver domain
+- `key.path` will store the signing keys, which must be kept safe!
+- `storage.provider.sqlite.database` is the location of the SQLite Database file which will hold state (invites, etc.)
 
-# Create bin directory
-mkdir /opt/mxisd
+If your HS/mxisd hostname is not the same as your Matrix domain, configure `server.name`.  
+Complete configuration guide is available [here](docs/configure.md).
 
-# Create config directory and set ownership
-mkdir /etc/mxisd
-chown mxisd /etc/mxisd
-
-# Create data directory and set ownership
-mkdir /var/opt/mxisd
-chown mxisd /var/opt/mxisd
-
-# Copy <repo root>/build/libs/mxisd.jar to bin directory
-cp ./build/libs/mxisd.jar /opt/mxisd/
-chown mxisd /opt/mxisd/mxisd.jar
-chmod a+x /opt/mxisd/mxisd.jar
-
-# Create symlink for easy exec
-ln -s /opt/mxisd/mxisd.jar /usr/bin/mxisd
+## Integrate
+For an overview of a typical mxisd infrastructure, see the [dedicated document](docs/architecture.md)
+### Reverse proxy
+#### Apache2
+In the VirtualHost handling the domain with SSL, add the following line and replace `0.0.0.0` by the right address/host.  
+**This line MUST be present before the one for the homeserver!**
+```
+ProxyPass /_matrix/identity/ http://0.0.0.0:8090/_matrix/identity/
 ```
 
-2. Copy the config file created earlier `./application.example.yaml` to `/etc/mxisd/mxisd.yaml`
-3. [Configure](#configuration)
-4. Copy `<repo root>/src/systemd/mxisd.service` to `/etc/systemd/system/` and edit if needed
-5. Enable service for auto-startup
+Typical VirtualHost configuration would be:
 ```
-systemctl enable mxisd
-```
-6. Start mxisd
-```
-systemctl start mxisd
+<VirtualHost *:443>
+    ServerName example.org
+    
+    ...
+    
+    ProxyPreserveHost on
+    ProxyPass /_matrix/identity/ http://10.1.2.3:8090/_matrix/identity/
+    ProxyPass /_matrix/ http://10.1.2.3:8008/_matrix/
+</VirtualHost>
 ```
 
-# Configuration
-After following the specific instructions to create a config file from the sample:
-1. Set the `matrix.domain` value to the domain value used in your Home Server configuration
-2. Set an absolute location for the signing keys using `key.path`
-3. Configure the E-mail invite sender with items starting in `invite.sender.email`
-
-In case your IS public domain does not match your Matrix domain, see `server.name` and `server.publicUrl` 
-config items.
-
-
-## Backends
-### LDAP (AD, Samba, LDAP)
-If you want to use LDAP backend as an Identity store:
-1. Enable it with `ldap.enabled`
-2. Configure connection options using items starting in `ldap.connection`
-3. You may want to valid default values for `ldap.attribute` items
-
-### SQL (SQLite, PostgreSQL)
-If you want to connect to use a synapse DB (SQLite or PostgreSQL) as Identity store, follow the example config for `sql` config items.
-
-### REST (Webapps/websites integration)
-If you want to use the REST backend as an Identity store:
-1. Enable it with `rest.enabled`
-2. Configure options starting with `rest` and see the dedicated documentation in `docs/backends/rest.md`
-
-# Network Discovery
-To allow other federated Identity Server to reach yours, the same algorithm used for Homeservers takes place:
-1. Check for the appropriate DNS SRV record
-2. If not found, use the base domain
- 
-If your Identity Server public hostname does not match your Matrix domain, configure the following DNS SRV entry 
-and replace `matrix.example.com` by your Identity server public hostname - **Make sure to end with a final dot!**
+### Synapse
+Add your mxisd domain into the `homeserver.yaml` at `trusted_third_party_id_servers` and restart synapse.  
+In a typical configuration, you would end up with something similair to:
 ```
-_matrix-identity._tcp.example.com. 3600 IN SRV 10 0 443 matrix.example.com.
+trusted_third_party_id_servers:
+    - matrix.org
+    - vector.im
+    - example.org
 ```
-This would only apply for 3PID that are DNS-based, like e-mails. For anything else, like phone numbers, no federation 
-is currently possible.  
+It is recommended to remove `matrix.org` and `vector.im` so only your own Identity server is allowed by synapse. 
