+# Removing a git commit and force pushing to remove it from history
+
+I accidentally triggered a commit which added a big chunk of unwanted data to my repository. I didn't want this to stick around in the history forever, and no-one else was pulling from the repo, so I decided to use force push to remove the rogue commit entirely.
+
+I figured out the commit hash of the previous version that I wanted to restore and ran:
+
+    git reset --hard 1909f93
+
+Then I ran the force push like this:
+
+    git push --force origin main
