Some basic Git instructions for Github for Mac and the command line

Using Git version control for code projects

Creating a new code repo from a local working copy

with the Github for Mac app

1. From the repositories view in the app, drag the project folder to the bottom of the left sidebar.
2. Hit "Yes" when it asks if you want to create a local git repository
3. Go to "Changes" view (⌘2)
4. Select the files that you want to commit their current state to the repository. You can view the changes of the file by clicking on the double up arrow on the file name bar.
5. Type a commit summary, usually a description of what you've just added or changed.
6. Click 'Commit'. This commits the current state of the code to your local repository. Do this every time to do something significant like fix a bug or develop a feature. Commit early and often. Each state of code is available to you at any time via the History view (⌘1).

with the command line

• Open Terminal.app
• "cd" to directory

cd path/to/directory

• Initiate a git repository

git init .

• Add existing files

git add .

• Commit all files (-a) and add a message (-m)

git commit -a -m "commit message goes here"

Cloning (checking out) someone else's repository

with the Github for Mac app

• Visit the repo on Github.com and click the "clone to Mac" button, or...
• Select the repo in the Repositories list within the app, under the cremalab account.

with the command line

• "cd" to desired directory
• clone the repo with the clone url

git clone [email protected]:albatrocity/gratuitator.git

Syncing repository branches with a remote repository

with the Github for Mac app

1. Make sure you have committed the current state of your code
2. Drill into your repo in the app and click Sync Branch in the upper right corner. This pulls down the latest code from the remote repository, merges your code with it, and pushes your changes to the remote repository.

If you only want to get the latest code from the remote repo, select Repository > Pull (⇧⌘P) from the menu bar. This merges the remote code with your local code but does not push up your changes.

If you only want to push up your current state to the remote reop, select Repository > Push (⌘P). This will only work if you already have the most up to date code from the repo.

with the command line

• Make sure you have committed your current state.
• Get the most up to date code from the remote repo

git pull origin main

• Push your local code to the remote repo

git push origin main

Creating a new calculator project (locally):
If you’re working on a personal or relationship-based project and want to find exact age differences, start by using an online Age Difference Calculator like Aurexa Finance’s tool
. It works like managing a repo — you enter two birth dates (as your “data files”) and get an instant “result commit” showing the exact years, months, and days between them.

With online tools (like the calculator):

Go to the calculator page

Enter two dates (your birthdates or anyone’s)

Click "Calculate" to see the detailed difference instantly

Each calculation can be saved or noted for analysis — like committing a version in Git

If you want to track multiple relationships or records:
Think of each pair of dates as a “branch.” You can calculate, compare, and save them — similar to how GitHub manages versions. The calculator helps keep your data organized and precise.

Syncing your data or results:
If you’re working across devices or sharing with others, save the results or export them — that’s like a “push” to your online record. Anytime you check again, you can “pull” fresh results by recalculating with updated birthdates.

The Age Difference Calculator keeps your records accurate, just like Git keeps your code clean and versioned. Simple, smart, and fully automated — great for both personal and analytical use.
