 ## Quickstart
 
+The fastest (less than 20min) way to build z-wave-protocol-controller from scratch
+is to delegate all tasks to docker.
+
+This one-liner will do download latest release, setup environment, build, test, package...:
+
+```sh
+docker build https://github.com/SiliconLabsSoftware/z-wave-protocol-controller.git#ver_1.7.0
+```
+
+Alternatively, it can also build from sources, and checked using:
+
+```sh
+git clone https://github.com/SiliconLabsSoftware/z-wave-protocol-controller
+cd z-wave-protocol-controller
+docker build --tag z-wave-protocol-controller:main .
+docker run --tag z-wave-protocol-controller:main
+```
+
+Power users might prefer to directly work on a native GNU/Linux environment,
+and look at [./helper.mk](helper.mk) script that details all the needed steps
+to setup system and before using CMake.
+
+At the moment stable version of Debian is supported,
+so it should work also in relatives projects (Ubuntu, RaspiOS, WSL2 etc)
+and should be easy to adapt to other distributions.
+
+```sh
+./helper.mk help
+./helper.mk setup  # To setup developer system (once)
+./helper.mk VERBOSE=1 # Default build tasks verbosely (depends on setup)"
+./helper.mk run # Run entry-point application
+```
+
+It should print zpc's help.
+
+To use it, a Silicon Labs' Z-Wave NCP should be plugged in USB port
+to verify you can check firmware version:
+
+```sh
+serial=$(ls /dev/serial/by-id/usb-Silicon_Labs* | head -n1)
+./helper.mk run run_args="--zpc.serial=${serial} --zpc.ncp_version"
+# <i> [zpc_ncp_update] chip_serial_api_version: 7.23.1
+```
+
+Let's interact with the inbuilt shell of zpc:
+
+```sh
+./helper.mk run run_args="--zpc.serial=${serial}"
+ZPC>help
