FreeCodeCamp Pull Request template

Please, go through these steps before you submit a PR.

1. Make sure that your PR is not a duplicate.
2. If not, then make sure that:

2.1. You have done your changes in a separate branch. Branches MUST have descriptive names that start with either the fix/ or feature/ prefixes. Good examples are: fix/signin-issue or feature/issue-templates.

2.2. You have a descriptive commit message with a short title (first line).

2.3. You have only one commit (if not, squash them into one commit).

2.4. npm test doesn't throw any error. If it does, fix them first and amend your commit (git commit --amend).

3. After these steps, you're ready to open a pull request.

3.1. Your pull request MUST NOT target the master branch on FreeCodeCamp's repository. You probably want to target staging instead.

3.2. Give a descriptive title to your PR.

3.3. Provide a description of your changes.

3.4. Put closes #XXXX in your comment to auto-close the issue that your PR fixes (if such).

IMPORTANT: Please review the CONTRIBUTING.md file for detailed contributing guidelines.
