Config file to train RTMDet on custom dataset with 2 classes

[AndreaPi]

As per object, I would like to have a config file for training RTMDet on a custom dataset with only 2 classes. In the documentation there's only one example of training a model on a custom dataset:

https://mmdetection.readthedocs.io/en/latest/user_guides/train.html#train-with-customized-datasets

but that model is Mask-RCNN, not RTMDet. Can you point to such a config file, or at least tell me what I should change? I'm using the rtmdet_s_8xb32-300e_coco.py config file
