Install Git on MacOS

brew install git

Install Git on Windows

Set Config

git config --global user.name "[name]"
git config --global user.email "[email]"

example:

git config --global user.name "testuser"
git config --global user.email "email@emailtest.com"

Set Editor to nano on MacOS

git config --global core.editor "nano"

export GIT_EDITOR=nano

export VISUAL=nano
export EDITOR="$VISUAL"

Generate SSH Key

On Windows

ssh-keygen.exe -t rsa -b 4096

On MacOS / Linux

ssh-keygen -t rsa -b 4096

Press Enter - No Passphrase, leave empty

Take public key and add into Gitea

Key is located in /Users/<username>/.ssh

Take id_rsa.pub - Open in text editor. Copy contents.

Go to profile on Gitea HERE: https://gitea.fifthdread.com/user/settings/keys

Add Key

Paste public key information into Content Box.

It should auto-complete the Key Name. Click Add Key to complete.

Your machine can now trusted to access the Git Repository via SSH. You can now pull and push to the repo.

Cloning a project / Pulling a Project

To Clone a project from the repo, go to the project on gitea.

Switch to SSH and click the Copy button to copy the SSH access URL.

Navigate to the directory you want to clone your project into. In the example below, I go to a ProjectFiles folder.

Type git clone "URL" "DirectoryName"

git clone <PASTE URL HERE> <BRANCH NAME HERE>

The branch name is not required. It is simply the name of the directory you are going to use for the files. I like to stay organized and make it the name of the branch.

it will now download the repo.

Renaming your local git branch

This is important, as if you do not rename your branch prior to pushing it to the repo, it will override the main branch. Not good!

Check what branch you are on, and what the branch name is:

git branch

Rename Main branch to something else via the below command:

git branch -m <NAME>

Branches

To upload changes to a project, make sure you are working on a separate branch- RENAME YOUR BRANCH

Never upload directly to the main branch on a collaborative project, as branch merges need to be reviewed by the team prior to being merged.

Committing Changes

First verify you have renamed the Branch

git branch

If it is something other than main, we can proceed.

To see the changes you made since the repo was pulled, type:

git diff

Commit the changes with the following command:

git commit -a

The NANO editor will appear if on MacOS, or your preferred editor on Windows, such as Notepad++. Edit the top of the document with your commit comments. Save when complete.

If you opened in VIM and not nano, it looks like this... ew. Don't ask me how VIM works.
