-# File replace
+# File Replace
 
-This small utility module allows users with the right permissions to replace
-files.
+The file replace module is a small utility providing site administrators with
+the possibility to replace files, keeping the file uri intact. This is useful
+in cases where a file is linked or used directly but needs to be updated
+occasionally.
+
+For a full description of the module, visit the
+[Project Page](https://www.drupal.org/project/file_replace).

+
+## Requirements
+
+This module requires no modules outside of Drupal core.
+
+
+## Installation
+
+Install as you would normally install a contributed Drupal module. For further
+information, see
+[Installing Drupal Modules](https://www.drupal.org/docs/extending-drupal/installing-drupal-modules).
+
+
+## Configuration
+
+The module currently only provides a 'Replace' page for files. You will need
+to manually add links to the file overview page. Simply adding a global text
+field with a link like the following would work fine:
+```
+admin/content/files/replace/{{ fid }}
+```
