-> `<3` indicates that the local branch is 3 commits behind the upstream/remote branch, and could be updated.
-
-> `*2` indicates that the branch is now dirty, with 2 files modified but not committed.
-
-> `>1` indicates that the local branch has 1 commit which has not yet been pushed.
-
-> `+1` would indicate that you have staged 1 file before comitting, but that is not shown above.
-
-> `?4` would indicate that there are 4 untracked files in the tree, also not shown.
-
-> `#` indicates that `git status` was taking too long, so dirty `*` staged `+` and untracked `?` markers will not be shown this time.  `git status` will continue running in the background, so after a few moments, hitting `<Enter>` again should give you an up-to-date summary.

 We also have some indicators for the current branch:
 
 > `[branch_name]` means you are on a branch with an upstream
-
+>
 > `(branch_name)` means you are on a branch without an upstream
-
+>
 > `{branch_name\mode}` means you are in the middle of a merge, rebase, cherry-pick, revert or bisect
-
-> `<commit_id>` means you are detached on the given commit
+>
+> `<commit_id>` means you are detached on the given commit, tag, or remote branch
 
 The symbols (or "markers") can be changed by editing the `prompt.sh` file directly (and reloading it of course).  The numbers or the markers can be omitted by removing the `_count` or `_mark` variables from the `PS1` prompt below.
