Hello, can I download this website program to build it?

[GuguguBear]

I really like this website program, it provides many functions that are convenient for players, but in our region, accessing it is too slow, I hope to be able to build a local server to operate this website, I saw it appear on Github I would like to ask if there is a more detailed process to build it.

Or is this website program not open source?

Thank the authors for their efforts and love you.
