+# Q&A
+
+## Q1
+
+What is the default branch name?
+
+## A1
+
+The default branch name is `master`. You can change it to any name you like. For
+example, you can change it to `main` by following the steps below:
+
+```
+git branch -m master main
+git fetch origin
+git branch -u origin/main main
+git remote set-head origin -a
+```
+
+## Q2
+
+What is the defference between `git branch` and `git branch -a`?
+
+## A2
+
+`git branch` shows only local branches, while `git branch -a` shows both local
+and remote branches.
+
+## Q3
+
+Fast-forward merge is not possible. How can I merge the feature branch into the
+main branch?
+
+## A3
+
+You can use `--no-ff` option to force a merge commit even if the merge is a
+fast-forward.
