+# Amend Commits With Fugitive
+
+Let's assume you are using [fugitive](https://github.com/tpope/vim-fugitive)
+for Git integration with Vim. You've made a commit that you want to amend.
+First, stage any changes that should be included in the amend with `:Gstatus` or
+`:Ge:`. Then hit `ca` to open up the commit window for amending. Save and
+quit when you are finished.
+
+Want to view the aggregate changes? Open the commit window for amending in
+verbose mode with `cva`.
+
+See the [vim-fugitive
+docs](https://github.com/tpope/vim-fugitive/blob/master/doc/fugitive.txt)
+for more details.
