-Dockerfile to create a [Faasd](https://github.com/openfaas/faasd/) image.
+# WHAT?
 
-While Faasd can't run in a container, this image **can** be imported into
+Automate creating a [Faasd](https://github.com/openfaas/faasd/) image.
+
+Goal is to run this image via
 [ignite](https://github.com/weaveworks/ignite) which runs it in a 
 [firecracker](https://firecracker-microvm.github.io) microvm.
 
+# WHY?
+
 I need to do this because I need to run Faasd in the same machine as
 dockerized services and according to its documentation that shouldn't
 be done because both use incompatible versions of underlying dependencies.

 Also in this way resource usage of Faasd and all "lambdas" in it is capped
 by the VM resources, and the rest of the system is sort-of-protected
 by the VM sandbox.
+
+# HOW?
+
+Assuming you have ignite and faas-cli installed:
+* replace `id_rsa.pub` with yours
+* run setup.sh 
+
+You will end up with:
+
+* A running ubuntu-based VM with faasd installed and running
+* Ssh enabled and accessible via that key
+* The faasd port exposed as localhost:8082
+* Your account logged into faasd
+* The figlet function installed and working
