Basic Git Branching Workflow

There are many potential Git workflows. The following is a basic workflow for someone working alone, using different local branches, pushing directly the master remote branch.

To make a new branch locally:

1. git checkout -b my_branch_name - create and move to a new branch
2. Do work.
3. git status - check on things.
4. git add . - stage changes to be committed.
5. git commit -m "my_commit-message" - commit changes.

How to fork, clone, and sync from a GitHub repository.

1. From the GitHub GUI: Fork the repository (click fork).
2. From your forked repository in the GitHub GUI: Click clone and copy the URL.
3. From the command line: in the directory you want to put your local copy of the repository, type git status to make sure you are not already in a local git repository folder.
4. Then type git clone insert_the_url_from_above
5. cd into the cloned repository.
6. git remote -v to see the tracking versions. You should see origin, but no upstream.
7. From the original repository in the GitHub GUI (not yours): Click clone and copy the URL.
8. git remote add upstream insert_url_of_original_repository_from_the_step_above - the URL to insert will NOT have your username in it.

1. See if you have Visual Studio Code installed by looking in your apps. If you don't, have it installed, install it from here
2. Configure Visual Studio Code to be your editor for git. From the command line run: git config --global core.editor "code -w"
3. Mac users: Set Visual Studio Code to open with code from the command line outside VS Code. Instructions here, press command + shift + p
4. Select Shell Command: Install 'code' command in PATH. Windows users should have the functionality automatically.
5. Install the Python extension for Visual Studio Code. Click on the Extensions icon in the left side bar and search for Python. Select and install it.
6. Make black your autoformatter. In the top menu bar go Code -> Preferences -> Settings and type black. Select Under Python > Formating: Provider select black. You may need to pip install black on the comma
