+In VS Code, open the branch menu from the bottom left (see {numref}`git-branch-menu-main`). You'll be be greeted with a menu that looks like the one in {numref}`git-branch-selection-menu`. In this menu, we get an overview of the branches of our repository. Notice that our new branch `chapter-2` appears as `origin/chapter-2`, and has a cloud icon in front of it. This means that the branch only exists on the remote repository. 
+
+Check out the branch by simply clicking on it. Check that the branch is indeed checked out by looking at the branch menu button in the bottom left again; it should now say the name of your branch instead of `main` (in our case `chapter-2`).

-**by updating your repository (pulling) and creating your own version (branching) or select existing version (checkout branch) with ...**
+Since you are working in a repositery with multiple colleagues, it is good practice to make sure your local repositery is up to date before you start branching. This is especially important when you want to work in an existing branch. In that case you want to make sure that the existing branch shows in your local repositery. Therefore, you first need to pull all the changes from the remote repositery to your local repositery.  
+
+This synchronizes the remote repositery with your local repositery on your computer. Click on `Fetch` in the top bar. Then on the same place, click on 'Pull'.

+
+**2. Create your own version by creating a new branch.**
+
+Although it is possible to create new branches in GitHub Desktop directly, creating new branches on the remote repositery (on GitLab or GitHub) is better for collaborating because the new branch becomes immediately visible to everyone working in the repositery as opposed to becoming visible after being pushed to the remote repositery.

+2. A new page opens ({numref}`new-branch-menu`), on which you can specify the name of your branch and the source branch. Try to think of a good name for your branch. For example, `chapter-2` is a suitable name if we're going to be working on Chapter 2 of our book. After you've made sure that the selected source branch is correct, click "Create branch".

 We have previously introduced the notions of using Git in the online environment (remote) or locally. All the (text, figures, etc.) files that make up the book are contained on the remote repository on GitLab or GitHub. This could be on an open repository on `gitlab.com` or `github.com`.

+1. Make sure that you've committed all your new sections and changes, and that they're pushed to the remote repository.
 
+2. In GitHub, navigate to the repositery you want to work in. In the top bar click `Pull Requests`. Then, in the new window click on `New Pull Request`. 
+
+<figure align="center">
+    <img src="figures/Pull_Request.PNG" alt="Example Image" width="650">
+</figure>
+
+3. You can now choose a base branch and a compare branch. 
+
+- Base Branch: The base branch is the branch into which you want to merge your changes.
+- Compare Branch: The compare branch, also known as the "head" branch, is the branch that contains the changes you want to merge into the base branch.
+
+<figure align="center">
+    <img src="figures/Pull_Request2.PNG" alt="Example Image" width="650">
+</figure>
+
+In the figure, you can see that we want to merge our changes from the branch `merge_conflict` *into* `main`, `merge_conflict` is the compare branch and `main` is the base branch. Note that in the figure it says that the branches cannot be automatically merged. The reason for this is that there are conflicts in the two branches, which you can see when scrollong down. 
+
+You can still create the pull request but you will have to manage the conflicts. Once you've selected the correct branches, click `View Pull Request`.
+
+4. As previously mentioned, before merging the two branches we have to resolve the conflicts. Click on 'Resolve conflicts`. Note that if your branches do not have conflicting changes you can merge directly and skip this step.
+
+<figure align="center">
+    <img src="figures/Pull_Request3.PNG" alt="Example Image" width="650">
+</figure>
+
+Clicking on 'Resolve conflicts`, will open the conflicted files in the text editor. There you can manually edit the files to the version you would like to retain. 
+
+<figure align="center">
+    <img src="figures/Pull_Request4.PNG" alt="Example Image" width="650">
+</figure>
+
+Once you are done, click on `mark as resolved` in the top right of the window. Do this for all conflicted files. 
+In case you have cloned the repositery you can also resolve the conflicts locally using VS Code for example. You can read more about it [here](edit_book.md#... GitHub Desktop)
+
+5. Commit the changes by clicking on `Commit merge`. 
+
+<figure align="center">
+    <img src="figures/Pull_Request5.PNG" alt="Example Image" width="650">
+</figure>
+
+6. You can now complete the pull request by clicking `merge pull request`.

+# Open files online / clone files
+We have previously introduced the notions of using Git in the online environment (remote) or locally. All the (markdown) files that make up the book are contained on the remote repository on GitLab or GitHub. This could be on an open repository on `gitlab.com` or `github.com`. In the context of creating educational books for students at TU Delft, the repository will most likely be located on `gitlab.tudelft.nl`.
+
+If you'd like to work on your book locally (on your device, perhaps using Jupyter Lab or VS Code), you need to clone your repositery from the remote to your device. In familiar words, this means you need to make a copy of your book on your laptop.
+
+### Cloning a repository
+
+You can clone a repositery from GitLab and GitHub using GitHub Desktop or you can clone it with Git in VS Code.
+
+`````{tab-set}
+````{tab-item} Clone from GitLab using GitHub Desktop
+
+1. On GitLab, go to the repository of your book. Click on the blue button that says "Clone" or "Code", and copy the link under "Clone with SSH".
+
+```{figure} ../images/gitlab-clone.png
+:name: gitlab-clone
+
+The cloning menu.
+```
+2. Navigate to GitHub Desktop (which you've previously installed using [this tutorial](/book/installation-and-setup/git-setup_local.md)).
+
+3. Click on `File` in the top menu.
+4. Click on `Clone Repositery`. You should see the following window appear.
+
+```{figure} ../figures/CloneGitHubDesktop.png
+:name: CloneGitHubDesktop
+
+Cloning in GitHub Desktop.
+```
+5. Paste the link you've just copied and define the location on your device.

+````{tab-item} Cloning repository with Git in VS Code
+2. Open a new VS Code window. You should be greeted with a welcome page ({numref}`vscode-welcome`). On this page, click "Clone Git Repository". Alternatively, open the Source Control menu from the left side bar, and click on "Clone Repository".
+
+```{figure} ../images/vscode-welcome.png
+:name: vscode-welcome
+
+The VS Code welcome screen.
+```
+
+3. On the top of your screen, you should get a prompt asking you for a URL. In this field, paste the link you copied from GitLab and press enter. It will ask you to choose the location of the repository. After you've chosen a location, a final prompt will show up asking if you want to open the repository. Click on "Open".
+
+4. You now have a local copy of the repository.
