Sure, here are the steps on how to set up an editor to work with Git on Windows:

1. Open a Git Bash terminal.
2. Navigate to the local directory where you want to set up the editor.
3. Run the following command:

```
git config core.editor <editor-name>
```

Replace `<editor-name>` with the name of the editor you want to use. For example, to use Notepad++, you would run the following command:

```
git config core.editor notepad++
```

4. Verify that the editor has been set up correctly by running the following command:

```
git config core.editor
```

The output of this command should show the name of the editor you just set up.

Here are some of the most popular editors that you can use with Git on Windows:

* Notepad++
* Sublime Text
* Atom
* Visual Studio Code
* Vim
* Emacs

Once you have set up an editor, you can use it to edit your Git files. When you commit changes to your files, Git will open the editor so that you can review and save your changes.

Here are some additional tips for setting up an editor to work with Git on Windows:

* If you are using a text editor that is not installed by default, you will need to specify the full path to the editor executable when you run the `git config core.editor` command.
* You can also set up a different editor for different file types. For example, you could set up Notepad++ as your default editor for text files and Sublime Text as your default editor for code files.
* You can also set up the editor to wait for you to finish editing before it closes. This is useful if you want to make multiple changes to a file before you commit them.
