 Oh, just for fun, and because I love this project, I use [pit by michaeldv](https://github.com/michaeldv/pit) to follow my task etc.
 
 It makes me think I should push my python version of this project on occasion when I will take the time to do...
+
+How to build it?
+----------------
+
+This project use two very cool projets to handle env & build:
+
+- [**just**](https://github.com/casey/just) as an alternative to [GNU Make](https://www.gnu.org/software/make/manual/make.html)
+- [**pixi**](https://github.com/prefix-dev/pixi) to manage python & dependancies environnment without question
+
+You can install these two software by your way, or use the Makefile to do it: `$ make`.
+
+This command will download & untar `just` and `pixie` into a hidden `.bin` folder and launch just target to do the rest.
+
+> Don't forget to set a valid SMTP host/port in `config.ini`. Otherwise, notifier execution will fail. See below if you want to get a wrapper
+
+Just's targets permit to:
+
+- just run the script
+- build a docker image
+- create a release
+- etc.
+
+Use `.bin/just --list` to list all available target.
+
+### Use mailpit to wrap mails
+
+If you don't want to really send and receive mail, e.g. to test... things! I recommand [**mailpit**](https://github.com/axllent/mailpit).
+
+You can quickly get it with just: `.bin/just get-mail-wrapper`.
+
+Then execute-it: `./mailpit`.
+By default, SMTP port is `1025`, and HTTP port to access to interface is `8025`.
