+## Exposed variables for use in other roles
+
+You will likely want to use various ruby related commands in other roles. This role exposes a number of popular paths for easy access.
+
+- `ruby_rvm`:
+    - The path to the rvm binary
+
+- `ruby_rvm_default_wrappers`:
+    - The path containing all of the wrapped ruby related binaries
+
+- `ruby`:
+    - The path to the ruby binary
+
+- `ruby_gem`:
+    - The path to the gem binary
+
+- `ruby_bundle`:
+    - The path to the bundle binary
+
+- `ruby_rake`:
+    - The path to the rake binary with bundle exec already applied
+
+### Example
+
+If you wanted to run a database migration in rails you would use `{{ ruby_rake }} db:migrate`.
