+# ESLint Plugin
+
+Lingui provides an ESLint plugin to help you find common Lingui usage errors in your code.
+
+## Installation
+
+You'll first need to install [ESLint](http://eslint.org):
+
+```bash npm2yarn
+npm install --save-dev eslint
+```
+
+Next, install `eslint-plugin-lingui`:
+
+```bash npm2yarn
+npm install --save-dev eslint-plugin-lingui
+```
+
+**Note:** If you installed ESLint globally (using the `-g` flag) then you must also install `eslint-plugin-lingui` globally.
+
+## Usage
+
+Add `lingui` to the plugins section of your `.eslintrc` configuration file. You can omit the `eslint-plugin-` prefix:
+
+```json
+{
+ "plugins": ["lingui"]
+}
+```
+
+:::info
+See the [official repository](https:/lingui/eslint-plugin#usage) for more information on the rules.
