+Please read the TODO file in this directory for ideas on what to work on.
+Before submitting patches, run the test suite to ensure nothing has regressed:
+
+    # From within your LLVM source directory.
+    utils/lit/lit.py \
+        --path /path/to/your/llvm/build/bin \
+        utils/lit/tests
+
+Note that lit's tests depend on 'not' and 'FileCheck', LLVM utilities.
+You will need to have built LLVM tools in order to run lit's test suite
+successfully.
