From ef164196cbe6d703366b61070b6b6f1a6bc0038f Mon Sep 17 00:00:00 2001 From: Patrick Georgi Date: Wed, 3 Nov 2021 10:11:35 +0000 Subject: Documentation: Add some notes about how to integrate FSP While we don't _want_ FSP, we can't get around it sometimes. But when using it, we can still try to establish best practices to make life easier for everybody.
