+# Multi-Cluster-App-Deployer Controller Build Instructions
+
+This document will show how to build the `Multi-Cluster-App-Deployer` Kubernetes Controller that operates on on an AppWrapper kubernetes custom resource definition. It is for [master](https://github.com/IBM/multi-cluster-app-dispatcher/tree/master) branch.
+
+## 1. Pre-condition
+
+### Docker Environment
+
+To build `Multi-Cluster-App-Deployer`, a running Docker env. must be available. Here is a document on [Getting Started with Docker](https://www.docker.com/get-started). 
+
+### Clone Multi-Cluster-App-Deployer Git Repo
+
+Clone this repo in your local environement:
+
+```
+$ git clone git@github.com:IBM/multi-cluster-app-dispatcher.git
+Cloning into 'multi-cluster-app-dispatcher'...
+Checking connectivity... done.
+Checking out files: 100% (####/####), done.
+$
+```
+
+## 2. Building the Multi-Cluster-App-Deployer Controller 
+
+### Build the Executables 
+
+Run the build script `build.sh`:
+```
+$ cd multi-cluster-app-dispatcher/deployment/
+dianaarroyosmbp:deployment darroyo$ ./build.sh 
+...
++ cd ..
++ make generate-code
+Compiling deepcopy-gen
+Generating deepcopy
+go build -o _output/bin/deepcopy-gen ./cmd/deepcopy-gen/
+_output/bin/deepcopy-gen -i ./pkg/apis/controller/v1alpha1/ -O zz_generated.deepcopy 
++ make kar-controller
+mkdir -p _output/bin
+CGO_ENABLED=0 GOARCH=amd64 go build -o _output/bin/kar-controllers ./cmd/kar-controllers/
+$
+```
+
+Ensure the executables: `deepcopy-gen`, `kar-controllers` are created in the target output directory:
+```
+$ ls ../_output/bin/
+deepcopy-gen	kar-controllers
+$
+```
