+# Picture Uploader
+
+This project is a simple web application written in Go for uploading and viewing images.
+
+## Getting Started
+
+To run this application, follow the steps below:
+
+### Prerequisites
+
+- [Docker](https://www.docker.com/)
+- [docker-compose](https://docs.docker.com/compose/)
+
+### Instructions
+
+1. Clone the repository:
+
+    ```bash
+    git clone <repository-url>
+    ```
+
+2. Navigate to the project directory:
+
+    ```bash
+    cd <project-directory>
+    ```
+
+3. Create a folder named `uploads`:
+
+    ```bash
+    mkdir uploads
+    ```
+
+4. Set permissions for the `uploads` folder:
+
+    ```bash
+    chmod 777 uploads
+    ```
+
+5. Run the application using Docker Compose:
+
+    ```bash
+    docker-compose up -d
+    ```
+
+The application should be accessible at [http://localhost:8080](http://localhost:8080).
+
+## Configuration
+
+Modify the `docker-compose.yml` file to adjust environment variables, ports, or any other configurations as needed.
+
+## Additional Information
+
+- This project uses NGINX as a reverse proxy. Ensure that the required networks (`nginx-proxy` and `edge`) are set up externally or adjust the `docker-compose.yml` accordingly.
+- If you encounter issues with image uploads, verify the permissions on the `uploads` folder.
+
