         In Git < 2.23, ``git restore`` is not yet available. In this case you
         still have to use ``git checkout``:

 If you have accidentally committed to an existing branch instead of creating a
 new branch first, you can change this in the following three steps:
 
-:samp:`$ git branch [{NEW_BRANCH}]`
+:samp:`$ git branch {NEW_BRANCH}`
     create a new branch
 :samp:`$ git reset HEAD~ --hard`
      resets the last commit in your active branch
-:samp:`$ git switch [{NEW_BRANCH}]`
+:samp:`$ git switch {NEW_BRANCH}`
     applies the changes to the new branch
 
 The procedure is similar if you have accidentally made a commit in the wrong
 branch:
 
 :samp:`$ git reset HEAD~`
     resets the last commit, and its changes are now reapplied to the stage area.
-:samp:`$ git switch [{DESIRED_BRANCH}]`
+:samp:`$ git switch {DESIRED_BRANCH}`

-:samp:`$ git commit -m '[{COMMIT_MESSAGE}]'`
+:samp:`$ git commit -m '{COMMIT_MESSAGE}'`
