+# LSP Example
+
+Heavily documented sample code for https://code.visualstudio.com/api/language-extensions/language-server-extension-guide
+
+## Functionality
+
+This Language Server works for plain text file. It has the following language features:
+- Completions
+- Diagnostics regenerated on each file change or configuration change
+
+It also includes an End-to-End test.
+
+## Structure
+
+```
+.
+├── client // Language Client
+│   ├── src
+│   │   ├── test // End to End tests for Language Client / Server
+│   │   └── extension.ts // Language Client entry point
+├── package.json // The extension manifest.
+└── server // Language Server
+    └── src
+        └── server.ts // Language Server entry point
+```
+
+## Running the Sample
+
+- Run `npm install` in this folder. This installs all necessary npm modules in both the client and server folder
+- Open VS Code on this folder.
+- Press Ctrl+Shift+B to start compiling the client and server in [watch mode](https://code.visualstudio.com/docs/editor/tasks#:~:text=The%20first%20entry%20executes,the%20HelloWorld.js%20file.).
+- Switch to the Run and Debug View in the Sidebar (Ctrl+Shift+D).
+- Select `Launch Client` from the drop down (if it is not already).
+- Press ▷ to run the launch config (F5).
+- In the [Extension Development Host](https://code.visualstudio.com/api/get-started/your-first-extension#:~:text=Then%2C%20inside%20the%20editor%2C%20press%20F5.%20This%20will%20compile%20and%20run%20the%20extension%20in%20a%20new%20Extension%20Development%20Host%20window.) instance of VSCode, open a document in 'plain text' language mode.
+  - Type `j` or `t` to see `Javascript` and `TypeScript` completion.
+  - Enter text content such as `AAA aaa BBB`. The extension will emit diagnostics for all words in all-uppercase.
