 If required, modify the file under `grobid/grobid-home/config/grobid.yaml` for starting the server on a different port or if you need to change the absolute path to your `grobid-home` (e.g. when running on production). By default `grobid-home` is located under `grobid/grobid-home`. `grobid-home` contains all the models and static resources required to run GROBID.
 
+See the [configuration page](Configuration.md) for details on how to set the different parameters of the `grobid.yaml` configuration file. Service and logging parameters are also set in this configuration file.

 ### Model loading strategy 
 You can choose to load all the models at the start of the service or lazily when a model is used the first time, the latter being the default.
