Let me be real with you: most guides about this topic are outdated or just wrong. Here is what actually works in 2026.
Step-by-step
I am going to walk through this exactly as I did it, including the parts where I got confused and had to backtrack. Because that is the reality of working with new tools.
Prerequisites: a working setup of whatever platform you are using (I use OpenClaw but the concepts apply broadly), about 30 minutes of uninterrupted time, and maybe a second monitor for the docs.
The numbers
I hate vague advice. Here are actual numbers from my setup. Your setup will differ, but at least you have a reference point instead of someone saying “it depends” for the fifth time.
The gotchas
Three things that will trip you up if you are not ready for them. First: permissions. Always check permissions first when something does not work. Second: caching. Clear it. Clear it again. OK now it works. Third: documentation lag. The docs are often one version behind. When in doubt, check the source code.
TL;DR: start simple, measure everything, iterate based on data not feelings. The Docker Docs, Node.js Docs docs are worth reading if you want to go deeper. Also worth checking: clawgo.net, clawdev.net.
