Right now I'm pretty confident I can get the hardware in place, when I have everything complete.

I however have no experience with the used OS/software and have zero knowledge in programming.

I'm a little worried, I'm in over my head eventually.
Is there a step for step guide?
Do I need to write down every bit of hardware I've used?
Any tips regarding the build to make the software part easier?

Check the installation guide at https://retropie.org.uk/docs/First-Installation/.

Thanks!

I know next to noting about the software involved bu there are so many guides out there for whatever you wanna do. Ive compleed 2builds and had next to no trouble with software issues.
