# How to Apply to the Platform

## Make changes

After the [initial installation and setup](https://ushahidi.gitbook.io/platform-developer-documentation/getting-started/setup_alternatives/setting-up-the-pattern-library-for-development) follow these instructions:

* Make sure gulp is running in your Terminal.
* Edit and save the appropriate Sass files.
* View your changes locally on localhost:8000 to see your styles in action.
* Commit your changes.

## Push changes to NPM

* *Assuming you have already committed your changes*
* Bump and tag a new version using npm version prerelease for a test release or npm version release for a production release
* Push the new version to npm using npm publish
* Finally, push the new tag to git using git push --tags origin

Note: The "version": "###" in pattern library package.json should stay in sync with the client package.json.

## Test your changes on a local client

* From within your platform-client installation run npm install ../platform-pattern-library/
* Run gulp in your platform-client install
* Check the results in the browser
