+- Inside your Yunohost LXC/ynh-dev/???, make sure the new `yunohost-portal-api` service is running and corresponding route is in nginx config
+- **Important**: Inside your Yunohost machine, enable CORS from your dev front-end:
+    - `echo "http://127.0.0.1:3000" > /etc/yunohost/.portal-api-allowed-cors-origins`
+    - `systemctl restart yunohost-portal-api`
+- Back to Yunohost-portal's repo: define what's the IP / domain of your test LXC where the API lives (here, for example, `yolo.test` which is define in `/etc/hosts`):
+    - `echo 'NUXT_PUBLIC_API_IP=yolo.test' > .env`
 - `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

 ### 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`
+- Basically the same stuff, but ignore docker-related steps. Instead:
+- You'll need NodeJS 18.14 (or higher) and `yarn`
 - Run `yarn install`
 - Run `yarn dev`
