+
+# Overview
+
+`goSDN` is also an application that will allow you to manage your multi-vendor network using one unified controller.
+
+`goSDN` provides:
+* Model driven device representation
+* Native multi vendor support
+* Multi controller environments
+
+## Example
+A simple showcase how the controller can be adressed after `make containerlab-start` is shown below:
+
+![](gosdn-cli-showcase.webm)
+
+## Structure
+
+- The `api` is a representation of the `controllers` Northbound-Interface and
+  can be used to communicate with the `controller`.
+- The `cli` is the CLI to manage the `controller`.
+- `csbi` is the implementation of Containerised-Southbound-Interfaces (based on
+  the idea and the proof of concept of Manuel Kieweg). Allowing to request
+  capabilities of ONDs and generate a containerised Southbound-Interface based
+  on them.
+- `controller` represents the `goSDN-controller`.
+
+# Concepts
+
+The `goSDN` controllers core - also called `nucleus` - is a lightweight library that
+manages principal network domains and provides southbound interface operations
+for orchestrated networking devices.
+
+In addition we provide a simple Northbound-API for the controller ()
+
+## Principal Networking Domain (PND)
+
+The PND is the single source of truth within a network. Its state is held and
+maintained by the controller. Any configuration of an OND has to be applied by
+the PND.
+
+## Orchestrated Networking Device (OND)
+
+Any device directly configured by `goSDN`
+
+# Installing
+`goSDN` provides a `Makefile` for all common use cases.
+
+```sh
+# build the application files for goSDN, cSBI orchestrator, gosdnc (CLI).
+make build
+
+# build the Dockerfiles for goSDN, cSBI orchestrator, gosdnc (CLI).
+make container
+```
+
+Now you can start `goSDN` locally by moving to the `artifacts` folder and
+running `./gosdn` from the shell.
+
+# Getting Started
+
+If you want to use the the [playground](#playground) you have to make sure you have
+[containerlab](https://containerlab.dev/install/) installed on your system.
+
+## Playground
+
+With the help of [containerlab](https://containerlab.dev/) we provide a simple
+test environment to play around with.
+
+The environment contains two [Arista
+cEOS](https://www.arista.com/en/products/software-controlled-container-networking),
+a goSDN, a cSBI orchestrator and a gNMI target.
+
+```sh
+# starts the containerlab topology which contains two Arista cEOS, an cSBI orchestrator, a goSDN controller and gNMI target.
+make containerlab-start
+
+# stop the containerlab topology
+make containerlab-stop
+```
+
+## CLI
+Information about how to use the CLI is provided in the `cli` folder, see [here](cli#usage).
