+#################################################
+# This script aids building mayhem inside docker
+#
+# Basic usage:
+# - Build dev container: ./dockerize.sh build
+# - Build mayhem: ./dockerize.sh
+#
+# The image will be automatically build if it
+# does not exist, but if the dockerfile changes
+# it need to be rebuilt manually.
+# 
+# Advanced parameters:
+# - Get a shell inside the build image to
+#   inspect problems: ./dockerize.sh shell
+# - Give additional parameters to the container:
+#   ./dockerize.sh -j10
+#   ./dockerize.sh ninja -j10
+# - Use a different dockerfile:
+#   ./dockerize.sh build dockerfile-other
+# - Use a different cpu architecture:
+#   ./dockerize.sh build dockerfile-nogit-arm arm64
+#
+# Environment variables:
+# - It is possible to override the default image
+#   name that is being used to build and run the
+#   build container using an environment variable.
+#   The default is 'portapack-dev'
+#   Override by setting the following environment
+#   variable: MAYHEM_DEV_DOCKER_IMAGE

+Portapack H4 is an add-on for the HackRF Software Defined Radio (SDR) platform.
+
+The improvements of H4:
+1.GPIO port! The H4M adds a GPIO port so users can make their own add-ons for the H4M, just like the flipper.
+2.Advanced battery management IC (battery %, voltage, current/draw, etc...)
+3.Single power on/off switch.
+4.When powered off, the battery will no longer phantom drain.
+5.flat design, going back to the iPod style click wheel. (so no more broken buttons and encoders!)
+6.Improved charge speeds.
+7.Built in mic (and mic switch between internal and external).
+8.Matte screen.
