+The playbook can now help you set up [matrix-registration](https://github.com/ZerataX/matrix-registration) - an application that lets you keep your Matrix server's registration private, but still allow certain users (those having a unique registration link) to register by themselves.

+See our [Setting up matrix-registration](docs/configuring-playbook-matrix-registration.md) documentation page to get started.

+# Setting up matrix-registration (optional)
+
+The playbook can install and configure [matrix-registration](https://github.com/ZerataX/matrix-registration) for you.
+
+> matrix-registration is a simple python application to have a token based matrix registration.
+
+Use matrix-registration to **create unique registration links**, which people can use to register on your Matrix server. It allows you to **keep your server's registration closed (private)**, but still allow certain people (these having a special link) to register a user account.
+
+**matrix-registration** provides 2 things:
+
+- **an API for creating registration tokens** (unique registration links). This API can be used via `curl` or via the playbook (see [Usage](#usage) below)
+
+- **a user registration page**, where people can use these registration tokens. By default, exposed at `https:///matrix.DOMAIN/matrix-registration`
+
+
+## Installing
+
+Adjust your playbook configuration (your `inventory/host_vars/matrix.DOMAIN/vars.yml` file):
+
+```yaml
+matrix_registration_enabled: true
+
+# Generate a strong secret using: `pwgen -s 64 1`.
+matrix_registration_admin_secret: "ENTER_SOME_SECRET_HERE"
+```
+
+Then, run the [installation](installing.md) command again:
+
+```
+ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start
+```
+
+
+## Usage
+
+**matrix-registration** gets exposed at `https:///matrix.DOMAIN/matrix-registration`
+
+It provides various [APIs](https://github.com/ZerataX/matrix-registration/wiki/api) - for creating registration tokens, listing tokens, disabling tokens, etc. To make use of all of its capabilities, consider using `curl`.
+
+We make the most common API (the one for creating unique registration tokens) easy to use via the playbook.
+
+**To create a new user registration token (link)**, use this command:
+
+```
+ansible-playbook -i inventory/hosts setup.yml \
+--tags=generate-matrix-registration-token \
+--extra-vars="one_time=yes ex_date=2021-12-31"
+```
+
+The above command creates and returns a **one-time use** token, which **expires** on the 31st of December 2021.
+Adjust the `one_time` and `ex_date` variables as you see fit.
+
+Share the unique registration link (generated by the command above) with users to let them register on your Matrix server.
