Notes

It is highly recommended that the Rails documentation is generated in order to have an offline Rails API reference. Do the following to create the API reference:

1. In your home directory run this command – rails new sample_app
2. Navigate to the newly created directory
3. Run the following command to generate the documentation – rake doc:rails
4. Move the generated documentation from doc/api to your Documents directory
5. Rename the moved documentation directory to rails-3.2.3-api-doc
6. In the rails-3.2.3-api-doc directory create a shortcut to index.html on your desktop, or view index.html in the web browser and bookmark it
