+ref-transaction
+~~~~~~~~~~~~~~~
+
+This hook is invoked by any Git command that performs reference
+updates. It executes whenever a reference transaction is prepared,
+committed or aborted and may thus get called multiple times.
+
+The hook takes exactly one argument, which is the current state the
+given reference transaction is in:
+
+    - "prepared": All reference updates have been queued to the
+      transaction and references were locked on disk.
+
+    - "committed": The reference transaction was committed and all
+      references now have their respective new value.
+
+    - "aborted": The reference transaction was aborted, no changes
+      were performed and the locks have been released.
+
+For each reference update that was added to the transaction, the hook
+receives on standard input a line of the format:
+
+  <old-value> SP <new-value> SP <ref-name> LF
+
+The exit status of the hook is ignored for any state except for the
+"prepared" state. In the "prepared" state, a non-zero exit status will
+cause the transaction to be aborted. The hook will not be called with
+"aborted" state in that case.

+p4-changelist
+~~~~~~~~~~~~~
+
+This hook is invoked by `git-p4 submit`.
+
+The `p4-changelist` hook is executed after the changelist
+message has been edited by the user. It can be bypassed with the
+`--no-verify` option. It takes a single parameter, the name
+of the file that holds the proposed changelist text. Exiting
+with a non-zero status causes the command to abort.
+
+The hook is allowed to edit the changelist file and can be used
+to normalize the text into some project standard format. It can
+also be used to refuse the Submit after inspect the message file.
+
+Run `git-p4 submit --help` for details.
+
+p4-prepare-changelist
+~~~~~~~~~~~~~~~~~~~~~
+
+This hook is invoked by `git-p4 submit`.
+
+The `p4-prepare-changelist` hook is executed right after preparing
+the default changelist message and before the editor is started.
+It takes one parameter, the name of the file that contains the
+changelist text. Exiting with a non-zero status from the script
+will abort the process.
+
+The purpose of the hook is to edit the message file in place,
+and it is not supressed by the `--no-verify` option. This hook
+is called even if `--prepare-p4-only` is set.
+
+Run `git-p4 submit --help` for details.
+
+p4-post-changelist
+~~~~~~~~~~~~~~~~~~
+
+This hook is invoked by `git-p4 submit`.
+
+The `p4-post-changelist` hook is invoked after the submit has
+successfully occured in P4. It takes no parameters and is meant
+primarily for notification and cannot affect the outcome of the
+git p4 submit action.
+
+Run `git-p4 submit --help` for details.
