 Individual pre-compiled binaries are not currently provided. To compile, the .NET 6.0 SDK needs to be installed. After that, simply running `dotnet publish` should be enough to perform a basic compilation.

 The `appsettings.json` file has default settings for SAMA. They should be modified to fit your needs by creating a copy of the file and naming it `appsettings.Production.json`. Modifications should go into that file.
 
+The `DefaultHttpVersion` setting, available via the app settings files and overridable via environment variables, controls how the .NET HTTP client accesses HTTP(S) endpoints. By default, it uses HTTP 1.1 with a fallback to HTTP 1.0. In some unusual circumstances, you may need to change that behavior. This setting allows such changes. The following values are supported (on most platforms):
+
+- `10_Exact`
+- `10_OrHigher`
+- `11_OrLower` (default)
+- `11_Exact`
+- `11_OrHigher`
+- `20_OrLower`
+- `20_Exact`
+- `20_OrHigher`
+- `30_OrLower`
+- `30_Exact`
+- `30_OrHigher`
