-# Theia - TSLint Extension
-
-See [here](https://www.theia-ide.org/doc/index.html) for a detailed documentation.
-
-## Configuring the tslint-server-plugin
-
-You can define settings for the `tslint-language-service` plugin in the `tsconfig.json` file.
-The available settings are documented [here](https://github.com/angelozerr/tslint-language-service#configuration-options):
-```json
-{
-    "compilerOptions": {
-        "plugins": [
-            {
-                "name": "tslint-language-service",
-                "alwaysShowRuleFailuresAsWarnings": false,
-                "ignoreDefinitionFiles": true
-                //"configFile": "../tslint.json",
-                //"disableNoUnusedVariableRule": false
-            }
-        ],
-    }
-}
-```
-
-## Using a different version of tslint than the version that is bundled with the extension
-
-The extension comes with a particular version of tslint.
-If you want to use a different version then you have to install the `tslint-languageservice` package and `tslint` as a peer to the TypeScript version you want to use.
-The modules folder should have the following layout:
-- node_modules
-  - typescript
-  - tslint
-  - tslint-language-service
