+# eslint-config-gitduck
+
+#### An [ESLint shareable config](https://eslint.org/docs/developer-guide/shareable-configs) for TypeScript that is based on [eslint-config-standard-with-typescript](https://github.com/standard/eslint-config-standard-with-typescript) and has GidDuck specific rules.
+
+[![JavaScript Style Guide - Standard Style](https://cdn.rawgit.com/standard/standard/master/badge.svg)](http://standardjs.com)
+
+## Usage
+
+Shareable configs are designed to work with the `extends` feature of `.eslintrc` files.
+You can learn more about
+[Shareable Configs](http://eslint.org/docs/developer-guide/shareable-configs) on the
+official ESLint website.
+
+Run the following command:
+
+```shell
+npm install --save-dev \
+  eslint@7 \
+  eslint-config-standard@14 \
+  eslint-plugin-standard@4 \
+  eslint-plugin-promise@4 \
+  eslint-plugin-import@2 \
+  eslint-plugin-node@11 \
+  eslint-plugin-react@7 \
+  typescript@3 \
+  @typescript-eslint/eslint-plugin@3 \
+  @typescript-eslint/parser@3 \
+  eslint-config-standard-with-typescript@18 \
+  github:gitduckhq/eslint-config-gitduck
+```
+
+Here is an example `.eslintrc.js`:
+
+```javascript
+module.exports = {
+  extends: 'gitduck',
+  parser: '@typescript-eslint/parser',
+  parserOptions: {
+    project: './tsconfig.json',
+  },
+  plugins: [
+    '@typescript-eslint',
+  ],
+}
+```
+
+*Note: The `eslint-config-` prefix in `extends` is omitted since it is automatically assumed by ESLint.*
+
+You can override settings from the shareable config by adding them directly into this file.
