Typical skeleton for a TecDoc XML config:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <connectionStrings>
    <add name="TecDocDB"

  </connectionStrings>
  <appSettings>
    <add key="LicenseKey" value="XXXX-XXXX-XXXX-XXXX" />
    <add key="DataPath" value="C:\TecDocData" />
    <add key="UpdateUrl" value="https://update.tecalliance.net/tecdoc/v5/" />
  </appSettings>
</configuration>

This file contains the "map" your software uses to find, authenticate with, and parse the Tecdoc database. Crucial: Never guess the connection string format
