+# Setting up a Local Development Environment
+In order to work on the HPR codebase, first of all create your
+account, as explained in [developer information](developer_information.md).
+
+## Create your local environment
+The next step is to create your development environment locally:
+1. Fork the HPR repository you want to work on. Do this by clicking
+   the Fork button top right in the repository header:
+   
+   ![repository header](assets/images/repository-header.png)
+   
+2. Go to your terminal on your computer, and clone the HPR repository
+   locally:
+   ```` 
+   $ git clone gitea@repo.anhonesthost.net:HPR/hpr_documentation.git
+   ````
+   It doesn't matter if you use the ssh or http link for the code -
+   you don't have write access to the main repository, so you won't be
+   pushing code back there.
+3. Change to the clone repository - you will now see the remote listed
+   as origin:
+   ````
+   $ cd hpr_documentation
+   $ git remote -v
+   origin	gitea@repo.anhonesthost.net:HPR/hpr_documentation.git (fetch)
+   origin	gitea@repo.anhonesthost.net:HPR/hpr_documentation.git (push)
+   ````
+4. Create a remote for your fork of the repository:
+   ````
+   $ git remote add upstream gitea@repo.anhonesthost.net:[YOUR_USER]/hpr_documentation.git
+   $ git remote -v
+   origin	gitea@repo.anhonesthost.net:HPR/hpr_documentation.git (fetch)
+   origin	gitea@repo.anhonesthost.net:HPR/hpr_documentation.git (push)
+   upstream	gitea@repo.anhonesthost.net:[YOUR_USER]/hpr_documentation.git (fetch)
+   upstream	gitea@repo.anhonesthost.net:[YOUR_USER]/hpr_documentation.git (push)
+   ````
+
+You now have a repository you can keep up to date with the main repo,
+and also work on making additions.
+
+## Making code changes
+1. In order to make changes, the first step is to update your local
+   repository:
+   ````
+   $ git checkout main    # In case you are still in a branch from an earlier change
+   $ git pull origin
+   ````
+2. Create a branch to work on the changes:
+   ````
+   $ git checkout -b adding-developer-setup-information
+   ````
+3. Make the changes
+4. Check the changes work! You don't want to push broken code upstream!
+5. Commit your changes locally
+   ````
+   $ git add *
+   $ git commit 
+   ````
+   Note - the commit message should have the issue number at the
+   beginning. So in this case, "I6 - Document how to create local
+   environment"
+6. Push the changes to **your** repository:
+   ````
+   $ git push upstream
+   ````
+7. Go to your repository online - you will now see an option to create
+   a pull request against the main HPR repository. Click the Create
+   **Pull Request** button and fill out the form.
+
+8. Once the pull request is accepted, you can delete your local branch
+   if you wish.
+
+## Summary
+Using this approach means contributing is straight forward, and
+doesn't require everyone to have write access to the main HPR
+repositories.  Since you are pulling from the origin repositories, you
+will always be working on up to date code.
