+# Install Docker
+We need Docker with multi-platform image support. Plugin `buildx` is included by default to `docker-desktop`, and available for `docker-ce` and `moby-engine`.
+
+Debian: 
+```
+apt install moby-engine moby-buildx moby-compose moby-cli
+```
+Ubuntu:
+https://docs.docker.com/engine/install/ubuntu/
+
+# Prepare Docker to work with multi-platform images
+First time:
+```
+docker buildx create --name mybuilder
+docker buildx use mybuilder 
+```
+Each time:
+```
+docker run --privileged --rm tonistiigi/binfmt --install all 
+``` 
+
+# Update images for build
+```
+docker buildx bake debian 
+docker buildx bake fedora
+```
+
+# Run build and test on the all available platforms
+```
+docker buildx bake --progress="plain" bee2d 
+docker buildx bake --progress="plain" bee2f
+```
+
+# Run build and test on a one of available platforms
+```
+docker buildx build --platform linux/amd64 --progress="plain" -f dockerfiles/bee2d.Dockerfile .
+docker buildx build --platform linux/amd64 --progress="plain" -f dockerfiles/bee2f.Dockerfile .
+```
+
+# Run terminal on specified platform image
+```
+docker run --rm -it -v .:/usr/src --platform linux/s390x btls/fedora:cdev bash
+```
+
+### Turn on experimental features
+If option `platform` is unavailable in Docker, you need turn on experimental Docker CLI features in one of two ways. Either by setting an environment variable
+```
+$ export DOCKER_CLI_EXPERIMENTAL=enabled
+```
+or by turning the feature on in the config file $HOME/.docker/config.json:
+```
+{
+  …
+  "experimental" : "enabled"
+}
+```
