How install Lemmy 0.17 version?

I wanna be back for develop another UI for Lemmy, which will look like modern Reddit, but better.

Earlier i install lemmy with this guide: https://www.youtube.com/watch?v=4fzCUEpFnDg

but now, devs made changes around nginx, so... i cant install Lemmy now. Docker sends me errors))

If you are interested in developing a new UI, please contact me, I need the help of people who understand the installation issue.
