How this blog is build

other

In this post, I’d like to show you how I’ve started with writing this blog. How the process evolved during 3 years of writing. How I’ve finally managed to set up everything in a way that works for me now. If you don’t blog yet this might help you out with technical details on how you can start easily.

In this post, I’m going to show you how you can automate the whole process and save some time doing it with docker.