 
-The port must be HTTPS capable. Typically, the port `8090` of mxisd should be behind a reverse proxy which does HTTPS.
-See the [integration section](#integration) for more details.
+### Federation and network discovery
+See the [dedicated document](docs/features/federation.md).
 
-# Integration
-- [HTTPS and Reverse proxy](https://github.com/kamax-io/mxisd/wiki/HTTPS)
-- [synapse](https://github.com/kamax-io/mxisd/wiki/Homeserver-Integration) as Identity server
-- [synapse with REST auth module](https://github.com/kamax-io/matrix-synapse-rest-auth/blob/master/README.md) 
-as authentication module
+## Validate
+Log in using your Matrix client and set `https://example.org` as your Identity server URL, replacing `example.org` by
+the relevant hostname which you configured in your reverse proxy.  
+Invite `mxisd-lookup-test@kamax.io` to a room, which should be turned into a Matrix invite to `@mxisd-lookup-test:kamax.io`.  
+**NOTE:** you might not see a Matrix suggestion for the e-mail address, which is normal. Still proceed with the invite.
+  
+If it worked, it means you are up and running and can enjoy mxisd in its basic mode! Congratulations!  
+If it did not work, [get in touch](#support) and we'll do our best to get you started.
+
+You can now integrate mxisd further with your infrastructure using the various [features](docs/README.md) guides.

+
+# FAQ
+### Do I need to use mxisd if I run a Homeserver?
+No, but it is recommended, even if you don't use any backends or integration.
+
+mxisd in its default configuration will use federation and involve the central Matrix.org Identity servers when
+performing queries, giving you access to at least the same information as if you were not running it.
+
+It will also give your users a choice to make their 3PIDs available publicly, ensuring they are made aware of the
+privacy consequences, which is not the case with the central Matrix.org servers.
+
+So mxisd is like your gatekeeper and guardian angel. It does not change what you already know, just adds some nice
+simple features on top of it.
+
+### I already use the synapse LDAP3 auth provider, why should I care about mxisd?
+The [synapse LDAP3 auth provider](https://github.com/matrix-org/matrix-synapse-ldap3) only handles on specific flow:
+validate credentials at login.
+
+It does not:
+- Auto-provision user profiles
+- Integrate with Identity management
+- Integrate with Directory searches
+- Protect you against the username case sensitivites issues in synapse
+
+mxisd is a replacement and enhancement of it, and also offers coherent results in all areas, which LDAP3 auth provider
+does not.
+
+### I saw that sydent is the official Identity server implemenation of the Matrix team, I should use that!
+You can, but [sydent](https://github.com/matrix-org/sydent):
+- [should not be used and/or self-hosted](https://github.com/matrix-org/sydent/issues/22)
+- is not meant to be linked to a specific Homeserver / domain
+- cannot handle federation or proxy lookups, effectively isolating your users from the rest of the network
+- forces you to duplicate all your identity data, so people can be found by 3PIDs
+- forces users to enter all their emails and phone numbers manually in their profile
+
+So really, you should go with mxisd.
+
+### I'm not sure I understand what an "Identity server" is supposed to be or do
+The current Identity service API is more a placeholder, as the Matrix devs did not have time so far to really work on
+what they want to do with that part of the ecosystem. Therefore, "Identity" is a misleading word currently.  
+Given the scope of the current Identity Service API, it would be best called "Invitation service".
+
+Because the current scope is so limited and no integration is done with the Homeserver, there was a big lack of features
+for groups/corporations/organisation. This is where mxisd comes in.
+
+mxisd implements the Identity Service API and also a set of features which are expected by regular users, truly living
+up to its "Identity server" name.
+
+### So mxisd is just a big hack! I don't want to use non-official features!
+mxisd primary concern is to always be compatible with the Matrix ecosystem and the Identity service API.  
+Whenever the API will be updated and/or enhanced, mxisd will follow, remaining 100% compatible with the ecosystem.
+
+We also directly talk with the Matrix developers to ensure all features we implement have their approval, and that we
+are in line with their vision of Identity management within the Matrix ecosystem.
+
+Therefore, using mxisd is a safe choice. It will be like using the central Matrix.org Identity servers, yet not closing
+the door to very nice enhancements and integrations.
+
+### Should I use mxisd if I don't host my own Homeserver?
+No

-
-# In case no binding is found, query an application server which implements the single lookup end-point

-#
-# If a binding is returned, the application server is not expected to sign the message as it is not meant to be
-# reachable from the outside.
