 ## Settings
 
 ### Godot
 
-If you like this extension, you can set VS Code as your default script editor for Godot by following these steps:
-1. Open editor settings
-2. Select `Text Editor / External`
-3. Make sure the `Use External Editor` box is checked
-4. Fill `Exec Path` with the path to your VS Code executable
-5. Fill `Exec Flags` with `{project} --goto {file}:{line}:{col}`
+If you like this extension, you can set VS Code as your default script editor
+for Godot by following these steps:
+
+1. Open the **Editor Settings**

+5. Fill **Exec Flags** with `{project} --goto {file}:{line}:{col}`
 
 ### VS Code
 
 You can use the following settings to configure Godot Tools:
-- **GodotTools.godotVersion** - The Godot version of your project.
-- **GodotTools.editorPath** - The absolute path to the Godot executable. Required to run the project and test scenes directly from VS Code.
-- **GodotTools.workspaceDocumentWithMarkdown** - Control how the documentation of workspace symbols should be rendered: as plain text or as HTML from Markdown.
-- **GodotTools.ignoreIndentedVars** - Only parse variables defined on lines without an indentation.
-- **GodotTools.parseTextScene** - Parse a file as a Godot scene when the file name ends with `.tscn`.
-- **GodotTools.completeNodePath** - Show node paths within a workspace as part of code completion.
-- **GodotTools.godotProjectRoot** - Your Godot project's directory, which contains `project.godot` or `engine.cfg`.
 
-## Issues and Contributions
+- `editor_path` - The absolute path to the Godot editor executable.
+- `gdscript_lsp_server_port` - The WebSocket server port of the GDScript language server.
+- `check_status` - Check the GDScript language server connection status.
 
-The [Godot Tools](https://github.com/GodotExplorer/godot-tools) extension and  [engine modules](https://github.com/GodotExplorer/editor-server) are both hosted on GitHub. Feel free to open issues there and create pull requests anytime.

 ## FAQ
-   
-### Why isn't Intellisense showing up for me?
 
-Make sure you save your `.gd` file, then run "GodotTools: Update Workspace Symbols" from the Command Palette.
+### Why does it fail to connect to the language server?
 
-## TODO:
-* Convert official BBCode documentation into Markdown and render it into HTML with documentation previewer pages
-* Add mermaid support with documentation
-* Undefined variable checking
+- Godot 3.2 or later is required.
+- Make sure to open the project in the Godot editor first. If you opened
+  the editor after opening VS Code, you can click the **Retry** button
+  in the bottom-right corner in VS Code.
+
+### Why isn't IntelliSense displaying script members?
+
+- GDScript is a dynamically typed script language. The language server can't
+  infer all variable types.
+- To increase the number of results displayed, open the **Editor Settings**,
+  go to the **Language Server** section then check **Enable Smart Resolve**.
