+# CollabVM Authentication Server
+This is the authentication server for CollabVM. It is used alongside CollabVM server to add support for accounts.
+
+## Prerequisites
+- .NET Core 8.0 or later
+- A MariaDB or MySQL server
+- An SMTP server if you want email verification and password reset
+- An hCaptcha account if you want to use hCaptcha to prevent bots
+
+## Running the server
+1. Clone the source code: `git clone https://git.computernewb.com/collabvm/CollabVMAuthServer --recursive`
+2. Copy `config.example.toml` to `config.toml` and edit it to your liking
+3. Install dependencies: `dotnet restore`
+4. Build the server: `dotnet publish CollabVMAuthServer/CollabVMAuthServer.csproj -c Release --os linux -p:PublishReadyToRun=true`
+5. Run the server: `./CollabVMAuthServer/bin/Release/net8.0/linux-x64/publish/CollabVMAuthServer`
+
+## Setting up NGINX
+You'll want to set up NGINX as a reverse proxy to the authentication server to add HTTPS support. Running the server over plain HTTP is strongly discouraged. Here is an example NGINX configuration:
+```nginx
+upstream cvm-auth { server 127.0.0.1:5858; } # Change the port if you changed the server port in config.toml
+server {
+    listen 80;
+    server_name collabvm-auth.yourdomain.com;
+    location / {
+        # Uncomment if you use Cloudflare proxying
+        #proxy_set_header X-Forwarded-For $http_cf_connecting_ip;
+        # Comment if you use Cloudflare proxying
+        proxy_set_header X-Forwarded-For $remote_addr; 
+        proxy_pass http://cvm-auth;
+    }
+}
+```
+At this point, you should now enable SSL. To do this with LetsEncrypt, you can use `sudo certbot -i nginx -d collabvm-auth.yourdomain.com`
+
+## Integrating with CollabVM
+At this point, you can now integrate the authentication server with CollabVM. You can do this by editing the [auth] section of config.toml. Here is an example:
+```toml
+[auth]
+enabled = true
+apiEndpoint = "https://collabvm-auth.yourdomain.com"
+secretKey = "hunter2" # Change this to the secret key you set in the authentication server's config.toml
+```
+You can then configure [auth.guestPermissions] to set the permissions for guests. Restart CollabVM after making these changes, and you should now have account support.
