+# Welcome !
+
+## This website
+
+The idea behing this website is to be a place where I can share my experiments, issues, 
+how I resolved them, essays, thoughts and anything else that could be useful for anyone 
+other than me. (Which could be myself from the future!).
+
+Thus I chose to make it a blog (the sources of which can be found 
+[here](https://git.tfk-astrodome.net/Teo-CD/TFK-Blog)) which might not be well structued 
+or planned but -- idealy -- at least organized by category/theme !
+
+This blog is created with [Zola](https://www.getzola.org/) an uses a custom version of the [Zulma](https://www.getzola.org/themes/zulma/) theme.

+## This guy
+
+I'm trotFunky (Shortened `trot`. Or Téo, but trotFunky is alright). I'm a French guy, 
+born in 1998 (That's easier to keep updated than an age), (soon to be) gratuated from 
+l'[Institut Polytechnique de Paris](https://www.ip-paris.fr) who likes to tinker, code 
+and play tabletop RPGs. Low-level programmer at the robotics club INTech for three years. 
+Apparently, a blogger.
+
+## Astrodome ?
+
+What a strange name ! Merriam-Webster defines an "astrodome" as follows :  
+> A transparent dome in the upper surface of an airplane from within which the navigator makes celestial observations
+
+I chose this noun for my URL as I picture my different services as multiple stars in 
+galaxy/constellation that is mine. The Astrodome allows observing this constellation !
