+
+## Issue Reporting Guidelines
+
+- The issue list of this repo is **exclusively** for bug reports and feature requests. Non-conforming issues will be closed immediately.
+
+- Try to search for your issue, it may have already been answered or even fixed in the master branch.
+
+- Check if the issue is reproducible with the latest stable version of rollup-plugin-vue-i18n. If you are using a pre-release, please indicate the specific version you are using.
+
+- It is **required** that you clearly describe the steps necessary to reproduce the issue you are running into. Issues with no clear repro steps will not be triaged. If an issue labeled `Status: Need More Info` receives no further input from the issue author for more than 5 days, it will be closed.
+
+- For bugs that involves build setups, you can create a reproduction repository with steps in the README.
+
+- If your issue is resolved but still open, don’t hesitate to close it. In case you found a solution by yourself, it could be helpful to explain how you fixed it.
+
+## Pull Request Guidelines
+
+- Checkout a topic branch from the `master` branch.
+
+- It's OK to have multiple small commits as you work on the PR - we will let GitHub automatically squash it before merging.
+
+- Make sure `npm test` passes. (see [development setup](#development-setup))
+
+- If adding new feature:
+  - Add accompanying test case.
+  - Provide convincing reason to add this feature. Ideally you should open a suggestion issue first and have it greenlighted before working on it.
+
+- If fixing a bug:
+  - Provide detailed description of the bug in the PR.
+  - Add appropriate test coverage if applicable.
+
+### Work Step Example
+- Fork the repository from [intlify/rollup-plugin-vue-i18n](https://github.com/intlify/rollup-plugin-vue-i18n) !
+- Create your topic branch from `master`: `git branch my-new-topic origin/master`
+- Add codes and pass tests !
+- Commit your changes: `git commit -am 'Add some topic'`
+- Push to the branch: `git push origin my-new-topic`
+- Submit a pull request to `master` branch of `intlify/rollup-plugin-vue-i18n` repository !
+
+## Development Setup
+
+After cloning the repo, run:
+
+    $ npm install
+
+### Commonly used NPM scripts
+
+    # lint source codes
+    $ npm run lint
+
+    # run the full test suite, include linting
+    $ npm test
+
+There are some other scripts available in the `scripts` section of the `package.json` file.
+
+The default test script will do the following: lint with ESLint -> unit tests with coverage. **Please make sure to have this pass successfully before submitting a PR.** Although the same tests will be run against your PR on the CI server, it is better to have it working locally beforehand.
