+Generate Dockerfile from jinja template
+-------------------
+
+Dockerfile and configuration can be generated by template. 
+
+- arch: one of `amd64` or `armhf`
+- flavor: refer to file in flavor/`flavor`.yml
+- image: base image
+- localbuild: build from local that will use mirror site if set
+- desktop: desktop environment which is set in flavor
+- addon_package: Debian package to be installed which is set in flavor
+
+Dockerfile and configuration are re-generate if they do not exist. Or you may force to re-generate by removing them with the command `make clean`.
