Notes
-----

-  | If you have already successfully hardened your blocks and have a clean
   |  ``user_project_wrapper``, you don't have to recreate it and can just reuse it.
   | This is only if no changes have been made to the user project area or to the tools that
   |  require you to reharden your design(s).

-  | If you will use openlane to harden your blocks, you can refer to
   |  this `README <https://github.com/efabless/caravel/blob/master/openlane/README.rst>`__.

-  | **IMPORTANT**. Do not forget to run ``make uncompress -j4`` in your user project root
   |  directory before you start working. Likewise, before you commit and push your
   |  changes back, run ``make compress -j4``.

-  | If you already have a clean working tree in a previously cloned repository from
   |  those listed above, what you need to do is:
   |  ``git pull   git checkout tag``
