+intro: A fork is a copy of a repository. Forking a repository allows you to freely experiment with changes without affecting the original project.
+versions:
+  free-pro-team: '*'
+  enterprise-server: '*'
+---
+
+Most commonly, forks are used to either propose changes to someone else's project or to use someone else's project as a starting point for your own idea.
+
+#### Propose changes to someone else's project
+
+For example, you can use forks to propose changes related to fixing a bug. Rather than logging an issue for a bug you've found, you can:
+
+- Fork the repository.
+- Make the fix.
+- Submit a pull request to the project owner.
+
+#### Use someone else's project as a starting point for your own idea.
+
+Open source software is based on the idea that by sharing code, we can make better, more reliable software. For more information, see the "[About the Open Source Initiative](http://opensource.org/about)" on the Open Source Initiative.
+
+When creating your public repository from a fork of someone's project, make sure to include a license file that determines how you want your project to be shared with others. For more information, see "[Choose an open source license](http://choosealicense.com/)" at choosealicense.

+**Tip**: You can also fork a repository using the {{ site.data.variables.product.prodname_cli }}. For more information, see "[`gh repo fork`](https://cli.github.com/manual/gh_repo_fork)" in the {{ site.data.variables.product.prodname_cli }} documentation.

+
+### Fork an example repository
+
+Forking a repository is a simple two-step process. We've created a repository for you to practice with.
+
+1. On {{ site.data.variables.product.product_location }}, navigate to the [octocat/Spoon-Knife](https://github.com/octocat/Spoon-Knife) repository.
+2. In the top-right corner of the page, click **Fork**.
+![Fork button](/assets/images/help/repository/fork_button.jpg)
+
+### Keep your fork synced
+
+You might fork a project to propose changes to the upstream, or original, repository. In this case, it's good practice to regularly sync your fork with the upstream repository. To do this, you'll need to use Git on the command line. You can practice setting the upstream repository using the same [octocat/Spoon-Knife](https://github.com/octocat/Spoon-Knife) repository you just forked.
+
+#### Step 1: Set up Git
+
+If you haven't yet, you should first [set up Git](/articles/set-up-git). Don't forget to [set up authentication to {{ site.data.variables.product.product_location }} from Git](/articles/set-up-git#next-steps-authenticating-with-github-from-git) as well.
+
+#### Step 2: Create a local clone of your fork
+
+Right now, you have a fork of the Spoon-Knife repository, but you don't have the files in that repository on your computer. Let's create a clone of your fork locally on your computer.
+
+1. On {{ site.data.variables.product.product_name }}, navigate to **your fork** of the Spoon-Knife repository.
+{{ site.data.reusables.repositories.copy-clone-url }}
+{{ site.data.reusables.command_line.open_the_multi_os_terminal }}
+{{ site.data.reusables.command_line.change-current-directory-clone }}
+4. Type `git clone`, and then paste the URL you copied earlier. It will look like this, with your {{ site.data.variables.product.product_name }} username instead of `YOUR-USERNAME`:
+  ```shell
+  $ git clone https://{{ site.data.variables.command_line.codeblock }}/<em>YOUR-USERNAME</em>/Spoon-Knife
+  ```
+
+5. Press **Enter**. Your local clone will be created.
+  ```shell
+  $ git clone https://{{ site.data.variables.command_line.codeblock }}/<em>YOUR-USERNAME</em>/Spoon-Knife
+  > Cloning into `Spoon-Knife`...
+  > remote: Counting objects: 10, done.
+  > remote: Compressing objects: 100% (8/8), done.
+  > remove: Total 10 (delta 1), reused 10 (delta 1)
+  > Unpacking objects: 100% (10/10), done.
+  ```
+
+Now, you have a local copy of your fork of the Spoon-Knife repository.
+
+#### Step 3: Configure Git to sync your fork with the original Spoon-Knife repository
+
+When you fork a project in order to propose changes to the original repository, you can configure Git to pull changes from the original, or upstream, repository into the local clone of your fork.
+
+1. On {{ site.data.variables.product.product_name }}, navigate to the [octocat/Spoon-Knife](https://github.com/octocat/Spoon-Knife) repository.
+{{ site.data.reusables.repositories.copy-clone-url }}
+{{ site.data.reusables.command_line.open_the_multi_os_terminal }}
+4. Change directories to the location of the fork you cloned in [Step 2: Create a local clone of your fork](#step-2-create-a-local-clone-of-your-fork).
+    - To go to your home directory, type just `cd` with no other text.
+    - To list the files and folders in your current directory, type `ls`.
+    - To go into one of your listed directories, type `cd your_listed_directory`.
+    - To go up one directory, type `cd ..`.
+5. Type `git remote -v` and press **Enter**. You'll see the current configured remote repository for your fork.
+  ```shell
+  $ git remote -v
+  > origin  https://{{ site.data.variables.command_line.codeblock }}/<em>YOUR_USERNAME</em>/<em>YOUR_FORK</em>.git (fetch)
+  > origin  https://{{ site.data.variables.command_line.codeblock }}/<em>YOUR_USERNAME</em>/<em>YOUR_FORK</em>.git (push)
+  ```
+
+6. Type `git remote add upstream`, and then paste the URL you copied in Step 2 and press **Enter**. It will look like this:
+  ```shell
+  $ git remote add upstream https://{{ site.data.variables.command_line.codeblock }}/octocat/Spoon-Knife.git
+  ```
+
+7. To verify the new upstream repository you've specified for your fork, type `git remote -v` again. You should see the URL for your fork as `origin`, and the URL for the original repository as `upstream`.
+  ```shell
+  $ git remote -v
+  > origin    https://{{ site.data.variables.command_line.codeblock }}/<em>YOUR_USERNAME</em>/<em>YOUR_FORK</em>.git (fetch)
+  > origin    https://{{ site.data.variables.command_line.codeblock }}/<em>YOUR_USERNAME</em>/<em>YOUR_FORK</em>.git (push)
+  > upstream  https://{{ site.data.variables.command_line.codeblock }}/<em>ORIGINAL_OWNER</em>/<em>ORIGINAL_REPOSITORY</em>.git (fetch)
+  > upstream  https://{{ site.data.variables.command_line.codeblock }}/<em>ORIGINAL_OWNER</em>/<em>ORIGINAL_REPOSITORY</em>.git (push)
+  ```
+
+Now, you can keep your fork synced with the upstream repository with a few Git commands. For more information, see "[Syncing a fork](/articles/syncing-a-fork)."
+
+#### Next steps
+
+You can make any changes to a fork, including:
+
+- **Creating branches:** [*Branches*](/articles/creating-and-deleting-branches-within-your-repository/) allow you to build new features or test out ideas without putting your main project at risk.
+- **Opening pull requests:** If you are hoping to contribute back to the original repository, you can send a request to the original author to pull your fork into their repository by submitting a [pull request](/articles/about-pull-requests).
