# Configuring Transforms.xml and creating/installing STS

This section explains how to configure the `Transforms.xml` file and create and install STS.

Note: If an error occurs, check the log file.

1. In the Transforms.xml file located in Admin-InstallTransformKit, change all server names to the desired server name or URL.
2. In the Transforms.xml file, add the following line after `STS.UseDevEnvSettings`:
   - `STS.TokenSigningCertThumbprint`; insert the thumbprint value available from the Details tab for your certificate. Remove the spaces from the value and verify no hidden characters appear.
3. Change the database name in the connection string if not using the default.
4. In the `InitialTransformKit-Osprey` file, change `MsiTransform.exe-rename` to `MsiTransform.exe`.

   Note: The OspreyInstaller_AdminSTS.msi installation file is located in InstallTransformKit-Osprey/Installs/ folder.
