-#Description
+# Description
The **_PatchFv.py_** tool allows the developer to fix up FD images to follow the
Intel FSP Architecture specification. It also makes the FD image relocatable.
The tool is written in Python and uses Python 2.7 or later to run.
Consider using the tool in a build script.

This is the first argument that **_PatchFv.py_** requires. It is the build
directory for all firmware volumes created during the FSP build. The path must
be either an absolute path or a relevant path, relevant to the top level of the
FSP tree.
