 # Embargoes
-Drupal 8 module for managing embargo policies with access restrictions on content
+
+# Introduction
+
+Adds the ability to manage embargo policies with access restrictions on content.
 
 ## Requirements
-Embargoes requires no other Drupal modules to work.
+
+This module requires the following modules/libraries:
+
+* [Menu UI](https://www.drupal.org/docs/core-modules-and-themes/core-modules/menu-ui-module)
+
+## Installation
+
+Install as
+[usual](https://www.drupal.org/docs/8/extending-drupal-8/installing-drupal-8-modules).
+
+## Configuration
+
+Configuration options can be set at `admin/config/content/embargoes/settings`,
+including notification options and IP range settings that can apply to
+embargoes.
+
+To add an IP range for use on embargoes, navigate to
+`admin/config/content/embargoes/settings/ips` and click 'Add IP range'. Ranges
+created via this method can then be used as IP address whitelists when creating
+embargoes.
+
+## Usage
+
+### Applying an embargo
+
+An embargo can be applied to an existing node by navigating to
+`node/{node_id}/embargoes`. From here, an embargo can be applied if it doesn't
+already exist, and existing embargoes can be modified or removed.
+
+### Logging
+
+Embargo logs are kept at `admin/config/content/embargoes/settings/log`,
+including who created the embargo, or how it was changed.
+
