 If you don't need to connect to Verboice nor Nuntium, you can move forward with this setup.
 
 1. You need to use [dockerdev](https://github.com/waj/dockerdev) to access the web app at `app.surveda.lvh.me` and ngrok at `ngrok.surveda.lvh.me`.  Just follow the project's readme.  **WARNING:** You should install `dockerdev` _before_ creating your stack's network in Docker. If you have already run `./dev-setup.sh`, you may want to run `docker compose down -v` to **delete every container, data and other artifacts** from the project and start from scratch _after_ running `dockerdev`.
+Make sure you use the right `dockerdev` image `docker pull --platform linux/arm64 manastech/dockerdev`
 2. Clone this repository.
 3. In the project's root, execute `./dev-setup.sh`.
 4. Start the app with `docker compose up`.
