-HOW TO BUILD LINPHONE / FLEXISIP USING YOCTO / BITBAKE
+Yocto BSP layer for Linphone
+=============================
+
+This layer provides support for linphone for use with :
+master : 		Stable linphone version for Yocto Fido.
+yocto-jethro : 	Stable linphone version for Yocto Jehtro.
+dev-fido :		Follows linphone development for Yocto Fido.
+
+This layer depends on the following layers:
+
+	poky/meta 
+	poky/meta-yocto 
+	meta-openembedded/meta-oe 
+	meta-openembedded/meta-multimedia 
+	meta-openembedded/meta-networking 
+	meta-openembedded/meta-python

+How to build linphone / flexisip with Yocto
+--------------------------------------------
 
 - Edit the conf/bblayers.conf file in your build directory and append to the BBLAYERS list the path to the meta-bc directory
+as well as its dependencies listed above
 - Edit the conf/local.conf file in your build directory and add the following line:
-IMAGE_INSTALL_append = "linphone flexisip"
+IMAGE_INSTALL_append = "linphone flexisip" to add the package to your image.
 - Now build your image normally (bitbake core-image-minimal or other)
 - You can also skip the two previous steps and only compile linphone or flexisip directly with bitbake (bitbake linphone; bitbake flexisip)
 
-HOW TO DOWNLOAD AND INSTALL LINPHONE / FLEXISIP USING BELLEDONNE COMMUNICATIONS IPK REPOSITORY
+How to download and install linphone / flexisip using belledonne communication's ipk repository
+------------------------------------------------------------------------------------------------
+If you don't want to compile and download the package by yourself, you can use the ones that are already compiled
+on Belledonne communication repository.
+The packages are built for an arm target (Wandboard solo).
 
 - First make sure your image is built with opkg. To do so, add the following into the local.conf file in your fsl-<version>/ build/conf directory (and also add some free space for download/install ipk purposes):
 IMAGE_INSTALL_append = " opkg"
 IMAGE_ROOTFS_EXTRA_SPACE="204800"
-- Create the file in /etc/opkg/bc.conf in your hardware
+- Create the file in /etc/opkg/bc.conf on your target
 - Add the following into the file:
 src/gz all http://linphone.org/snapshots/ipk/all
 src/gz cortexa9hf-vfp-neon http://linphone.org/snapshots/ipk/cortexa9hf-vfp-neon
 src/gz cortexa9hf-vfp-neon-mx6qdl http://linphone.org/snapshots/ipk/cortexa9hf-vfp-neon-mx6qdl
 src/gz wandboard_solo http://linphone.org/snapshots/ipk/wandboard_solo
-- Run the following commands:
+- Run the following commands on the target:
 $ opkg update
 $ opkg install linphone
 $ opkg install flexisip
