+# NAME
+
+av-stack-branch - Create or rename a branch in the stack
+
+# SYNOPSIS
+
+`av stack branch [-m | --rename] [--parent <parent_branch>] <branch-name>`
+
+# DESCRIPTION
+
+Create a new branch that is stacked on the current branch by default
+
+If the --rename/-m flag is given, the current branch is renamed to the name
+instead of creating a new branch. Branches should only be renamed
+with this command (not with git branch -m ...) because av needs to update
+internal tracking metadata that defines the order of branches within a stack.
+
+# OPTIONS
+
+`--parent <parent_branch>`
+: Instead of creating a new branch from current branch, create it from
+  specified `<parent_branch>`
+
+`-m, --rename`
+: Rename the current branch to the provided `<branch_name>` instead of
+  creating a new one.
