QMK noob question

[OhManIAmWorried]

My Delux m618 is now dead for reasons unknown to me, it's time to add mouse functionality to my board.

To this day I was using http://kbfirmware.com/ in coop with layout editor, but, unfortunately, keymap thing doesn't have the keycodes for the mouse (KC_MS_...). On this page https://docs.qmk.fm/mouse_keys.html I've read that the makefile file should be changed, and here is the question: how to get this file? I see only .hex and .json files.

I'll read github page on QMK to find out how to make files using IDE but I'm not sure that my knowledge will be enough  , so some clear step by step instructions are highly apreciated. Please help.

Upd: I guess I've missed a huge chunk of work by using that tool. If anyone had made a thread about making stuff hard way, please, give me a link.

QMK is provided as source code and you have to compile it yourself to get the most out of it.
If I myself can make it, it's not that hard to edit files and set an environment up for this purpose.

Anyway, QMK isn't the only keyboard firmware around here. Have you had a look at EasyAVR?

No, only heard of it. I'll try to search for guides on QMK and If I don't succeed in a couple of hours I'll try EasyAVR. Thanks for suggestion!

After all, I always wanted to write (partly, at least) the code by myself. If anything, this makes my DIY keyboard even more DIY

Is there a way to make a custom layout in EasyAVR? My layout doesn't correspond to any of those keyboards.
