+# Set Default Branch Name For New Repos
+
+When you run `git init` in a directory, it will initialize that directory as a
+`git` repository. The default branch name for any new git repository is
+`master`. A better name for the base branch would be something like `main`.
+
+To set `main` as the new default for all new repos, you can run the following
+`git` command.
+
+```bash
+$ git config --global init.defaultBranch main
+```
+
+This will update your `.gitconfig` file to contain the following lines.
+
+```
+[init]
+	defaultBranch = main
+```
+
+Try running `git init` in a fresh directory and then `git branch
+--show-current` to see that the base branch is now defaulting to `main`.
