 Hints can be checked for basic correctness by running the parser:
 
-    ./compile-hints . /dev/null
+    ./run-test.sh
+
+Please add it via pre-commit hoot:
+
+    ln -s ../../etc/pre-commit .git/hooks/
+
+You can compile hints manually with:
+
+    compile-hints . /dev/null
 
 An empty output is a sign of goodness. If you want to see the resulting hint
 dictionaries, substitute `/dev/null` with a valid directory name.
