+# filecoin-ffi build workaround
+
+As of this writing, .circleci doens't support arm based images and as a workaround we need to try and build the filecoin-ffi in a containerized environment.This means that we need to create a docker image using an ARM64 based operating system and build the binaries there.
+
+## Pre-requisites
+- docker
+- bash
+- tar
+
+There are 2 files in this repo:
+- Dockerfile this is the main docker file that will run the steps to build the latest master branch of filecoin-ffi on ubuntu
+- run_arm_build_docker.sh - this script runs the docker build and extract the content from the image to the host.
+
+## Running
+```
+./run_arm_build_docker.sh
+```
+
+
+## Trial and error
+We can use some of these images as builders. They are all arm64 based.
+```
