+# Features
+
+## Document Symbol
+
+Document Symbol is a way to represent the structure of a document. They are used to provide a quick overview of the
+document and to allow for quick navigation.
+
+Ruby LSP already provides document symbols for Ruby files, such as classes, modules, methods, etc. But the Rails addon
+provides additional document symbols for Rails specific features.
+
+In VS Code, you can open the document symbols view by pressing `Ctrl + Shift + O`.
+
+### Active Record Callbacks, Validations, and Associations
+
+Navigates between Active Record callbacks, validations, and associations using the `Document Symbol` feature.

+
+## Go to Definition
+
+Go to definition is a feature that allows you to navigate to the definition of a symbol.
+
+In VS Code, you can trigger go to definition in 3 different ways:
+
+- Select `Go to Definition` from the context menu
+- `F12` on a symbol
+- `Cmd + Click` on a symbol
+
+In the following demos, we will use the `Cmd + Click` method to trigger go to definition.
+
+### Go to Active Record Callback and Validation Definitions
+
+Navigates to the definitions of Active Record callbacks and validations.

+## Ruby File Operations
+
+The Ruby LSP extension provides a `Ruby file operations` icon in the Explorer view that can be used to trigger
+the `Rails generate` and `Rails destroy` commands.
