+
+## 1. Introduction
+This document provides a description of how to add a new platform to the Edge-Orchestration project.
+
+## 2. Add a new platform
+First of all, you can familiarize yourself with the [Raspberry Pi 3 example](./platforms/raspberry_pi3/raspberry_pi3.md) and do the same.
+Porting a new platform is a simple process with three main parts.
+
+### 2.1 Additional code structure
+
+You must first create a directory with the name of your platform `<new platform name folder>`, a file with description `<name_platform>.md` and a picture of the platform `<name_platform>.png`. Example see below:
+```
+...
+├── docs
+│   ├── platforms
+│   │   ├── <new platform name folder>
+│   │   │   ├── <name_platform>.md
+│   │   │   └── <name_platform>.png
+│   │   ├── raspberry_pi3
+│   │   │   ├── raspberry_pi3.jpg
+│   │   │   └── raspberry_pi3.md
+...
+
+```
+#### 2.1.1 <name_platform>.md
+The following aspects need to be described in this file:
+ * Describe how to create or where to download a Linux image.
+ * How to start and configure Linux (network configuration if required).
+ * How to download and run pre-built Docker image (`edge-orchestration.tar`) without building and/or describe the procedure for how to build `edge-orchestration.tar` directly on the board.
+ * Describe the procedure for launching a docker on the board without root permission.
+
+ >  The above points are required. If you have additional information, you can provide it without hesitation.
+
+#### 2.1.2 <name_platform>.png
+The requirement for this file is as follows:
+ * Display the board at an angle to make it easy to recognize.
+ * Size no more than 150 pixels in width or height.
+ * Picture format `png` or `jpg`.
+ * Preferably white background.
+
+### 2.2 Update README.md
+There is a section [3. Platforms Supported](https://github.com/lf-edge/edge-home-orchestration-go#platforms-supported) which lists all devices that are supported in the Edge-Orchestration, you must add your platform by specifying a link to the description and picture of the platform.
+You also need to add a platform description into [Quick start guides for supported platforms](https://github.com/lf-edge/edge-home-orchestration-go#quick-start-guides-for-supported-platforms)
+where:
+ * **Platform** - platform name and link to quick start guide
+ * **Maintained** - version or repository tag the Edge-Orchestration was tested latest
+ * **Maintainer** - contact person who can help to run Edge-Orchestration on the this platform
+ * **Remarks** - additional important information
+
+## 3. Code inclusion to Edge-Orchestration upstream
+We do encourage everyone to submit their board support to the edge-orchestration project itself, so it becomes part of the official releases and will be maintained by the edge-orchestration community itself. If you intend to do so, then there are a few more things that you are supposed to do.
+
+If you are submitting the board support upstream and cannot give Edge-Orchestration maintainers your platform, then we are going to ask you to become the maintainer of the platform you have added. By being a maintainer for the platform you are responsible to keep it up to date and we will be ask to test every the Edge-Orchestration release on your platform.