-# If a signature is provided, it will be discarded/replaced by this IS implementation (to be implemented).
-#
-# IMPORTANT: This bypass the regular Invite system of the Homeserver. It will be up to the Application Server
-# to handle such invite. Also, if the bridged user were to actually join Matrix later, or if a 3PID binding is found
-# room rights and history would not be transferred, as it would appear as a regular Matrix user to the Homeserver.

-#### How to map Matrix attributes with LDAP attributes when performing lookup/auth
-#
-# How should we resolve the Matrix ID in case of a match using the attribute.
-#
-# The following type are supported:
-# - uid : the attribute only contains the UID part of the Matrix ID. e.g. 'john.doe' in @john.doe:example.org
-# - mxid : the attribute contains the full Matrix ID - e.g. '@john.doe:example.org'
-#
-#ldap.attribute.uid.type: 'uid'
-
-
-# The attribute containing the binding itself. This value will be used differently depending on the type.
-#
-# /!\ This should match the synapse LDAP Authenticator 'uid' configuration /!\
-#
-# Typical values:
-# - For type 'uid': 'userPrincipalName' or 'uid' or 'saMAccountName'
-# - For type 'mxid', regardless of the directory type, we recommend using 'pager' as it is a standard attribute and
-#   is typically not used.
-#
-#ldap.attribute.uid.value: 'userPrincipalName'
-
-
-# The display name of the user
-#
-#ldap.attribute.name: 'displayName'
-
-
-#### Configuration section relating the authentication of users performed via LDAP.
-#
-# This can be done using the REST Auth module for synapse and pointing it to the identity server.
-# See https://github.com/kamax-io/matrix-synapse-rest-auth
-#
-# During authentication, What to filter potential users by, typically by using a dedicated group.
-# If this value is not set, login check will be performed for all entities within the LDAP
-#
-# Example: (memberOf=CN=Matrix Users,CN=Users,DC=example,DC=org)
-#
-#ldap.auth.filter: ''
-
-

-#
-# E-mail query
-#
-#ldap.identity.medium.email: "(|(mailPrimaryAddress=%3pid)(mail=%3pid)(otherMailbox=%3pid))"
-
-
-# Phone numbers query
-#
-# Phone numbers use the MSISDN format: https://en.wikipedia.org/wiki/MSISDN
-# This format does not include international prefix (+ or 00) and therefore has to be put in the query.
-# Adapt this to your needs for each attribute.

 It supports the following mxisd flows:

 Endpoint values can handle two formats:
 - URL Path starting with `/` that gets happened to the `rest.host`
 - Full URL, if you want each endpoint to go to a specific server/protocol/port
 
-`rest.host` is only mandatory if at least one endpoint is not a full URL.

+- JDK 1.8
+
+### Build
+```
+git clone https://github.com/kamax-io/mxisd.git
+cd mxisd
+./gradlew build
+```
+
+Create a new configuration file by coping `application.example.yaml` to `application.yaml` and edit to your needs.  
+For advanced configuration, see the [Configure section](configure.md).
+
+Start the server in foreground to validate the build and configuration:
+```
+java -jar build/libs/mxisd.jar
+```
+
+Ensure the signing key is available:
+```
+$ curl 'http://localhost:8090/_matrix/identity/api/v1/pubkey/ed25519:0'

+```
+
+If you plan on testing the integration with a homeserver, you will need to run an HTTPS reverse proxy in front of it
+as the reference Home Server implementation [synapse](https://github.com/matrix-org/synapse) requires a HTTPS connection

+# Configuration
+- [Syntax](#syntax)
+- [Variables](#variables)
+- [Categories](#categories)
+
+## Syntax
+The configuration file is YAML based, allowing two types of syntax.
+
+Properties-like:
+```
+my.config.item: 'value'
+```
+
+Object-like:
+```
+my:
+  config:
+    item: 'value'
+
+```
+These can also be combined within the same file.  
+Both syntax will be used interchangeably in these documents.
+
+Default values for each possible option are documented [here](../src/main/resources/application.yaml)
+
+## Variables
+It is possible to copy the value of a configuration item into another using the syntax `${config.key.item}`.  
+Example that will copy the value of `matrix.domain` into `server.name`:
+```
+matrix:
+  domain: 'example.org'
+
+server:
+  name: '${matrix.domain}'
+```
+
+**WARNING:** mxisd might overwrite/adapt some values during launch. Those changes will not be reflected into copied keys.
