+## Installation
+
+```sh
+git clone https://github.com/prettier/prettier-linter-helpers.git
+cd prettier-linter-helpers
+yarn install
+```
+
+## Running the tests
+
+```sh
+yarn run test
+```
+
+Linting is ran as part of `yarn run test`. The build will fail if there are any linting errors. You can run `yarn run lint --fix` to fix some linting errors (including formatting to match prettier's expectations). To run the tests without linting run `yarn run test`.
+
+## Publishing

+- Update `CHANGELOG.md` and commit.
+- Run the following:

+  ```sh
+  yarn publish
+  git push --follow-tags
+  ```
+
+  Running `yarn publish` shall:
+
+  - Bump the version in package.json (asking you for the new version number)
+  - Create a new commit containing that version bump in package.json
+  - Create a tag for that commit
+  - Publish to the npm repository

+  Running `git push --follow-tags` shall:
+
+  - Push the commit and tag to GitHub
