 ## Setup
 
 - Installer le [package FSV](https://industriels.sesam-vitale.fr/group/fournitures-sesam-vitale)
-- Ajouter le path des librairies FSV à `LD_LIBRARY_PATH` : `export LD_LIBRARY_PATH=/path/to/your/library:$LD_LIBRARY_PATH`
+    - Linux : ajouter le path des librairies FSV à la variable d'environnement `LD_LIBRARY_PATH` avant execution
+    - Windows : ajouter le path des librairies FSV à la variable d'environnement `PATH` avant execution
 
 - Installer la [CryptolibCPS](https://industriels.sesam-vitale.fr/group/galss-cryptolib-cps)
     - Fourni l'utilitaire "CPS Gestion" pour obtenir des informations sur le lecteur de carte, etc.
-        - Linux : `cpgeslux`
\ No newline at end of file
+        - Linux : `cpgeslux`
+
+- Créer un fichier `.env` en s'inspirant d'un des fichiers d'exemple (`.env.linux.example`, `.env.win.example`...)
+
+## C Compilation
+
+Pour compiler les fichiers de librairie :
+
+- Windows : `.\build.bat`
+- Linux : `make`
+
+Pour nettoyer le dossier `./lib` :
+
+- Windows : `.\build.bat /clean`
+- Linux : `make clean`
