 ## Get a Fork ready
 
-You can get your own fork by using the button or clicking [this](https://github.com/FreeCodeCamp/wiki/new/master?readme=1#fork-destination-box).
-Once you get a fork, you will clone it with `git clone url` where `url` is the link to your fork.
+1. Fork it: You can get your own fork of our wiki by using the button or clicking [this](https://github.com/FreeCodeCamp/wiki/new/master?readme=1#fork-destination-box).
 
-Once that is done, you can start contributing by checking our [issues](https://github.com/FreeCodeCamp/wiki/issues) and creating nee pull requests.

+
+2. Once you have forked the repository, you will clone it with:
+
+  ```sh
+  $git clone https://github.com/YOUR-USERNAME/wiki.git
+  ```
+
+  This will make a local copy on your machine.
+
+3. Add the remote: You will need a way to keep your fork synchronized with the original repository. The following command will show you **verbose** list of the current remotes you have.
+
+  ```sh
+  $git remote -v
+  origin  https://github.com/YOUR_USERNAME/wiki.git (fetch)
+  origin  https://github.com/YOUR_USERNAME/wiki.git (push)
+  ```
+
+  This means there is no remote pointing to the original repository you forked from. You would add it with:
+
+  ```sh
+  $git remote add upstream https://github.com/FreeCodeCamp/wiki.git
+  ```
+
+  This will create a new remote named **upstream**. You can verify the changes with `git remote -v`
+
+  ```sh
+  $git remote -v
+  origin    https://github.com/YOUR_USERNAME/wiki.git (fetch)
+  origin    https://github.com/YOUR_USERNAME/wiki.git (push)
+  upstream  https://github.com/FreeCodeCamp/wiki.git (fetch)
+  upstream  https://github.com/FreeCodeCamp/wiki.git (push)
+  ```
+
+4. Sync the fork when needed: After another PR has been merged, you will need to fetch the changes and rebase your work.
+
+  ```sh
+  $git fetch --all --prune # fetch all remote repos and delete any deleted branches
+  $git checkout master # switch to `master` branch
+  $git rebase --preserve-merges upstream/master # preserve merge commits while rebasing
+  ### or better
+  $git reset --hard upstream/master # SAFE! to do as `master` branch shouldn't be committed to directly
+  $git push origin master # push changes to your forked wiki repo
+  ```
+
+5. Once you have completed these steps, you can start contributing by checking our [issues](https://github.com/FreeCodeCamp/wiki/issues) and creating new pull requests.
