How to build Atom for Slackware?

Who kept repository for him gave up.
From an old Slackbuild it is impossible to compile it.
On the Atom Site I just found wrong information, even the download informed by github doesn’t work.

I downloaded Source from here:

If anyone can help with information such as:
What dependencies must be installed for it to be compiled?
What is necessary?

Because without this information, I will have to give up this Editor, because the version I’m using is too old!

Not even the compiled version of Atom works correctly!

I liked the Editor because of some functions I learned that are very useful for me, like snippets, grammars. But if I can’t use it won’t do me!
