 - This is a based on [Nuxt v3](https://nuxt.com/)
 
-### Setup
+### Develop (using Docker)
 
-- I'm doing all this from inside a YunoHost LXC
-- You may want to open port 3000 (or disable the firewall) to access the dev server
+- Install Docker
+    - It should boil down to adding something like `deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/debian   bullseye stable` to your apt list
+    - and then `apt update && apt install docker-ce`
+- Install Docker-compose
+    - `pip3 install docker-compose`
+- Inside your Yunohost LXC/ynh-dev/???, make sure the new `yunohost-portal-api` is running and corresponding route is in nginx config
+- Add something like `NUXT_PUBLIC_API_IP=yolo.test` inside a `.env` which you may need to create. Replace `yolo.test` with you test domain or test IP (eg your ynh-dev LXC)
+- `docker-compose up -d` : will rebuild the docker on the first time, then launch it
+- Check `docker-compose logs -f` : should show that nuxt/nitro is building stuff then serving it on port 3000
+- Access `127.0.0.1:3000` from your browser
+
+### Develop (manual / directly on your host machine)
+
+- Same as for Docker, this assumes that `yunohost-portal-api` does run, is configured in nginx, and you may have to set `NUXT_PUBLIC_API_IP` in `.env` which you may have to create
 - You'll need NodeJS 18.14 (or higher)
 - And `yarn`
 - Run `yarn install`
-- Also make sure the new yunohost-portal-api is running and corresponding route is in nginx config
-
-### Dev
-
 - Run `yarn dev`
-- Access `http://1.2.3.4:3000/`
