I just renamed `my-repository` to `my-repository.git`. Ugly hack from [1] but
it works.

It didn't changed and I don't want to use that. (It works for me locally but

Hello,

I do have a beginner question. Is it possible to build a docker image directly
from the sr.ht? If so, how?

I do:

    $ docker build -t www https://git.sr.ht/~qeef/damn-www

That returns the error:

    Sending build context to Docker daemon  17.41kBs://git.sr.ht/~qeef/damn-www 15.59kB
    Error response from daemon: Dockerfile parse error line 1: unknown instruction: <!DOCTYPE
