 This template demonstrates how you can run MS Dynnamics NAV in [Azure Container Instances](https://docs.microsoft.com/en-us/azure/container-instances/). To find out more about Dynamics NAV inside a Windows Container visit [Github](https://github.com/microsoft/nav-docker)
 
-To start the instance, you need to accept the [end user license agreement](https://go.microsoft.com/fwlink/?linkid=861843) by setting the param acceptEula to Y. Be aware that this is downloading a rather large image (about 15GB), so downloading and extracting it takes about 20 minutes. After it has started, look into the logs to see when it has finished initializing or just wait for a minute. After that you can access Dynamics NAV at https://< ip >/NAV/WebClient

You also need to enter which version of NAV you want to use by setting navRelease (see [this list](https://hub.docker.com/r/microsoft/dynamics-nav/tags/) for possible values).
