+# LSP Example
+
+Heavily documented sample code for https://code.visualstudio.com/docs/extensions/example-language-server.
+
+## 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
+```
+
+## Compile and Run
+
+- 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 compile the client and server.
+- Switch to the Debug viewlet.
+- Select `Launch Client` from the drop down.
+- Run the lauch config.
+- If you want to debug the server as well use the launch configuration `Attach to Server`
+- In the [Extension Development Host] 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.

+# Welcome to your VS Code Extension
+
+## What's in the folder
+* This folder contains all of the files necessary for your extension.
+* `package.json` - this is the manifest file in which you declare your language support and define
+the location of the grammar file that has been copied into your extension.
+* `syntaxes/elm.tmLanguage` - this is the Text mate grammar file that is used for tokenization.
+* `language-configuration.json` - this the language configuration, defining the tokens that are used for
+comments and brackets.
+
+## Get up and running straight away
+* Make sure the language configuration settings in `language-configuration.json` are accurate.
+* Press `F5` to open a new window with your extension loaded.
+* Create a new file with a file name suffix matching your language.
+* Verify that syntax highlighting works and that the language configuration settings are working.
+
+## Make changes
+* You can relaunch the extension from the debug toolbar after making changes to the files listed above.
+* You can also reload (`Ctrl+R` or `Cmd+R` on Mac) the VS Code window with your extension to load your changes.
+
+## Add more language features
+* To add features such as intellisense, hovers and validators check out the VS Code extenders documentation at
+https://code.visualstudio.com/docs
+
+## Install your extension
+* To start using your extension with Visual Studio Code copy it into the `<user home>/.vscode/extensions` folder and restart Code.
+* To share your extension with the world, read on https://code.visualstudio.com/docs about publishing an extension.
