+## Requirements
 
-Logiciel de Pharmacie libre et open-source.
+- Installer le [package FSV](https://industriels.sesam-vitale.fr/group/fournitures-sesam-vitale)
+    - Les librairies dynamiques (.lib, .dll, ...) fournies ne sont pas installés dans les emplacements standard du système, il faudra donc configurer leur chemin d'installation dans le fichier de configuration `.env.build` (voir ci-dessous)
+        - Le détail des chemins d'installation est donné dans la documentation du package FSV `fsv-mi-004_pack-FSV1.40.14_V2.3.pdf`
+            - Linux - par défaut : `/opt/santesocial/fsv/1.40.13/lib`
+            - Windows - par défaut : `C:\Program Files\santesocial\santesocial\fsv\1.40.14\lib` (ou dans Program Files (x86) si c'est le package 32bits qui a été installé)
 
-## Crates
+- Installer la [CryptolibCPS](https://industriels.sesam-vitale.fr/group/galss-cryptolib-cps)
+    - Ce package fourni également l'utilitaire "CPS Gestion" pour obtenir des informations sur le lecteur de carte, etc.
+        - Linux : `cpgeslux`
+        - Windows : `...`
 
-- `clego`: Axum backend lib for tauri client. Can be used as a lib or started as a web server.
+## Setup
-- `tauri`: Tauri app for desktop client.
 
-## Development
+- Créer et éditer le fichier de configuration de build `.env.build` en s'inspirant d'un des fichiers d'exemple (`.env.build.linux.example`, `.env.build.win.example`...)
+    - Ce fichier est nécessaire pour le build du package Rust
+- Créer et éditer le fichier de configuration de l'exécution `.env` en s'inspirant d'un des fichiers d'exemple (`.env.linux.example`, `.env.win.example`...)
+    - Ce fichier est nécessaire pour l'exécution du package Rust compilé, et doit donc être présent aux côtés de l'exécutable généré, le cas échéant
 
-Install
+## Build
 
-```bash
+### Compilation C
-cargo install tauri-cli
-```
 
-Run desktop client app
+Ce package s'appuie sur deux librairies :
+- Une librairie statique, compilée à partir des sources (`*.c`, `*.h`) fournies dans le dossier `./src`
+- Une librairie dynamique, fournie par le package FSV
+    - Windows : on fournit les headers, non présents dans la `.dll` en compilant les fichiers `src/*.def` en leur version binaire `lib/*.lib`
 
-```bash
+Pour compiler les fichiers de librairie :
-cargo tauri dev
-```
 
-Run clego endpoint
+- Windows : `.\make.bat`
+- Linux : `make`
 
-```bash
+Pour nettoyer le dossier `./lib` :
-cargo run --bin clego
-```
 
-Bundle desktop client app
+- Windows : `.\make.bat /clean`
+- Linux : `make clean`
 
-```bash
+### Compilation Rust
-cargo tauri build
+
-```
+`cargo build`
+
+## Run
+
+`cargo run`
