docs: remove dev version note

Directory makes it more clear of what it is. In addition, this will make it easier when
allowing for multiple directories in the future, since we can just name it 'directories', which is more clear than 'scopes'.

 ## Install
 
-Please refer to the [Releases page](https://github.com/hacdias/webdav/releases) for more information. There, you can either download the binaries or find the Docker commands to install WebDAV.
+For a manual install, please refer to the [releases](https://github.com/hacdias/webdav/releases) page and download the correct binary for your system. Alternatively, you can build or install it from source using the Go toolchain. You can either clone the repository and execute `go build`, or directly install it, using:
+
+```
+go install github.com/hacdias/webdav/v5@latest
+```
+
+### Docker
+
+Docker images are provided on both [GitHub's registry](https://github.com/hacdias/webdav/pkgs/container/webdav) and [Docker Hub](https://hub.docker.com/r/hacdias/webdav). You can pull the images using one of the following two commands. Note that this commands pull the latest released version. You can use specific tags to pin specific versions, or use `main` for the development branch.
+
+```bash
+# GitHub Registry
+docker pull ghcr.io/hacdias/webdav:latest
+
+# Docker Hub
+docker pull hacdias/webdav:latest
+```
 
 ## Usage
 
-`webdav` command line interface is really easy to use so you can easily create a WebDAV server for your own user. By default, it runs on a random free port and supports JSON, YAML and TOML configuration. An example of a YAML configuration with the default configurations:
+For usage information regarding the CLI, run `webdav --help`.
+
+### Docker
+
+To use with Docker, you need to provide a configuration file and mount the data directories. For example, let's take the following configuration file that simply sets the port to `6060` and the directory to `/data`.
+
+```yaml
+port: 6060
+directory: /data
+```
+
+You can now run with the following Docker command, where you mount the configuration file inside the container, and the data directory too, as well as forwarding the port 6060. You will need to change this to match your own configuration.
+
+```bash
+docker run \
+  -p 6060:6060 \
+  -v $(pwd)/config.yml:/config.yml:ro \
+  -v $(pwd)/data:/data \
+  ghcr.io/hacdias/webdav -c /config.yml
+```
