-### Download & Install
+### Build:
+Clone the repository:
+```
+git clone --depth 1 https://github.com/openark/zookeepercli.git && zookeepercli
+```
 
-There are [pre built binaries](https://github.com/outbrain/zookeepercli/releases) for download.
-You can find `RPM` and `deb` packages, as well as pre-compiled, dependency free `zookeepercli` executable binary.
-In fact, the only file installed by the pre-built `RPM` and `deb` packages is said executable binary file. 
+Build :
+```
+make build                   # build binary with local goland
+make package                 # previous + build deb, rpm, apk, tar, zip packages
+make all                     # all previous steps
 
-Otherwise the source code is freely available; you will need `git` installed as well as `go`, and you're on your own.
+make build_in_docker         # build binary with using docker container (golang-alpine)
+make package_in_docker       # previous + build deb, rpm, apk, tar, zip packages with using docker container
+make build_docker_image      # build docker image with zookeepercli
+make all_in_docker           # all previous steps
 
-  
-### Usage:
+make clean                   # clean all build artifacts
+```
+
+For build packages locally you need requires fpm: https://github.com/jordansissel/fpm.
+
+You can find the binary in the `bin` directory. \
+Also you can find `deb`, `rpm`, `apk`, `tar` and `zip` packages in pkgs_out.
