+A ticket system with backend and frontend components.
+
+## Components
+
+- **[Backend](../backend/index.html)** - The server-side API and business logic
+- **[Frontend](../frontend/index.html)** - The client-side user interface
+
+## Usage
+### Prerequisite
+#### IMPORTANT
+Before compiling the programm you have to install the rust toolchain. 
+For a guide to do this, visit: <https://rust-lang.org/tools/install/>
+
+A instance of a postgresql has to be accessible to the backend. Place the connection details in a .env file into the variable `DATABASE_URL`
+To setup the tables you either can create them manually by following the sheme specified in `backend/migrations` or apply them with sqlx
+To install sqlx run `cargo install sqlx` and then in the `backend` directory run `sqlx migrate run` to create the tables
+
+### Environment
+The .env file has to be in the root directory of the project or in the same directory as the executable
+
+Keys:
+`DATABASE_URL`: Specifying the url and connection details for the database
+`TOKEN_SECRET`: The JWT token secret, can theoretically be anything but is more secure when generated with a tool, e.g: <https://jwtsecrets.com/>
+`ORIGIN`: The origin of the frontend, used for CORS rules
+`BACKEND_PORT`: The port which the backend should use to run on
+
+### Backend
+The backend can either be run via `cargo run --release` or `cargo build --release` using the correct target architecture, e.g. 'x86_64-unknown-linux-gnu', 
+the executable will be placed in the `target/release` directory and can then be run via any method
+
+### Frontend
+The HTML code for the frontend can be generated by using `trunk build`. The resulting files will end up in the `frontend/dist` directory and can be served over any webserver supporting wasm
+#### NOTE
+To install trunk run `cargo install trunk`
+
+#### IMPORTANT
+Requests from the frontend to /api/* have to be proxied to the Backend
+Example with nginx and frontend running at localhost:8000 and backend at localhost:9000 :
+```nginx
+location /api/ {
+  proxy_pass http://localhost:9000/api;
+}
+```
+
+
+## Usage of AI
+
+Github Copilot CLI was used with the model Claude Haiku 4.5 to generate most of the documentation
+
+Google Antigravity generated the Sequence Diagrams
+
+### Prompt 
+Generate comments for cargo doc describing the indivilual components and create links to relevant structs, functions etc.
+
+Generate a sequence diagramm in @[README.md] behind the class diagramms
+
+### Output
+The comments with `///` or `//!`
+I've gone over it and modified it to my needs and opinions
+
+The general structure sequence diagrams above. I've modified and fixed any errors and discrepancys

+### Frontend
+The HTML code for the frontend can be generated by using `trunk build`. The resulting files will end up in the `frontend/dist` directory and can be served over any webserver supporting WASM
+
+Alternatively download the fontend files from the 'Releases' Page and serve them via any webserver supporting WASM
+> [!NOTE]
+> To install trunk run `cargo install trunk`
+
+> [!IMPORTANT]
+> Requests from the frontend to /api/* have to be proxied to the Backend
+> Example with nginx and frontend running at localhost:8000 and backend at localhost:9000 :
+> ```nginx
+> location /api/ {
+>   proxy_pass http://localhost:9000/api;
+> }
+> ```
