How can I make Atmosphere-compatible IPS Patch?

[Digika]

I'm having hard time following https://gbatemp.net/threads/how-to-create-your-own-sigpatches.616288/

So I have extracted, uncompressed and decompiled/analyzed NSO in IDA (using nxo64.py). Now I want to chage a few bytes (instructions) and make an IPS patch.
How am I supposed to do it? Do I have to produce patched binary (which will be uncompressed) and then use both with patcher?
Or do I need to compress patched binary?
Are there any other caveats?

Yes the patch should be made based on the uncompressed original and the uncompressed modified binaries.
