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"

 # IfPlease thisfollow flag (DISTRO_FEATURES_append = " alexa_ffv"), we have to configure the kernel as mentioned here, so as to simulate FFV using USB Micorphonethe steps mentioned here 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
