+## IOTA
+
+This code has now moved into a separate repository.
+If you set up your build environment after April 2020 it should already include
+the necessary changes.
+
+
+### Updating developer installations
+
+You can pick up iota from its new location by running the command
+```bash
+libtbx.install iota
+```
+which will install iota in the modules/ directory. You should also run
+```bash
+cd $(libtbx.find_in_repositories cctbx_project)
+git clean -diX iota
+```
+to remove any `.pyc` and other python runtime debris from the previous iota
+path, as these files could interfere with python package discovery.
+The clean command will ask for confirmation (enter `1`) before deleting files.
