 # Drupal Module Generator (dmg)
 
-A scaffolding tool for generating new modules for Drupal 7 and 8.
+A scaffolding tool for generating new modules for Drupal 7 and (soon) 8.
+
+[Watch a short demo][demo].
+
+[demo]: https://opdavi.es/6i3YZ 'A short demo video on YouTube'
+
+## Installation
+
+The Drupal Module Generator is installed via [Composer][]:
+
+```bash
+composer global require opdavies/drupal-module-generator
+```
+
+[composer]: https://getcomposer.org
 
 ## Usage
 
-TODO
+### Drupal 7
+
+```bash
+dmg generate:drupal-7-module {name}
+```
+
+Generated Drupal 7 modules contain the appropriately named `.info` and `.module` files,
+as well as a test case located in `src/Tests/Functional` which [is loaded automatically](https://www.oliverdavies.uk/articles/psr4-autoloading-test-cases-drupal-7).
