+### Usage
+
+libra rebase [OPTIONS] <UPSTREAM>
+
+### Arguments
+
+-   <UPSTREAM> - The new "base" commit or branch. The commits from the current branch will be reapplied on top of this <UPSTREAM> commit.
+
+### Description
+
+​	Rebasing is the process of moving a sequence of commits to a new base commit. This command rewrites the project history by creating fresh commits that apply the same set of changes but from a different starting point.
+
+### Example
+
+ \- libra rebase master
+ \- libra rebase <commit-hash>
+
+ <Note type="note" title="Note">
+   All parameters should align with Git’s behavior as closely as possible, but
+   there may be some differences. Refs https://git-scm.com/docs/git-branch for
+   more information.
