+## Invitations
+### Expiration
+#### Overview
+Matrix does not provide a mean to remove/cancel pending 3PID invitations with the APIs. The current reference
+implementations also do not provide any mean to do so. This leads to 3PID invites forever stuck in rooms.
+
+To provide this functionality, ma1sd uses a workaround: resolve the invite to a dedicated User ID, which can be
+controlled by ma1sd or a bot/service that will then reject the invite.
+
+If this dedicated User ID is to be controlled by ma1sd, the [Application Service](experimental/application-service.md)
+feature must be configured and integrated with your Homeserver, as well as the *Auto-reject 3PID invite capability*.
+
+#### Configuration
+```yaml
+invite:
+  expiration:
+    enabled: true/false
+    after: 5
+    resolveTo: '@john.doe:example.org'
+```
+`enabled`
+- Purpose: Enable or disable the invite expiration feature.
+- Default: `true`
+
+`after` 
+- Purpose: Amount of minutes before an invitation expires.
+- Default: `10080` (7 days)
+
+`resolveTo`
+- Purpose: Matrix User ID to resolve the expired invitations to.
+- Default: Computed from `appsvc.user.inviteExpired` and `matrix.domain`
+
+### Policies
+3PID invite policies are the companion feature of [Registration](registration.md). While the Registration feature acts on
+requirements for the invitee/register, this feature acts on requirement for the one(s) performing 3PID invites, ensuring
+a coherent system.
+
+It relies on only allowing people with specific [Roles](profile.md) to perform 3PID invites. This would typically allow
+a tight-control on a server setup with is "invite-only" or semi-open (relying on trusted people to invite new members).
+
+It's a middle ground between a closed server, where every user must be created or already exists in an Identity store,
+and an open server, where anyone can register.
+ 
+#### Integration
+Because Identity Servers do not control 3PID invites as per Matrix spec, ma1sd needs to intercept a set of Homeserver
+endpoints to apply the policies.
+
+##### Reverse Proxy
+###### nginx
+**IMPORTANT**: Must be placed before your global `/_matrix` entry:
+```nginx
+location ~* ^/_matrix/client/r0/rooms/([^/]+)/invite$ {
+    proxy_pass		    http://127.0.0.1:8090;
+    proxy_set_header	Host $host;
+    proxy_set_header	X-Forwarded-For $remote_addr;
+}
+```
+
+#### Configuration
+The only policy currently available is to restrict 3PID invite to users having a specific (set of) role(s), like so:
+
+```yaml
+invite:
+  policy:
+    ifSender:

+## Overview
+**NOTE**: This feature is beta: it is considered stable enough for production but is incomplete and may contain bugs.
+
+Registration is an enhanced feature of ma1sd to control registrations involving 3PIDs on a Homeserver based on policies:
+- Match pending 3PID invites on the server
+- Match 3PID pattern, like a specific set of domains for emails
+- In further releases, use 3PIDs found in Identity stores
+
+It aims to help open or invite-only registration servers control what is possible to do and ensure only approved people
+can register on a given server in a implementation-agnostic manner.
+
+**IMPORTANT:** This feature does not control registration in general. It only acts on endpoints related to 3PIDs during
+the registration process.  
+As such, it relies on the homeserver to require 3PIDs with the registration flows.
+
+This feature is not part of the Matrix Identity Server spec.
+
+## Integration
+ma1sd needs to be integrated at several levels for this feature to work:
+- Reverse proxy: intercept the 3PID register endpoints and act on them
+- Homeserver: require 3PID to be part of the registration data
+
+Later version(s) of this feature may directly control registration itself to create a coherent experience
+### Reverse Proxy

