+# Edge Orchestration on Orange Pi 3
+
+[![Orange Pi 3](orange_pi3.jpg)](http://www.orangepi.org/Orange%20Pi%203/)
+
+## Preparing Orange Pi 3 board
+
+#### 1. Creating an image and writing Orangepi on a SD card
+1. Download Ubuntu image for Orange Pi 3 from (http://www.orangepi.org/downloadresources/).
+2. To install the Orangepi operating system follow the [instructions](http://www.orangepi.org/Docs/SDcardinstallation.html).
+
+> SD card must be at least 16 Gb
+
+#### 2. Start Orange Pi 3
+
+Insert the SD card into the Orange Pi 3 and turn on the power. Make configuration settings for the Orange the first time you turn it on.
+
+---
+
+## Quick start
+This section provides how to download and run pre-built Docker image without building the project.
+
+> TBD
+
+---
+
+## How to build
+There are two options for building a edge-orchestration container:
+1. On your PC and downloading the edge-orchestration container image from the `edge-orchestration.tar` archive (recommended).
+2. Build directly on the Orange Pi 3 board.
+### 1. Using your PC
+
+Prerequisites: install the qemu packages
+```shell
+$ sudo apt-get install qemu binfmt-support qemu-user-static
+```
+
+Run the `./build.sh` script and specify the build parameters - `container`,  architecture - `arm64`  (in the case of building in protected mode, add `secure`), see examples below:
+```shell
+$ ./build.sh container arm64
+```
+or for protected mode:
+```shell
+$ ./build.sh container secure arm64
+```
+the build result will be `edge-orchestration.tar` archive that can be found `bin/edge-orchestration.tar`
+
+Next, need to copy `edge-orchestration.tar` archive to the Paspberry Pi 3 board, install the docker container (see [here](../x86_64_linux/x86_64_linux.md#Build-Prerequisites) only docker part) and load the image using the command:
+```shell
+$ docker load -i edge-orchestration.tar
+```
+The build is finished, how to run see [here](../x86_64_linux/x86_64_linux.md#how-to-work). If you find the issue with Curl Example then please reboot board and run Edge Orchestration container again.
+
+### 2. Build directly on the Orange Pi 3 board
+#### Build Prerequisites
+- docker
+
+```sh
+$ sudo update-alternatives --set iptables /usr/sbin/iptables-legacy
+$ sudo update-alternatives --set ip6tables /usr/sbin/ip6tables-legacy
+$ curl -sSL https://get.docker.com | sh
+$ sudo usermod -aG docker $USER
+$ newgrp docker
+```
+
+> For [execution of docker commands with non-root privileges](https://docs.docker.com/install/linux/linux-postinstall/#manage-docker-as-a-non-root-user) you need to add `$USER` to docker group.  
+`$ sudo usermod -aG docker $USER`
+
+- go compiler (install a version not lower than 1.12.5)
+
+```sh
+$ wget https://dl.google.com/go/go1.16.2.linux-arm64.tar.gz
+$ tar -C $HOME -xvf go1.16.2.linux-arm64.tar.gz
+$ export GOPATH=$HOME/go
+$ export PATH=$PATH:$GOPATH/bin
+```
+
+- edge-orchestration source code
+
+```sh
+$ git clone https://github.com/lf-edge/edge-home-orchestration-go.git
+
+```
+The build is described [here](../x86_64_linux/x86_64_linux.md#how-to-build).
+
+The build is finished, how to run see [here](../x86_64_linux/x86_64_linux.md#how-to-work).
