 Coding standard used by Shlink JavaScript projects.
+
+This library includes two ESLint configurations, the base one, and the react-specific one. Default export includes both:
+
+```js
+// eslint.config.js
+import shlink from '@shlinkio/eslint-config-js-coding-standard';
+
+export default shlink;
+```
+
+If the project does not use React, you can just use the base config:
+
+```js
+// eslint.config.js
+import { baseConfig } from '@shlinkio/eslint-config-js-coding-standard';
+
+export default baseConfig;
+```
