Here's an overview of how to use Sublime Merge with your code repositories:

1. Download and install the latest version of Sublime Text from 'Sublime Text website'(https://www.sublimetext.com/).

2. Once installed, you can download the Git plugin for free by following these steps:

- Open up a web browser like Google Chrome or Mozilla Firefox.

- Type in 'Git plugin for Sublime Text' into your search bar and press enter.

3. When prompted with several results about downloading the Git plugin, click on any link that leads you to 'GitHub'(https://github.com) where developers share their work publicly so everyone can access it without paying anything at all!

4. After successfully installing git using pip (Python Package Installer), restart your editor before proceeding further since some plugins require a reload after installation:

```bash

# If you're on Mac or Linux:

$ cd ~/.local/share/composer/cache/repo/https/gitar.git/

# Or, if you're on Windows:

%UserProfile%\.atom\packages\git-rebase\.gitignore

# Then restart Sublime Text by closing and re-opening it.

```

5. Once everything has loaded properly after restarting your editor go to 'File' > 'Open Folder...' (or press ⌘ + Shift + P on Mac or Ctrl+Shift+B on Windows) then navigate through local disk C: drive until you reach where ever downloaded the sublime merge folder was extracted onto desktop etcetera depending upon operating system being used:

```

# On macOS:

~/Library/Application Support/Sublime Text 3/Packages/User

# Or, if using a newer version of Sublime on Windows or Linux

~\.config\SubL\Packages\User

```

6. Now that you've successfully installed the Git plugin in Sublime Merge:

- Open up any text file within sublime merge by double clicking its icon inside an open folder panel.

* This will bring up a new window showing all changes made since last commit along with buttons at top left corner allowing users to stage, unstage or stash individual lines of code as needed before committing entire files when ready.

7. The next step is setting up your Git repository so let's do that now:

```bash

# Create an empty directory for our git repo (we'll call it 'myrepo'):

$ mkdir myrepo

cd into the new folder:

cd myrepo

# Initialize a brand-new, bare-bones Git repository inside here using `git add .` followed by `git commit -m 'initial commit'`.

git init --bare

```

8. Finally, link this newly created bare repository with your local working copy like so:

```bash

# Clone the remote origin branch into a new directory called '.git' within our current working directory:

$ cd ~/

mkdir myrepo.git

git clone /path/to/remote/repo ./.git

# Add all files in `.git` to your local .gitignore file so they don't clutter up future commits

touch .gitignore

cat > .gitignore <

*.log

*.swp

*.cache*

!.git/

EOF

Now you're ready to start using Sublime Merge with Git!