+
+## Categories
+For each category below, the base configuration path will be given, which needs to be appened to every configuration
+item described.
+
+Example: if the base path was `basePath` and the following table was given:
+
+| Name | Purpose |
+|------|---------|
+| item1 | To give an example |
+| item2 | To give another example |
+
+The following configurations could be used, all being equivalent:
+```
+basePath.item1: 'myValue'
+basePath.item2: 'myOtherValue'
+```
+```
+basePath:
+  item1: 'myValue'
+  item2: 'myOtherValue'
+```
+```
+basePath.item1: 'myValue'
+basePath:
+  item2: 'myOtherValue'
+```
+
+---
+
+In case a relative base path is given, it is appended to the one above.
+
+Example: With base path `basePath`, the relative base `relativeBasePath` and the following table:
+  
+| Name | Purpose |
+|------|---------|
+| item1 | To give an example |
+| item2 | To give another example |
+
+The following configurations could be used, all being equivalent:
+```
+basePath.relativeBasePath.item1: 'myValue'
+basePath.relativeBasePath.item2: 'myOtherValue'
+```
+```
+basePath:
+  relativeBasePath:
+    item1: 'myValue'
+    item2: 'myOtherValue'

+    - 'https://matrix.org'
+```
+Create a list under the label `root` containing a single Identity server, `https://matrix.org`
+### Server
+| Name | Purpose |
+|------|---------|
+| `name` | Public hostname of mxisd, if different from the Matrix domain |
+| `port` | HTTP port to listen on (unencrypted) |
+| `publicUrl` | Defaults to `https://${server.name}` |
+
+### Storage
+Base path: `storage`

+
+## Description
+This feature allows you to search for existing and/or potential users that are already present in your Identity backend
+or that already share a room with you on the Homeserver.
+
+Without any integration, synapse:
+- Only search within the users **already** known to you
+- Only search on the Display Name and the Matrix ID
+
+With mxisd integration, you can:
+- Search on Matrix ID, Display name and 3PIDs (Email, phone numbers) of any users already in your configured backend
+- Search for users which you are not in contact with yet. Super useful for corporations who want to give Matrix access
+internally, so users can just find themselves **prior** to having any common room(s)
+- Use any attribute of your backend to extend the search!
+- Include your homeserver search results to those found by mxisd (default behaviour, no configuration required)
+
+By integrating mxisd, you get the default behaviour with all the extras, ensuring your users will always find each other.
+
+## Overview
+This is performed by intercepting the Homeserver endpoint `/_matrix/client/r0/user_directory/search` like so:
+```
+           +----------------------------------------------+
+Client --> | Reverse proxy                                                                         Step 2
+           |                                              Step 1    +-------------------------+
+           |   /_matrix/client/r0/user_directory/search ----------> |                         |  Search in   +---------+
+           |                        /\                              | mxisd - Identity server | -----------> | Backend |
+           |   /_matrix/*            \----------------------------- |                         |  all users   +---------+
+           |        |            Step 4: Send back merged results   +-------------------------+
+           +        |                                                            |
+                    |                                                          Step 3
+                    |                                                            |
+                    |    +------------+                                Search in known users
+                    \--> | Homeserver | <----------------------------------------/
+                         +------------+   /_matrix/client/r0/user_directory/search
+```
+Steps:
+1. The intercepted request is directly sent to mxisd instead of the Homeserver.
+2. Enabled backends are queried for any match on the search value sent by the client.
+3. The Homeserver, from which the request was intercepted, is queried using the same request as the client.
+Its address is resolved using the DNS Overwrite feature to reach its internal address on a non-encrypted port.
+4. Results from backends and the Homeserver are merged together and sent back to the client, believing it was the HS
+which directly answered the request.
+
+## Requirements
+- Reverse proxy setup, which you should already have in place if you use mxisd
+- Compatible backends:
+  - LDAP
+  - SQL
+  - REST
+  
+## Configuration
+### Reverse Proxy
+Apache2 configuration to put under the relevant virtual domain:
+```
+ProxyPreserveHost on
+ProxyPass /_matrix/identity/ http://mxisdInternalIpAddress:8090/_matrix/identity/
+ProxyPass /_matrix/client/r0/user_directory/ http://mxisdInternalIpAddress:8090/_matrix/client/r0/user_directory/
+ProxyPass /_matrix/ http://HomeserverInternalIpAddress:8008/_matrix/
+```
+`ProxyPreserveHost` or equivalent must be enabled to detect to which Homeserver mxisd should talk to when building
+results.
