-This bot provides a two-step-registration for matrix ([synapse](https://github.com/matrix-org/synapse)).
+This bot provides a two-step-registration for matrix.

 This is done in several steps:
- potential new user registers on a bot-provided site
- user has to verify its mail address
- bot sends a message to predefined room with a registration notification.
+- potential new user registers on a bot-provided side
+- bot sends a message to prefined room with a registration notification.
 - users in that room now can approve or decline the registration.
- When approved
-  - the bot creates short time credentials
-  - sends them to the user
-  - stores them encrypted in own databas or uses that as initial password for registration
-
-There are two operation modes available:
- `operationMode=synapse`
-    - No adjustments on your running environment are required. This bot uses the the [Shared-Secret Registration of synapse](https://github.com/matrix-org/synapse/blob/master/docs/admin_api/register_api.rst) to register the users.
- `operationMode=local`:
-    - Bot handles user management. Therefore it stores the user-data and uses [matrix-synapse-rest-auth](https://github.com/kamax-io/matrix-synapse-rest-auth#integrate) to authenticate the users.
-    - This way it is possible to set the display name of a user on first login (first- and lastname instead of username)
-    - The email address of the user can be used to implement third party lookup (requires [mxisd](https://github.com/kamax-io/mxisd/blob/master/docs/stores/rest.md))
-    - search for users you have not seen yet but are available on the server
-
-## Requirements
-
- Working PHP environment with
-  - database connection provider \[one of sqlite, mysql, postgres\]
-  - curl extension
-  - mail capability to interact with the users (verification, approval (+ initial password), notifications)
-      - either via sendmail or with credentials
- [composer](https://getcomposer.org) installed
- [matrix-synapse-rest-auth](https://github.com/kamax-io/matrix-synapse-rest-auth) when using `operationMode=local`
-
-## How to install
-
-```
-git clone https://github.com/krombel/matrix-register-bot
-cd matrix-register-bot
-composer install
-cp config.sample.php config.php
-editor config.php
-```
- Configure your webserver to have the folder `public` accessible via web.
-
-
-When running `operationMode=local`:
- Configure your webserver to provide the folder `internal` internally. This is only meant to be accessible by mxisd and matrix-synapse-rest-auth 
- To integrate with [matrix-synapse-rest-auth](https://github.com/kamax-io/matrix-synapse-rest-auth):
-  - `/_matrix-internal/identity/v1/check_credentials` should map to `internal/login.php`
- To integrate with [mxisd](https://github.com/kamax-io/mxisd): Have a look at [the docs of mxisd](https://github.com/kamax-io/mxisd/blob/master/docs/stores/rest.md) and apply as follows:
-
-
-| Key                            | file which handles that       | Description                                          |
-|--------------------------------|-------------------------------|------------------------------------------------------|
-| rest.endpoints.auth            | internal/login.php            | Validate credentials and get user profile            |
-| rest.endpoints.directory       | internal/directory_search.php | Search for users by arbitrary input                  |
-| rest.endpoints.identity.single | internal/identity_single.php  | Endpoint to query a single 3PID                      |
-| rest.endpoints.identity.bulk   | internal/identity_bulk.php    | Endpoint to query a list of 3PID                     |
-
-
-## Further notes:
-
-### Security: Passwords from registration form are stored in clear text
-Currently the passwords which are typed in while capturing the register request are stored in clear text.
-The bot needs to access them to trigger a register request with correct credentials.
-It is currently strongly recommended to set `"getPasswordOnRegistration" => false` in your config!
-This leads to autocreating passwords which will then be send to the users directly without storing it.
-
-### Use the ChangePasswortInterceptor (if `operationMode=local`)
-
-To allow users to change their pasword you need a reverse proxy which maps `/_matrix/client/r0/account/password` to `internal/intercept_change_password.php`.
-Here is an example for nginx:
-```
-        location /_matrix/client/r0/account/password {
-                proxy_pass http://localhost/mxbot/internal/intercept_change_password.php;
-                proxy_set_header X-Forwarded-For $remote_addr;
-        }
-```
-### The bot postpones some actions
-There is a cron.php which implements retries and database cleanups (e.g. to remove a username claim)
-For this run cron.php regularly with your system of choice.
-A suggested interval is once per day
+- The bot then uses the registration token to register the user or just drops the registration request.
