+## Setting up configuration files
+After setting up the basic environment, as described in the tutorial,
+init the build environment with this command:
 
-After the build directory has been generated, as outlined in the
-meta-exosense instructions, edit the following entries in
-conf/local.conf
+    `. oe-init-build-env ../build`
 
-    MACHINE ?= "qemux86"
-    PACKAGE_CLASSES ?= "package_rpm"
-    EXTRA_IMAGE_FEATURES = "debug-tweaks exosense"
-    IMAGE_INSTALL_append = " erlang-jlrdemo"
+Copy `meta-jlrdemo/build_conf/*.conf` into the `conf` subdirectory of
+the build directory you are currently in.
 
+	cp ../meta-jlrdemo/build_conf/*.conf conf
 
-The meta-jlrdemo/build_conf directory contains valid config files that can be installed in the created build/conf directory. Make sure to edit the directories
-in bblayers.conf to reflect the local structure before building.
+## Build the RPM 
+Since the demo is installed on Tizen, we will not create a complete

-In the build directory, do:
+Build the RPMs with:
 
-    bitbake erlang-jlrdemo
 
+    bitbake erlang-jlrdemo
 
 The rpms will be deposited in
