 **Note:** When working with pull requests, keep the following in mind:
 * If you're working in the [shared repository model](/pull-requests/collaborating-with-pull-requests/getting-started/about-collaborative-development-models), we recommend that you use a topic branch for your pull request. While you can send pull requests from any branch or commit, with a topic branch you can push follow-up commits if you need to update your proposed changes.
-* When pushing commits to a pull request, don't force push. Force pushing changes the repository history and can corrupt your pull request. If other collaborators branch the project before a force push, the force push may overwrite commits that collaborators based their work on.
