+
+## Makefile/Docker testing
+To test the build on various distro, we are using docker containers and a Makefile for orchestration.
+
+pros:
+* You are independent of third party CI runner config
+  (e.g. [github action virtual-environnments](https://github.com/actions/virtual-environments)).
+* You can run it locally on your linux system.
+* Most CI provide runners with docker and Makefile installed.
+
+cons:
+* Only GNU/Linux distro supported.
+
+### Usage
+To get the help simply type:
+```sh
+make
+```
+
+note: you can also use from top directory
+```sh
+make --directory=ci
+```
+
+### Example
+For example to test mips32 inside an container:
+```sh
+make mips32_test
+```
+
+### Docker layers
+Dockerfile is splitted in several stages.
+
+![docker](doc/docker.svg)
+
+
+## Makefile/Vagrant testing
+To test build for FreeBSD we are using Vagrant and VirtualBox box.
+
+This is similar to the docker stuff but use `vagrant` as `docker` cli and
+VirtuaBox to replace the docker engine daemon.
