 In order to use it you must mount the scaleway configuration file:
 ```sh
-docker run -it --rm -v $HOME/.config/scw:/root/.config/scw scaleway/cli:v2.3.0
+docker run -it --rm -v $HOME/.config/scw:/root/.config/scw scaleway/cli:v2.26.0
 ```
 
 If you want to use `scw` instead of `docker run` you can add the following in your `~/.bashrc`:
 ```bash
 scw() {
-    docker run -it --rm -v $HOME/.config/scw:/root/.config/scw scaleway/cli:v2.3.0 "$@"
+    docker run -it --rm -v $HOME/.config/scw:/root/.config/scw scaleway/cli:v2.26.0 "$@"
 }
 export -f scw
 ```
 
 Or if you use ZSH, add the following in your `~/.zshrc`:
 ```zsh
 scw() {
-    docker run -it --rm -v $HOME/.config/scw:/root/.config/scw scaleway/cli:v2.3.0 $@
+    docker run -it --rm -v $HOME/.config/scw:/root/.config/scw scaleway/cli:v2.26.0 $@
 }
 ```
 
+## Use your ssh-key
+
+In order to use your ssh-key you must mount your .ssh folder
+```sh
+docker run -it --rm -v $HOME/.config/scw:/root/.config/scw -v $HOME/.ssh:/root/.ssh scaleway/cli:v2.26.0 $@
+```
+
+You can then ensure that your ssh key is present in your Scaleway account
+```sh
+scw iam ssh-key init
+```

 ## Autocompletion
 
 You can still use autocompletion while running the CLI in Docker, you just need to modify script generated by the CLI.
