 # NDI Directory Service
+## Introduction
 The NDI Directory (Discovery) Service is a service used to allow NDI devices to discover each other on a corporate network where mDNS is not allowed. It is available from the NDI SDK.
 
 I have put this into a Docker container, which is available on [Docker Hub](https://hub.docker.com/r/radialbog9/ndi-directory-service).
 
-By using this container you accept the [NDI SDK license agreement](https://downloads.ndi.tv/SDK/NDI_SDK/NDI%20License%20Agreement.pdf)

+## Building
+1. Clone the repo: `git clone https://git.rb9.xyz/TheJoeCoder/ndi-directory-service && cd ndi-directory-service`
+2. Download the SDK, either using `./setup.sh`, or by downloading and running the setup script from [NDI's SDK page](https://ndi.video/download-ndi-sdk/).
+3. Edit `build.sh` and remove `--push` from the `extra_args=` line to disable pushing to Docker Hub.
+4. Build for all architectures using `./build.sh`.
