+#### Mirroring Repos
+
+This mirrors a repo to your current repo
+<details>
+
+<summary>Explanation</summary>
+
+	`git remote add {name_of_remote} {remote_url}`
+    Adds a remote to your instance under {name_of_remote} (any unique name you decide) which will mirror {remote_url} to your repo.
+    
+
+-----
+	git push origin 'refs/remotes/{name_of_remote}/:refs/heads/' --prune --tags
+    Pushes your remote and prunes all current branchs that don't exist on the remote anymore.
+    
+>     Warning! This means that all local work on that mirror can be lost. Generally I would recommend you don't work directly on the mirror repo. So the repo will looking like: Original > Mirrored Repo > Your Fork.
