+# Packaging Mu using WiX
+
+This is an experiment. So far, it's nearly but not quite working.
+
+To build the MSI package:
+
+1. Run `pynsist installer.cfg --no-makensis` to assemble the necessary files.
+2. Run `prep_files.py` in this folder to move some files and call 'heat' to
+   make a list of the files.
+3. Run `wixit.py` in this folder to build the msi package.
