 Take away only one thing from this document, it should be this: Never, **EVER** make edits to the `staging` branch. ALWAYS make a new branch BEFORE you edit files. This is critical, because if your PR is not accepted, your copy of staging will be forever sullied and the only way to fix it is to delete your fork and re-fork.

 ## Common Steps
 1. Once the edits have been committed, you will be prompted to create a pull request on your fork's Github Page.
 2. By default, all pull requests should be against the FCC main repo, `staging` branch.
 3. Submit a [pull request](https://github.com/FreeCodeCamp/FreeCodeCamp/wiki/Pull-Request-Contribute) from your branch to Free Code Camp's `staging` branch.

    - **Do not add the issue number in the PR title**.
    - Examples: `Add Test Cases to Bonfire Drop It` `Correct typo in Waypoint Size Your Images`
 4. In the body of your PR include a more detailed summary of the changes you made and why.
-   - If the PR is meant to fix an existing bug/issue, then, at the end of your PR's commit message, append the keyword `closes` and #xxxx (where xxxx is the issue number). Example: `closes #1337`.
