set up your own website

register your own domain name

I used IONOS

sign up your cloudflare account

Then set up the name server in IONOS according to Cloudflare's instruction

sign up your Github account

And create a new repository then clone to local to develop. I would use VS Code as the developing tool

Static website generator

Tried Jekyll & Pelican, chose Pelican as my tool since it's easier to install and more straightfoward to use. Also there are many Pelican Themes available on Github.

publish the github repository to Cloudflare pages

In Cloudflare, publish the Github repository (Pelican output folder) to Pages, assign a custom domain by using the domain name you registered.
