 Chromium OS that already has the changes you want merged to the branch in it
 i.e. if you want to push changes to crosutils.git, you must have src/scripts
 checked out. If this isn't true e.g. you are running this script from a
-minilayout or trying to upload an internal change from a non internal checkout,
+minilayout or trying to upload an internal change from a non-internal checkout,
 you must specify some extra options: use the --nomirror option and use -e to
-specify your email address. This tool will then checkout the git repo fresh
+specify your email address. This tool will then check out the git repo fresh
 using the credentials for the -e/email you specified and upload the change. Note
 you can always use this method but it's slower than the "mirrored" method and
 requires more typing :(.
 
 Examples:
-  cros_merge_to_branch 32027 32030 32031 release-R22.2723.B
+    cros_merge_to_branch 32027 32030 32031 release-R22.2723.B
 
 This will create changes for 32027, 32030 and 32031 on the R22 branch. To look
 up the name of a branch, go into a git sub-dir and type 'git branch -a' and the
 find the branch you want to merge to. If you want to upload internal changes
 from gerrit-int, you must prefix the gerrit change number with a * e.g.
 
-  cros_merge_to_branch *26108 release-R22.2723.B
+    cros_merge_to_branch *26108 release-R22.2723.B
