+=== Notes on using Mender on Buildroot
+======================================
+Default configurations files
+----------------------------
+
+Buildroot comes with a default artifact_info and device_type configuration files
+in /etc/mender. They contain default values, and thus they should be overridden
+on a production system.
+
+The simplest way to do it is to change these files in an overlay or in a post
+build script.
+
+Configuring mender with certificates
+------------------------------------
+
+Mender uses TLS to communicate with the management server, and if you use a
+CA-signed certificate on the server, you should select the ca-certificates
+package otherwise it doesn't work.
