To merge two branches in Git, you typically follow these steps:

   1. Switch to the branch where you want to merge changes (e.g., `git checkout branch-to-merge-into`).

   2. Run the command `git merge branch-to-merge-from`. This merges the changes from the specified branch into the current branch.

   3. Resolve any merge conflicts, if they occur.

   4. Commit the merge changes using `git commit`.
