+# Contributing

+Thanks for contributing!
+
+## Installation
+
+```sh
+git clone https://github.com/ota-meshi/eslint-plugin-svelte.git
+cd eslint-plugin-svelte
+yarn
+```
+
+## Running the tests
+
+```sh
+yarn test
+```
+
+To run the tests with debugging log, you can use `yarn test:debug`.
+
+This is an [ESLint](http://eslint.org) plugin. Documentation for the APIs that it uses can be found on ESLint's [Working with Plugins](http://eslint.org/docs/developer-guide/working-with-plugins) page.
+
+This plugin is used to lint itself. The style is checked when `yarn lint` is run, and the build will fail if there are any linting errors. You can use `yarn lint-fix` to fix some linting errors.
+
