Git commit 3d976dd56236b2bb042e6a9f330b6a73226be5fe by Mauro Carvalho Chehab. Committed on 13/11/2017 at 15:42. Pushed by mauroc into branch 'master'.
doc: update documentation about device settings There are a few items missing to document on device settings. The more important one is how to setup the configuration for satellite systems. So, improve documentation for them.
