 ## How to setup
 
-### Linux environment
+### Docker environment
 
-_I need to add this part, via a dedicated Bash script_
+You can download the Dockerfile and build the image yourself, or simply pull it from the repo:
+```bash
+docker pull ghcr.io/adipeterca/curier:latest
+docker run -p 8080:8080 ghcr.io/adipeterca/curier:latest
+```
 
-### Windows environment
+### Linux environment
 
-_I need to add this part, via a dedicated Powershell script_
+**I strongly recommend using Docker, as it simplifies the configuration a lot**.
 
-### Docker environment
+If you want to use a precompiled binary, please refer to the [Release](https://github.com/adipeterca/curier/releases) section.
+
+### Windows environment
 
-_I need to add this part, either as a Dockerfile or an already built container_
+Because not many servers run Windows, the support I can provide for this platform is limited.
+You can download a precompiled binary from the [Release](https://github.com/adipeterca/curier/releases) section or use a Docker container.
 
 ## Configuration
 
-You can configure some aspects of the service via environment variables prefixed with **CURIER_**.
-| Variable name | Default value | Description |
-|--|--|--|
-|`CURIER_STORAGE_PATH`|`/var/lib/curier/uploads/` (Linux/Docker), `?` (Windows)|Absolute path where the file uploads will be stored on disk|
-|`CURIER_BASE_URL`|`http://localhost`|Default prefix for the `/download/{id}` URL|
-|`CURIER_HOST`|`127.0.0.1`|Network address to bind to|
-|`CURIER_PORT`|`8080`|Port to use|
+You can configure some aspects of the service via environment variables prefixed with **CURIER_**.  
+Some information will be exposed via the `/config/` endpoint for better UX.  
+For default values, check [config.go](https://github.com/adipeterca/curier/blob/main/config.go).
