 # Installation
 
+## Prerequisites
+
+You need to have go and dep utils installed on your machine.
+Ensure that GOPATH environment variable is set to desired location.
+Code generation for CRD controller uses kubernetes/hack as a dependency, so before use code generation, execute:
+
+`go get k8s.io/kubernetes/hack`
+
+## You can `go get`
+
+Due to the repository privacy, you should to add SSH key to your github user to clone repository using `go get` command.
+Using `go get` you receive correct repository location ad $GOHOME/go/src which is needed to restore dependencies.
+Configure SSH key due to this article: https://help.github.com/articles/adding-a-new-ssh-key-to-your-github-account/
+
+After SSH key configured, you must tell git to use SSH. To do it use next command:
+
+`git config --global url.git@github.com:.insteadOf https://github.com/`
+
+After this is done, use next command to clone the repo:
+
+`go get github.com/nirmata/kube-policy`
+
+## Or `git clone`
+
+If you don't want to use SSH, you just can clone repo with git, but ensure that repo will be inside this path: $GOPATH/src/.
+
+`git clone https://github.com/nirmata/kube-policy.git $GOPATH/src/nirmata/kube-policy`
+
+## Restore dependencies
+
+Navigate to kube-policy project dir and execute:
+`dep restore`
+This will install necessary dependencies described in README.md
