+# Development Container
+
+This is **Devcontainer** configuration to provide a consistent development environment for all contributors.
+
+## Features
+
+- [x] Pre-configured **Python environment**
+- [x] Automatic installation of **pre-commit hooks**
+- [x] **Ruff** linter ready to check your code
+- [x] **Oh My Zsh** with plugins:
+- `zsh-autosuggestions`
+- `zsh-syntax-highlighting`
+
+## Usage
+
+1. Install [**Docker** ](https://www.docker.com/get-started/) and [**Visual Studio Code**](https://code.visualstudio.com/)
+2. Install the **Remote - Containers** extension in VS Code
+
+    - Do `CTRL+P`, paste this command and press `Enter`
+
+        ```shell
+        ext install ms-vscode-remote.remote-containers
+        ```
+3. Open this repository in VS Code
+4. When prompted, click **"Reopen in Container"**
+5. Wait for the environment to build and initialize
+
+After setup:
+
+- `pre-commit` hooks are installed
+- `ruff` and other tools are available
+- The shell uses Zsh by default
+
+## Tips
+
+To manually run checks on all files:
+
+```bash
+pre-commit run --all-files
+```
+