+
+### DNS Overwrite
+Just like you need to configure a reverse proxy to send client requests to mxisd, you also need to configure mxisd with
+the internal IP of the Homeserver so it can talk to it directly to integrate its directory search.
+
+To do so, use the following configuration:
+```
+dns.overwrite.homeserver.client:
+  - name: 'example.org'
+    value: 'http://localhost:8008'
+```
+`name` must be the hostname of the URL that clients use when connecting to the Homeserver.  
+In case the hostname is the same as your Matrix domain, you can use `${matrix.domain}` to auto-populate the value using
+the `matrix.domain` configuration option and avoid duplicating it.
+
+`value` is the base intenral URL of the Homeserver, without any `/_matrix/..` or trailing `/`.
+
+### Backends
+#### LDAP
+To ensure Directory feature works, here's how the LDAP configuration should look like:
+```
+ldap:
+  enabled: false
+  filter: '(memberOf=CN=Matrix Users,OU=Groups,DC=example,DC=org)'
+  connection:
+    host: 'ldapIpOrDomain'
+    bindDn: 'CN=Matrix Identity Server,OU=Accounts,DC=example,DC=org'
+    bindPassword: 'mxisd'
+    baseDn: 'OU=Accounts,DC=example,DC=org'
+  attribute:
+    uid:
+      type: 'uid'
+      value: 'userPrincipalName'
+    name: 'displayName'
+    threepid:
+      email:
+        - 'mailPrimaryAddress'
+        - 'mail'
+        - 'otherMailbox'
+      msisdn:
+        - 'telephoneNumber'
+        - 'mobile'
+        - 'homePhone'
+        - 'otherTelephone'
+        - 'otherMobile'
+        - 'otherHomePhone'
+  directory:
+    attribute:
+      other:
+        - 'employeeNumber'
+        - 'someOtherAttribute'
+```
+Only include the `attribute` sub-sections if you would like to set another value. Else, it is best not to include them
+to inherit the default values.
+
+If you would like to include an attribute which is not a display name or a 3PID, you can use the
+`directory.attribute.other` to list any extra attributes you want included in searches. If you do not want to include
+any extra attribute, that configuration section can be skipped. 
+
+#### SQL
+If you plan to integrate directory search directly with synapse, use the `synapseSql` provider, based on the following
+config:
+```
+synapseSql:
+  enabled: true
+  type: <database ID>
+  connection: '<connection info>'
+```
+`type` and `connection`, including any other configuration item, follow the same values as the regular [SQL backend](../backends/sql.md).
+
+---
+
+For the regular SQL backend, the following configuration items are available:
+```
+sql:
+  directory:
+    enabled: true
+    query:
+      name:
+        type: 'localpart'
+        value: 'SELECT idColumn, displayNameColumn FROM table WHERE displayNameColumn LIKE ?'
+      threepid:

+For each query, `type` can be used to tell mxisd how to process the ID column:
+- `localpart` will append the `matrix.domain` to it
+- `mxid` will use the ID as-is. If it is not a valid Matrix ID, the search will fail.
+
+`value` is the SQL query and must return two columns:
+- The first being the User ID

+To allow other federated Identity Server to reach yours, the same algorithm used for Homeservers takes place:
+1. Check for the appropriate DNS SRV record
+2. If not found, use the base domain
+
+## Configuration
+If your Identity Server public hostname does not match your Matrix domain, configure the following DNS SRV entry 
+and replace `matrix.example.com` by your Identity server public hostname - **Make sure to end with a final dot!**
+```
+_matrix-identity._tcp.example.com. 3600 IN SRV 10 0 443 matrix.example.com.
+``` 
+This would only apply for 3PID that are DNS-based, like e-mails. For anything else, like phone numbers, no federation 
+is currently possible.  
+
+The port must be HTTPS capable which is what you get in a regular setup with a reverse proxy from 443 to TCP 8090 of mxisd.

+# Notifications: Generate from templates
+To create notification content, you can use the `template` generator if supported for the 3PID medium which will read
+content from configured files.
+
+Placeholders can be integrated into the templates to dynamically populate such content with relevant information like
+the 3PID that was requested, the domain of your Identity server, etc.
+
+Templates can be configured for each event that would send a notification to the end user. Events share a set of common
+placeholders and also have their own individual set of placeholders.
+
+## Configuration

+```
