+- Update app configuration (located at `OhmGraphite.exe.config`). See configs for [Graphite](#graphite-configuration), [InfluxDB](#influxdb-configuration), [Prometheus](#prometheus-configuration), [Timescale / Postgres](#timescaledb-configuration)
 - This config can be updated in the future, but will require a restart of the app for effect.
 - The app can be ran interactively by executing `.\OhmGraphite.exe run`. Executing as administrator will most likely increase the number of sensors found (OhmGraphite will log how many sensors are found).
 - To install the app `.\OhmGraphite.exe install`. The command will install OhmGraphite as a Windows service (so you can manage it with your favorite powershell commands or `services.msc`)
