1. Initialize and download the code base
 - Example for RaspberryPi:
 $ repo init -u https://code.rdkcentral.com/r/manifests -m rdkv-nosrc.xml -b thunder-next
 $ repo sync

2. Download the meta-rdk-voice layer in project root
 $ git clone https://code.rdkcentral.com/r/components/generic/rdk-oe/meta-rdk-voice

3. Add to BBLAYERS
 $ vi meta-rdk/conf/bblayers.conf.sample
 BBLAYERS += "${@'${RDKROOT}/meta-rdk-voice' if os.path.isfile('${RDKROOT}/meta-rdk-voice/conf/layer.conf') else ''}"

4. Optionally if wanted to use MIC based implementation (Ignore if using BLE voice remote)
 $ vi meta-rdk-voice/conf/layer.conf
 - enable the below commented line
 #DISTRO_FEATURES_append = " alexa_ffv"

 # Please follow the steps mentioned in section #3.2 to enable USB audio kernel parameters (Not required for RaspberryPI).

5. Optionally For the external source builds (such as some Broadcom platforms) add below line in manifest/auto.conf
 - In <Manifest>.xml
   <project name="components/generic/avs/alexa_skill_mapper" revision="rdk-next"/>
 - In auto.conf (where brcmexternalsrc is enabled)
   BRCMEXTERNALSRC_pn-wpe-alexa += "components/generic/avs/alexa_skill_mapper:git/VoiceToApps"
   SRCPV_pn-wpe-alexa = "${BRCMEXTERNAL-SRCPV-CMF}"
 $ repo sync
6 .Build the image target
 - Example for RaspberryPi
 $ source meta-cmf-raspberrypi/setup-environment
 ### select meta-cmf-raspberrypi/conf/machine/raspberrypi-rdk-hybrid-thunder.conf ###
 $ bitbake rdk-generic-hybrid-thunder-image

Note: This configuration is not required for RaspberryPi platforms
# If FFV profile is enabled (DISTRO_FEATURES_append = " alexa_ffv") & we want to simulate audio input using a USB mic the below kernel configuration need to be enabled for non RPI platforms:

CONFIG_SND_HWDEP=m
CONFIG_SND_RAWMIDI=m
CONFIG_SND_USB_AUDIO=m

# After enabling the above kernel configs, recompile the kernel so that the support for USB audio will be enabled
