 ## About
 
 This repository creates packages (apk, deb, rpm, static) for various projects
-that can be found in [pkg](pkg) folder.
+and are published as a Docker image on Docker Hub.
 
 ## Usage
 
-_TODO_
+`vars.mk` contains variables that will be used by the main `Makefile` and
+also across projects in [pkg](pkg) folder. It contains the list of apk,
+deb and rpm releases to produce and repos with current versions of projects.
+
+`Makefile` contains targets to build specific or all packages and will output
+to `./bin` folder:
+
+```console
+# build debian packages for buildx project
+$ make deb-buildx
+# build deb and rpm packages for all projects
+$ make deb rpm
+```
+
+Each [project](pkg) has also its own `Makefile`, `Dockerfile` and bake
+definition to build and push packages:
+
+```console
+# build all packages for buildx v0.9.1
+$ cd pkg/buildx/ 
+$ BUILD_VERSION=v0.9.1 make pkg
+# Push image to dockereng/packaging:buildx-v0.9.1
+$ docker buildx bake --push --set *.tags=dockereng/packaging:buildx-v0.9.1 release
+```
+
+Packages are published to Docker Hub as a Docker image. You can use a tool like [Undock](https://github.com/crazy-max/undock)
+to extract packages:
+
+```shell
+$ undock --wrap --rm-dist --all dockereng/packaging:buildx-v0.9.1 ./bin/undock
+```
