+# How to Launch the ML-Logger and dash.ml service
+
+run:
+
+```shell
+screen -S dash -dm bash start-dash.sh
+screen -S logger -dm bash start-logger.sh
+```
+
+
+to check if your server is running, you can inspect the running sessions (screen sessions) via
+
+```shell
+screen -ls
+```
+
+This should show something like this
+
+```
+❯ screen -ls
+There are screens on:
+	21009.zaku	(11/01/24 19:13:19)	(Detached)  * does not apply to you
+	3553.ngrok	(11/01/24 18:49:20)	(Detached)
+	3548.dash	(11/01/24 18:49:20)	(Detached)
+	3545.logger	(11/01/24 18:49:20)	(Detached)
+4 Sockets in /run/screen/S-ubuntu.
+```
+
+and to inspect if the server is *ACTUALLY* running fine:
+
+```shell
+screen -r logger
+```
+
+```{admonition}
+..class:: warning
+If you are attached to the screensession, you will block the server.
+do NOT attach to a server's running session for too long.
+```
+
+To detach from a running session, press <kbd>ctrl</kbd> + <kbd>a</kbd> and then followed with <kbd>d</kbd>.
+
+do NOT press ctrl - D. It will kill the server.
