Instead of pointing directly to objects, refs can also point to other refs! When that happens, they are called "symbolic refs". You can create or update a symbolic ref using git symbolic-ref Usually, you will only encounter a special symbolic ref called "HEAD". This ref is special in that it doesn't start with "refs/"! You might already have seen it in the other levels - it's the only thing that's always there! Try pointing HEAD to the refs in this repository!
