 ### Managing enman repositories
 
+Install an available SCR repository using enman. The title is taken to be the
+repository name by default, and must be available via enman. Use an `ensure`
+value of `present` to install the repo, and `absent` to remove it.
+
 ```puppet
 enman_repo { 'community':
   ensure => present,
 }
 ```
 
+### Enabling and disabling entropy repositories
+
+Installed repositories (whether system or SCR repositories) can be enabled and
+disabled using the `entropy_repo` type. 
+
+To enable a repository, use:
+```puppet
+entropy_repo { 'sabayon-limbo':
+  enabled => 'true',
+}
+```
+
+To disable a repository (only if present), use:
+```puppet
+if 'sabayon-limbo' in $facts['entropy_repos'] {
+  entropy_repo { 'sabayon-limbo':
+    enabled => 'false',
+  }
+}
+```
+
+This type cannot currently install or remove repositories, only control the
+enabled state of existing repositories. The repository being managed must
+already exist on the system.

 ### Facts
 
+#### `entropy_repos`
+
+Provides a structured fact identifying the entropy repos present on the system
+including their enabled/disabled state, and whether they are enman or entropy
+repositories.
+
+Example (in yaml format for readability):
+```yaml
+---
+sabayonlinux.org:
+  repo_type: "entropy"
+  enabled: "true"
+sabayon-limbo:
+  repo_type: "entropy"
+  enabled: "false"
+community:
+  repo_type: "enman"
+  enabled: "true"
+```
+
 #### `locale`
 
 Identifies the system-wide default locale, as set by `eselect`.
