 ## Usage
 
+The idea is to have the least overhead possible to spawn and interact with a Katana instance. So no client is designed for now,
+and you can use very common tools like `curl`.
+
 1. Start an instance
    ```bash
    curl -H 'Content-Type: application/json' \
         -H 'Authorization: Bearer my-key' \
-        https://katana-ci.arkproject.dev/start

-   # Returns a name:
+   # Returns a simple string with the name of the created instance.
    4f2b3c60ae32
    ```
    The start will return an instance `name`, that can then be used to target Katana for this specific instance.

 2. Use `starkli` to interact with the instance, for example:

+   starkli block --full --rpc https://<your_backend_url>/<name>/katana
    ```
 
 3. To check the logs, you can hit the endpoint `/logs` of your instance, by default it returns `25` tail lines. You can use `all` or any number you like using the query parameter `n`.
    ```bash
    curl -H 'Content-Type: application/json' \
         -H 'Authorization: Bearer my-key' \
-        https://katana-ci.arkproject.dev/<name>/logs
