-## Updating Hadrian
-
-
-Hadrian is a submodule of the main GHC git repository, located at the root of the source tree, at path `hadrian/`. This submodule tracks `https://git.haskell.org/hadrian.git`, but the repository where Hadrian development actually takes place is on github, at `https://github.com/snowleopard/hadrian.git`. The former is manually updated with new commits from the latter every now and then, which means you occasionally might need to point `hadrian/` to the github repository's `master` branch to get some fixes or new features. This can be done as follows:
-
-```
-# move to the root of your ghc source tree, then:
-$ cd hadrian
-$ git remote add snowleopard https://github.com/snowleopard/hadrian.git
-$ git fetch snowleopard && git checkout snowleopard/master
-```
