Sourcegraph.com searches over the top 100k GitHub repositories by default. You can search over other public
repositories by providing a repo: filter or you can search all of your own private code by setting up a self-hosted Sourcegraph instance.

If your open-source repository is not yet indexed, you can add it by going to <code>sourcegraph.com/github.com/$OWNER/$REPO</code>,
or search your private code by setting up a self-hosted Sourcegraph instance.
