-## Requirements
+# Krys4lide
 
-- 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)
+Logiciel de Pharmacie libre et open-source.
 
-- 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 : `...`
+## Crates
 
-## Setup
+- `app`: Interface du logiciel, servie par un serveur web propulsé par Axum. Utilisable en mode endpoint ou encapsulé dans le client `desktop`
+- `desktop`: Client desktop propulsé par Tauri, encapsulant le serveur web `app`
+- `sesam-vitale`: Bibliothèque de gestion des services SESAM-Vitale (Lecture des cartes CPS et Vitale, téléservices ...)
 
-- 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
+## Development
+
+### Pré-requis
+
+La CLI Tauri est nécessaire au lancement du client `desktop`. Elle peut être installée via Cargo :
+
+```bash
+cargo install tauri-cli
+```
+
+### Exécution de l'application cliente desktop
+
+```bash
+cargo tauri dev
+```
+
+### Exécution du serveur web `app` en mode endpoint
+
+```bash
+cargo run --bin app 
+```
 
 ## Build
 
-### Compilation C
+Packager le client desktop
 
-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`
-
-Pour compiler les fichiers de librairie :
-
-- Windows : `.\make.bat`
-- Linux : `make`
-
-Pour nettoyer le dossier `./lib` :
-
-- Windows : `.\make.bat /clean`
-- Linux : `make clean`
-
-### Compilation Rust
-
-`cargo build`
-
-## Run
-
-`cargo run`
+```bash
+cargo tauri build
+```

+## Build
+
+### Windows - Compilation des headers FSV
+
+Sous windows, la librairie dynamique fournie par le package FSV nécessite des headers qui ne sont pas présents dans la `.dll`. Il est donc nécessaire de fournir ces headers, en les renseignant dans des fichiers `crates/sesam-vitale/src/win/fsv/*.def` qui seront compilés en leur version binaire `crates/sesam-vitale/lib/*.lib`.
+
+En cas de modification des fichiers `.def`, pour re-compiler ces headers, faire appel au script `scripts/compile_win_headers.bat`.
+
+| /!\ Attention, le script `compile_win_headers.bat` exécute, en interne, l'utilitaire `vcvarsall.bat` et le linker `lib.exe` de Visual Studio. Visual Studio doit donc être installé et le chemin vers l'intallation le script `vcvarsall.bat`, écrit en dur dans le script `compile_win_headers.bat` doit être adapté à votre installation.
+
+## À creuser
+
+- Compilation cross platform facilitée par du Docker : https://github.com/cross-rs/cross
+- Pour éviter l'usage de dotenv pour la configuration, on peut utiliser https://direnv.net/
