+### Certificates
+The last step to this would be adding certificates. It is not an easy process, but asesidaa made a script that should do it for you.
+
+You can find the script to install the scripts in here:
+[https://github.com/asesidaa/LLServer/tree/master/LLServer/Certificates](https://github.com/asesidaa/LLServer/tree/master/LLServer/Certificates)
+
+Make sure to run the script as administrator. ([you might need to enable powershell script running exception](https://superuser.com/questions/106360/how-to-enable-execution-of-powershell-scripts#106363))
+
+Enter this command in an administrator powershell window:
+
+`set-executionpolicy remotesigned`
+
+If the script doesn't work, you just need to have the certs in the 'Personal' store and the 'Root Trust ...' store (I forget the full name). After that you shouldn't get any nesys HTTP errors (it should just connect).
+
+If the server isn't compiled already, you'll need Visual Studio Community edition, link for easy access [here](https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=Community&channel=Release&version=VS2022&source=VSLandingPage&cid=2030&passive=false).
+Make sure you set it up with basic .NET functionality. (It should install the things it needs if you don't select the right one so don't worry too much).
+
+Then if you haven't already, download the LLServer repo:
+[https://github.com/asesidaa/LLServer/archive/refs/heads/master.zip](https://github.com/asesidaa/LLServer)
