+Translating Rails Guides
+------------------------
+
+We are happy to have people volunteer to translate the Rails guides into their own language.
+If you want to translate the Rails guides in your own language, follows these steps:
+
+* Fork the project (rails/rails).
+* Add a source folder for your own language, for example: *guides/source/it-IT* for Italian.
+* Copy the contents of *guides/source* into your own language directory and translate them.
+* Do NOT translate the HTML files, as they are automatically generated.
+
+To generate the guides in HTML format cd into the *guides* direcotry then run (eg. for it-IT):
+
+```bash
+$ bundle install
+$ bundle exec rake guides:generate:html GUIDES_LANGUAGE=it-IT
+```
+
+This will generate the guides in an *output* directory.
+
+NOTE: The instructions are for Rails > 4. The Redcarpet Gem doesn't work with JRuby.
+
+Translation efforts we know about (various versions):