+#### Apache2
+> TBC
+
+### Homeserver
+#### Synapse
+```yaml
+enable_registration: true
+registrations_require_3pid:
+  - email
+```
+
+## Configuration
+See the [Configuration](../configure.md) introduction doc on how to read the configuration keys.  
+An example of working configuration is available at the end of this section.
+### Enable/Disable
+`register.allowed`, taking a boolean, can be used to enable/disable registration if the attempt is not 3PID-based.  
+`false` is the default value to prevent open registration, as you must allow it on the homeserver side.
+
+### For invites
+`register.invite`, taking a boolean, controls if registration can be made using a 3PID which matches a pending 3PID invite.  
+`true` is the default value.
+
+### 3PID-specific
+At this time, only `email` is supported with 3PID specific configuration with this feature.
+
+#### Email
+**Base key**: `register.threepid.email`
+
+##### Domain whitelist/blacklist
+If you would like to control which domains are allowed to be used when registering with an email, the following sub-keys
+are available:
+- `domain.whitelist`
+- `domain.blacklist`
+
+The value format is an hybrid between glob patterns and postfix configuration files with the following syntax:
+- `*<domain>` will match the domain and any sub-domain(s)
+- `.<domain>` will only match sub-domain(s)
+- `<domain>` will only match the exact domain
+
+The following table illustrates pattern and matching status against example values:
+
+| Config value   | Matches `example.org` | Matches `sub.example.org` |
+|--------------- |-----------------------|---------------------------|
+| `*example.org` | Yes                   | Yes                       |
+| `.example.org` | No                    | Yes                       |
+| `example.org`  | Yes                   | No                        |
+
+### Example
+For the following example configuration:
+```yaml
+register:
+  policy:
+    threepid:
+      email:
+        domain:
+          whitelist:
+            - '*example.org'
+            - '.example.net'
+            - 'example.com'
+```
+- Users can register using 3PIDs of pending invites, being allowed by default.
+- Users can register using an email from `example.org` and any sub-domain, only sub-domains of `example.net` and `example.com` but not its sub-domains.
+- Otherwise, user registration will be denied.
+
+## Usage
+Nothing special is needed. Register using a regular Matrix client.

+# Security hardening
+## Overview
+This document outlines the various operations you may want to perform to increase the security of your installation and
+avoid leak of credentials/key pairs
+
+## Configuration
+Your config file should have the following ownership:
+- Dedicated user for ma1sd, used to run the software
+- Dedicated group for ma1sd, used by other applications to access and read configuration files
+
+Your config file should have the following access:
+- Read and write for the ma1sd user
+- Read for the ma1sd group
+- Nothing for others
+
+This translates into `640` and be applied with `chmod 640 /path/to/config/file.yaml`.
+
+## Data
+The only sensible place is the key store where ma1sd's signing keys are stored. You should therefore limit access to only
+the ma1sd user, and deny access to anything else.
+
+Your key store should have the following access:
+- Read and write for the ma1sd user
+- Nothing for the ma1sd group
+- Nothing for others
+
+The identity store can either be a file or a directory, depending on your version. v1.4 and higher are using a directory,
+everything before is using a file.
+- If your version is directory-based, you will want to apply chmod `700` on it.
+- If your version is file-based, you will want to apply chmod `600` on it.

-# 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.
+# Notifications: Template generator
+Most of the Identity actions will trigger a notification of some kind, informing the user of some confirmation, next step
+or just informing them about the current state of things.
 
-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.
+Those notifications are by default generated from templates and by replacing placeholder tokens in them with the relevant
+values of the notification. It is possible to customize the value of some placeholders, making easy to set values in the builtin templates, and/or
+provide your own custom templates.
 
-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.
+Templates for the following events/actions are available:
+- [3PID invite](../../features/identity.md)
+- [3PID session: validation](../session/session.md)
+- [3PID session: unbind](https://github.com/kamax-matrix/ma1sd/wiki/ma1sd-and-your-privacy#improving-your-privacy-one-commit-at-the-time)
+- [Matrix ID invite](../../features/experimental/application-service.md#email-notification-about-room-invites-by-matrix-ids)
+
+## Placeholders
+All placeholders **MUST** be surrounded with `%` in the template. Per example, the `DOMAIN` placeholder would become
+`%DOMAIN%` within the template. This ensures replacement doesn't happen on non-placeholder strings.
+
+### Global

+## Templates
+ma1sd comes with a set of builtin templates to easily get started. Those templates can be found
+[in the repository](https://github.com/ma1uta/ma1sd/tree/master/src/main/resources/threepids). If you want to use
+customized templates, we recommend using the builtin templates as a starting point.
+
+> **NOTE**: The link above point to the latest version of the built-in templates. Those might be different from your
+version. Be sure to view the repo at the current tag.
 
