I’d suggest learning what docker is and how to use it if you are trying to host it which is “installing” a web page.

If you want an icon to go to a dedicated window (web app experience) there are lots of options with lots of advantages and disadvantages. Just research progressive web apps. This method is going to require the frontend be hosted so you either need an instance that is using this frontend or you need to host it yourself.

Also to let you know. You’re getting downvotes because this is a very lazily asked question. You didn’t link to what it is you need help with, you asked the question in a manner that suggests you have done no research.

No hate since everyone is a beginner but I really suggest you spend a little more time crafting your questions to the community. Also read a little on docker and how lemmy front ends work.

In the meantime this should help you get started.

Docker Official Documentation

Afterwards go to the git repo of this ~~”app”~~ pages source code. There is a one command solution to deploy it.

Mlmym GitHub

As long as docker is installed and set up you should just be able to enter the command for the deployment to get it running.

Go to http://localhost:8080 or if that doesn’t work https://localhost:8080 in your browser as indicated by the command and there is your front end.
