letsencrypt will ask you to provide an email address and your domain. It will then save your certificates in /etc/letsencrypt/live/example.com/ where example.com is your domain.
As last step we have to tell twister-proxy where the certificates are
```
nano twister-proxy/settings.json
```
Inside "Server" replace example.com by your domain in a the "ssl_*" properties. Press Crtl+O to save and then Crtl+X to exit.
Now we can start it up. When starting for the first time it will pull the twister docker-image.
```
./run.sh
```
twisterd now needs a while (10min to 1h depending on your connection) to download the blockchain. You can check `top` to see if twisterd is still busy.