 ## Configuration
+All configuration is specific to [3PID mediums](https://matrix.org/docs/spec/appendices.html#pid-types) and happen
+under the namespace `threepid.medium.<medium>.generators.template`.
+
+Under such namespace, the following keys are available:
+- `invite`: Path to the 3PID invite notification template
+- `session.validation`: Path to the 3PID session validation notification template
+- `session.unbind`: Path to the 3PID session unbind notification template
+- `generic.matrixId`: Path to the Matrix ID invite notification template
+- `placeholder`: Map of key/values to set static values for some placeholders.
+
+The `placeholder` map supports the following keys, mapped to their respective template placeholders:
+- `REGISTER_URL`
+
+### Example
+#### Simple
+```yaml
+threepid:
+  medium:
+    email:
+      generators:
+        template:
+          placeholder:
+            REGISTER_URL: 'https://matrix-client.example.org'
+```
+In this configuration, the builtin templates are used and a static value for the `REGISTER_URL` is set, allowing to point
+a newly invited user to a webapp allowing the creation of its account on the server.
+
+#### Advanced
 To configure paths to the various templates:
 ```yaml
 threepid:
   medium:
-    <YOUR 3PID MEDIUM HERE>:
+    email:
       generators:
         template:
           invite: '/path/to/invite-template.eml'
           session:
-            validation:
-              local: '/path/to/validate-local-template.eml'
-              remote: 'path/to/validate-remote-template.eml'
+            validation: '/path/to/validate-template.eml'
+            unbind:
+              notification: '/path/to/unbind-notification-template.eml'
           generic:
             matrixId: '/path/to/mxid-invite-template.eml'
+          placeholder:
+            REGISTER_URL: 'https://matrix-client.example.org'
 ```
-The `template` generator is usually the default, so no further configuration is needed.

 ## Overview
 When adding an email, a phone number or any other kind of 3PID (Third-Party Identifier) in a Matrix client,
 the identity server is contacted to validate the 3PID.
 
-To validate the 3PID the identity server sends a message to the 3PID (e.g. an
-email) with a hyperlink back to a web-page managed by the identity server to
-confirm ownership of the 3PID.
+To validate the 3PID, the identity server creates a session associated with a secret token. That token is sent via a message
+to the 3PID (e.g. an email) with a the necessary info so the user can submit them to the Identity Server, confirm ownership
+of the 3PID.
 
-Once this 3PID is validated, the Homeserver will publish the user Matrix ID on the Identity Server and
-add this 3PID to the Matrix account which initiated the request.
+Once this 3PID is validated, the Homeserver will request that the Identity Server links the provided user Matrix ID with
+the 3PID session and finally add the 3PID to its own data store.
 
 This serves two purposes:
 - Add the 3PID as an administrative/login info for the Homeserver directly
-- Publish, or *Bind*, the 3PID so it can be queried from Homeservers and clients when inviting someone in a room
+- Links, called *Bind*, the 3PID so it can be queried from Homeservers and clients when inviting someone in a room
 by a 3PID, allowing it to be resolved to a Matrix ID.
 
-## Federation
+## Restrictions
+### Bindings
+ma1sd does not store bindings directly. While a user can see its email, phone number or any other 3PID in its
+settings/profile, it does **NOT** mean it is published/saved anywhere or can be used to invite/search the user.
+
+Identity stores are the ones holding such data, irrelevant if a user added a 3PID to their profile. When queried for
+bindings, ma1sd will query Identity stores which are responsible to store this kind of information.
+
+Therefore, by default, any 3PID added to a user profile which is NOT within a configured and enabled Identity backend
+will simply not be usable for search or invites, **even on the same Homeserver!**  
+
+To have such 3PID bindings available for search and invite queries on synapse, use its dedicated
+[Identity store](../../stores/synapse.md).
+
+### Federation
 In a federated set up, identity servers must cooperate to find the Matrix ID associated with a 3PID.
 
 Federation is based on the principle that each server is responsible for its own (dns) domain.
@@ -43,68 +53,22 @@ Example: a user from Homeserver `example.org` adds an email `john@example.com`.
 Federated identity servers would try to find the identity server at `example.com` and ask it for the Matrix ID of associated with `john@example.com`.
 
 Nevertheless, Matrix users might add 3PIDs that are not associated to a domain, for example telephone numbers.
-Or they might even add 3PIDs associated to a different domain (such as an email address hosted by gmail).
-Such 3PIDs cannot be resolved in a federated way.
+Or they might even add 3PIDs associated to a different domain (such as an email address hosted by Gmail).
+Such 3PIDs cannot be resolved in a federated way and will not be found from other servers.
 
 Example: a user from Homeserver `example.org` adds an email `john@gmail.com`.  
 If a federated lookup was performed, Identity servers would try to find the 3PID bind at the `gmail.com` server, and
 not `example.org`.
 
