can't pull/build docker-file

[Weissnimma]

#6 Sorry, there is no URL for building the docker-image. I tried things like docker build -t grav:latest https://github.com/getgrav/docker-grav etc in OMV 4, but without success. Could You please update the readme? The image of garywiz/docker-grav unfortunately has some errors, makes no sense to me... Thank You!!

Currently there is no pre-build container available on the Docker Hub from this repository. This repository contains a Dockerfile you need to build yourself.
The Readme.md [currently]https://github.com/getgrav/docker-grav/blob/bddde74c5009639b7f14561363e6826ecc8e01b8/README.md doesn't mention this, but you need to clone this repository to your machine to be able the run the documented build commands.

If this explanation doesn't help you, please supply a more detailed description of what you tried and what kind of errors your were running into.

Additionally I don't see a connection between the Pull-Request 6 you mentioned in your first line and the problem you layed out.

Hi ! I don't know docker well, I'm a simple Grav user and I wanted to run it locally before installing it on a server. I had to find this issue to think about cloning the repo (I had downloaded the dockerfile and run the build command and that wasn't working). I think it should be added to the documentation (but I'm too new to dare suggesting a PR myself).
