-Ječná Rozvrh API má svoji Rust knihovnu pro komunikaci s API. Obsahuje mappings pro Kotlin. Pro další jazyky budou mappingy v budoucnu.
-
-## Usage
-
-### `JecnaSuplClient` struct
-
-Knihovna používá `JecnaSuplClient` struct. Vytvoříte instanci pomocí `new`.
-
-```rust
-fn main() {
-    let client = JecnaSuplClient::new();
-}
-```
-
-### `set_provider(url: String)`
-
-Pokud nenastavíte vlastní provider path API použije hosted `https://jecnarozvrh.jzitnik.dev`
-
-Example usage:
-
-```rust
-client.set_provider("https://jecnarozvrh.example.com");
-```
-
-### `get_schedule(class_name: String) -> Result<SuplResult, SuplError>`
-
-Example usage:
-
-```rust
-let class = String::from("C2c");
-match client.get_schedule(class) {
-    Ok(result) => {
-        println!("Last update: {}", result.status.last_updated);
-    }
-    Err(error) => {
-        panic!("Error: {}", error)
-    }
-}
-```
-
-### `get_teacher_absence() -> Result<TeacherAbsenceResult, SuplError>`
-
-Example usage:
-
-```rust
-match client.get_teacher_absence() {
-    Ok(result) => {
-        /* Code */
-    }
-    Err(error) => {
-        panic!("Error: {}", error)
-    }
-}
-```
-
-### `get_all() -> Result<ApiResponse, SuplError>`
-
-Example usage:
-
-```rust
-match client.get_all() {
-    Ok(result) => {
-        /* Code */
-    }
-    Err(error) => {
-        panic!("Error: {}", error)
-    }
-}
-```
-
-### `report(content: String, class: String, report_location: ReportLocation) -> Result<(), SuplError>`
-
-Report function for reporting errors of the parser to the provider.
-
-Example usage:
-
-```rust
-let content = String::from("Detailni popis chyby");
-let class = String::from("C2c");
-let report_location = ReportLocation::Timetable;
-
-match client.report(content, class, report_location) {
-    Ok(result) => {
-        println!("Success");
-    }
-    Err(error) => {
-        panic!("Error: {}", error)

-Tento projekt je možné hostovat vlastním způsobem, ať už pomocí Dockeru nebo nativně.
-
-## Požadavky
-
-Před začátkem se ujistěte, že máte připravené následující:
-
-- **Účet SPŠE Ječná**: Projekt vyžaduje platný školní e-mail a heslo pro přístup k tabulce na SharePointu.
-- **Node.js 22+**: Pokud hostujete nativně.
-- **Hugo**: Pro sestavení a provoz webového rozhraní.
-- **Chromium/Puppeteer**: Pro automatizované stahování dat.
-
-## Způsoby hostování
-
-### Docker (Doporučeno)
-
-Použití Dockeru je nejjednodušší způsob, jak projekt spustit, protože automaticky řeší všechny závislosti včetně prohlížeče pro Puppeteer.
-
-1. **Klonování repozitáře**:
-   ```bash
-   git clone https://gitea.local.jzitnik.dev/jzitnik/jecnarozvrh.git
-   cd jecnarozvrh
-   ```
-
-2. **Konfigurace**:
-   Upravte soubor `docker-compose.yml` a doplňte své přihlašovací údaje:
-   ```yaml
-   services:
-     app:
-       environment:
-         - EMAIL=vas-email@spsejecna.cz
-         - PASSWORD=vase-heslo
-   ```
-
-3. **Spuštění**:
-   ```bash
-   docker-compose up -d --build
-   ```
-
-Aplikace bude dostupná na portu `3000`.
-
-> **Poznámka k webu v Dockeru**: Výchozí Docker image má `SERVE_WEB` nastaveno na `false`, protože neobsahuje Hugo pro sestavení webové části. Docker verze primárně slouží jako API server.
-
-### Nativní instalace
-
-Pokud nechcete používat Docker, můžete projekt spustit přímo na svém systému.
-
-1. **Instalace závislostí**:
-   ```bash
-   npm install
-   ```
-
-2. **Sestavení projektu**:
-   Tento krok zkompiluje TypeScript a sestaví Hugo web.
-   ```bash
-   npm run build
-   ```
-
-3. **Nastavení proměnných prostředí**:
-   Vytvořte soubor `.env` v kořenovém adresáři:
-   ```env
-   EMAIL=vas-email@spsejecna.cz
-   PASSWORD=vase-heslo
-   PORT=3000
-   ```
-
-4. **Spuštění**:
-   ```bash
-   npm run serve
-   ```
-
-## Environmental variables
-
-| Proměnná | Popis | Výchozí hodnota |
-|----------|-------|-----------------|
-| `EMAIL` | Školní e-mail pro přihlášení. | - |
-| `PASSWORD` | Heslo k e-mailu. | - |
-| `SHAREPOINT_URL` | Odkaz na Excel tabulku na SharePointu. | *Předdefinovaný odkaz na nástěnku* |
-| `PORT` | Port, na kterém server poběží. | `3000` |
-| `REPORT_WEBHOOK_URL` | URL pro webhook hlášení chyb (Discord/Slack). | - |
-| `SERVE_WEB` | Určuje, zda se má serveovat Hugo web. | `true` |
-
-## Persitence dat
-
-Veškerá stažená data a stav prohlížeče (včetně cookies) se ukládají do složky `volume/`. Při použití Dockeru je důležité tuto složku mapovat jako volume, aby nedocházelo k opakovanému přihlašování a stahování dat při každém restartu.

-Pokud si chcete zobrazit stálý rozvrh zároveň s mimořádným rozvrhem ve webovém rozhraní musíte si získat statický rozvrh. Ten získáte pomocí Node.js scriptu.
-
-## Požadavky
-
-Před začátkem se ujistěte, že máte připravené následující:
-
-- **Účet SPŠE Ječná**: Script vyžaduje platný školní účet a heslo.
-- **Node.js 22+**
-- **Git**
-
-## Stažení projektu
-
-```bash
-git clone https://gitea.jzitnik.dev/jzitnik/jecnarozvrh
-```
-
-## Stažení knihoven a spuštění scriptu
-
-```bash
-npm i
-
-npm run parse-timetable
-```
-
-Script se vás zeptá na username, password a output cestu k souboru.
-
-Script projde všechny učitele a sestaví rozvrh všech tříd podle toho.
