+# View The Current File In GitHub
+
+Sometimes when I'm browsing some code in Vim, I'll want to open up the a file
+in GitHub. This is usually so that I can grab a URL to share as a point of
+reference in a conversation.
+
+To do this, I run [`vim-fugitive`](https://github.com/tpope/vim-fugitive)'s
+`:Gbrowse` which will open up the current file for the current commit on the
+current branch.
+
+This works great if your current branch is the `main` branch. Or if your
+current branch has previously been pushed up as a remote. It doesn't work so
+well if you are on a local-only feature branch. You'll get the classic Star
+Wars themed GitHub 404 page.
+
+There is a handy workaround. You can specify the branch and file you want when
+you run the command.
+
+```
+:Gbrowse main:app/models/user.rb
+```
+
+That will open the specified file (`app/models/user.rb`) as it exists on the
+specified branch (`main`).
+
+A shorthand of that for the current file looks like this:
+
+```
+:Gbrowse main:%
+```
