+#### Mark Broken Packages
+
+Packages that do not get fixed can be marked broken with the following
+commands.  First check which packages are broken:
+
+```console
+$ maintainers/scripts/haskell/hydra-report.hs get-report
+$ maintainers/scripts/haskell/hydra-report.hs mark-broken-list
+```
+
+This shows a list of packages that are thought to be broken.
+
+Next, run the following command.
+
+```console
+$ maintainers/scripts/haskell/mark-broken.sh --do-commit
+```
+
+This first opens up an editor with the broken package list.  Some of these
+packages may have a maintainer in Nixpkgs.  If these maintainers have not been
+given 7 days to fix up their package, then make sure to remove those packages
+from the list.  After saving and exiting the editor, the following will
+happen:
+
+- packages from the list will be added to
+  [`configuration-hackage2nix/broken.yaml`](configuration-hackage2nix/broken.yaml)
+- `hackage-packages.nix` will be regenerated
+- the
+  [`configuration-hackage2nix/transitive-broken.yaml`](configuration-hackage2nix/transitive-broken.yaml)
+  file will be regenerated
+- `hackage-packages.nix` will be regenerated again