-In order to resolve such 3PIDs, i.e. 3PIDs that cannot be resolved in a Federated way, an identity server can be configured such that
-- 3PIDs that cannot be resolved locally or using federation, are fowarded to another global identity server.
-- registration of new 3PIDs that cannot be looked up in a federated fashion, is forwarded to another global identity server.
-
-By forwarding a 3PIDs registration the identity creates a *Remote session* and *Remote bind*, effectively starting a new 3PID session with another Identity server on
-behalf of the user. 
-
-To ensure lookup works consistency within the current Matrix network, the central Matrix.org Identity Server should be
-used to store *remote* sessions and binds.
-
-However, at the time of writing, the Matrix specification and the central Matrix.org servers do not allow to remote a 3PID bind.
-This means that once a 3PID is published (email, phone number, etc.), it cannot be easily removed
-and would require contacting the Matrix.org administrators for each bind individually.
-This poses a privacy, control and security concern, especially for groups/corporations that want to keep a tight control
-on where such identifiers can be made publicly visible.
-
-To ensure full control, validation management relies on two concepts:
-- The scope of 3PID being validated
-- The scope of 3PID sessions that should be possible/offered
-
-### 3PID scope
-3PID can either be scoped as local or remote.
-
-Local means that they can be looked up using federation and that such a federation call would end up on the local
-Identity Server.  
-Remote means that they cannot be lookup using federation or that a federation call would not end up on the local
-Identity Server.
-
-Email addresses can either be local or remote 3PID, depending on the domain. If the address is one from the configured
-domain in the Identity server, it will be scoped as local. If it is from another domain, it will be as remote.
-
-Phone number can only be scoped as remote, since there is currently no way to perform DNS queries that would lead back
-to the Identity server who validated the phone number.
-
-### Session scope
-Sessions can be scoped as:
-- Local only - validate 3PIDs directly, do not allow the creation of 3PID sessions on a remote Identity server.
-- Local and Remote - validate 3PIDs directly, offer users to option to also validate and bind 3PID on another server.
-- Remote only - validate and bind 3PIDs on another server, no validation or bind done locally.

 ## Notifications
 3PIDs are validated by sending a pre-formatted message containing a token to that 3PID address, which must be given to the
 Identity server that received the request. This is usually done by means of a URL to visit for email or a short number
 received by SMS for phone numbers.

 ### Scenarios
-It is important to keep in mind that mxisd does not create bindings, irrelevant if a user added a 3PID to their profile.  
-Instead, when queried for bindings, mxisd will query Identity stores which are responsible to store this kind of information.
-
-This has the side effect that any 3PID added to a user profile which is NOT within a configured and enabled Identity backend
-will simply not be usable for search or invites, **even on the same Homeserver!**  
-mxisd does not store binds on purpose, as one of its primary goal is to ensure maximum compatibility with federation
-and the rest of the Matrix ecosystem is preserved.
-
-Nonetheless, because mxisd also aims at offering support for tight control over identity data, it is possible to have
-such 3PID bindings available for search and invite queries on synapse with the corresponding [Identity store](../../stores/synapse.md).
-
-See the [Local sessions only](#local-sessions-only) use case for more information on how to configure.
-
-#### Default
-By default, mxisd allows the following:
-
-|                 | Local Session     | Remote Session |
-|-----------------|-------------------|----------------|
-| **Local 3PID**  | Yes               | Yes, offered   |
-| **Remote 3PID** | No, Remote forced | Yes            |
-
-This is usually what people expect and will feel natural to users and does not involve further integration.
-
-This allows to stay in control for e-mail addresses which domain matches your Matrix environment, still making them
-discoverable with federation but not recorded in a 3rd party Identity server which is not under your control.  
-Users still get the possibility to publish globally their address if needed.
-
-Other e-mail addresses and phone number will be redirected to remote sessions to ensure full compatibility with the Matrix
-ecosystem and other federated servers.
-
-#### Local sessions only
-**NOTE:** This does not affect 3PID lookups (queries to find Matrix IDs). See [Federation](../../features/federation.md)
-to disable remote lookup for those.
-
-This configuration ensures maximum confidentiality and privacy.
-Typical use cases:
-- Private Homeserver, not federated
-- Internal Homeserver without direct Internet access
-- Custom product based on Matrix which does not federate
-
-No 3PID will be sent to a remote Identity server and all validation will be performed locally.  
-On the flip side, people with *Remote* 3PID scopes will not be found from other servers.
-
-Use the following values:
-```yaml
-session:
-  policy:
-    validation:
-      enabled: true
-      forLocal:
-        enabled: true
-        toLocal: true
-        toRemote:
-          enabled: false
-      forRemote:
-        enabled: true
-        toLocal: true
-        toRemote:
-          enabled: false
-```
-
-**IMPORTANT**: When using local-only mode and if you are using synapse, you will also need to enable its dedicated Identity
-store if you want user searches and invites to work. To do so, see the [dedicated document](../../stores/synapse.md).
-
-#### Remote sessions only
-This configuration ensures all 3PID are made public for maximum compatibility and reach within the Matrix ecosystem, at
-the cost of confidentiality and privacy.  
-
-Typical use cases:
-- Public Homeserver
-- Homeserver with registration enabled
-
-Use the following values:
-```yaml
-session:
-  policy:
-    validation:
-      enabled: true
-      forLocal:
-        enabled: true
-        toLocal: false
-        toRemote:
-          enabled: true
-      forRemote:
-        enabled: true
-        toLocal: false
-        toRemote:
-          enabled: true
-```
-
 #### Sessions disabled
-This configuration would disable 3PID session altogether, preventing users from adding emails and/or phone numbers to
-their profiles.  
-This would be used if mxisd is also performing authentication for the Homeserver, typically with synapse and the
-[REST password provider](https://github.com/kamax-io/matrix-synapse-rest-auth).
+This configuration would disable 3PID sessions altogether, preventing users from validating emails and/or phone numbers
+and any subsequent actions that requires them, like adding them to their profiles.
   
