+This module provides authproc-filters and authentication sources for interaction
+with LDAP directories.
+
+## Installation
+
+Once you have installed SimpleSAMLphp, installing this module is very simple.
+Just execute the following command in the root of your SimpleSAMLphp
+installation:
+
+```bash
+composer.phar require simplesamlphp/simplesamlphp-module-ldap:dev-master
+```
+
+where `dev-master` instructs Composer to install the `master` branch from the
+Git repository. See the [releases][releases]
+available if you want to use a stable version of the module.
+
+Next thing you need to do is to enable the module: in `config.php`,
+search for the `module.enable` key and set `ldap` to true:
+
+```php
+    'module.enable' => [
+         'ldap' => true,
+         …
+    ],
+```