-**This mode comes with several important restrictions:**
-- This does not prevent users from removing 3PID from their profile. They would be unable to add them back!
-- This prevents users from initiating remote session to make their 3PID binds globally visible
-
-It is therefore recommended to not fully disable sessions but instead restrict specific set of 3PID and Session scopes.
+This would be used if ma1sd is also performing authentication for the Homeserver, typically with synapse and the
+[REST password provider](https://github.com/ma1uta/matrix-synapse-rest-password-provider), where 3PID mappings would be

+- [Purpose](#purpose)
+- [Logs](#logs)
+  - [Locations](#locations)
+  - [Reading Them](#reading-them)
+  - [Common issues](#common-issues)
+- [Submit an issue](#submit-an-issue)
+
+## Purpose
+This document describes basic troubleshooting steps for ma1sd.
+
+## Logs
+### Locations
+ma1sd logs to `STDOUT` (Standard Output) and `STDERR` (Standard Error) only, which gets redirected
+to log file(s) depending on your system.
+
+If you use the [Debian package](install/debian.md), this goes to `syslog`.  
+If you use the [Docker image](install/docker.md), this goes to the container logs.  
+
+For any other platform, please refer to your package maintainer.
+
+### Increase verbosity
+To increase log verbosity and better track issues, the following means are available:
+- Add the `-v` command line parameter
+- Use the environment variable and value `MA1SD_LOG_LEVEL=debug`
+
+### Reading them
+Before reporting an issue, it is important to produce clean and complete logs so they can be understood.
+
+It is usually useless to try to troubleshoot an issue based on a single log line. Any action or API request
+in ma1sd would trigger more than one log lines, and those would be considered necessary context to
+understand what happened.
+
+You may also find things called *stacktraces*. Those are important to pin-point bugs and the likes and should
+always be included in any report. They also tend to be very specific about the issue at hand.
+
+Example of a stacktrace:
+```
+Exception in thread "main" java.lang.NullPointerException
+        at com.example.myproject.Book.getTitle(Book.java:16)
+        at com.example.myproject.Author.getBookTitles(Author.java:25)
+        at com.example.myproject.Bootstrap.main(Bootstrap.java:14)
+```
+
+### Common issues
+#### Internal Server Error
+`Contact your administrator with reference Transaction #123456789`
+
+This is a generic message produced in case of an unknown error. The transaction reference allows to easily find
+the location in the logs to look for an error.
+
+**IMPORTANT:** That line alone does not tell you anything about the error. You'll need the log lines before and after,
+usually including a stacktrace, to know what happened. Please take the time to read the surround output to get
+context about the issue at hand.
+
+## Submit an issue
+In case the logs do not allow you to understand the issue at hand, please submit clean and complete logs
+as explained [here](#reading-them) in a new issue on the repository, or [get in touch](../README.md#contact).
