 ## Using BioImage Model Zoo models in different software
 
 ### BiaPy
-TBD
+**Note: BiaPy empowers users to train custom models or fine-tune existing ones for bioimaging tasks and upload them to the BioImage Model Zoo. BiaPy supports models exported with PyTorch.**
+
+BiaPy adapts to users of all expertise levels, offering multiple ways to run and interact with models:
+- Graphical User Interface (GUI): Ideal for beginners.
+- No-Coding Jupyter Notebooks: Simplified workflows for those without programming knowledge.
+- Docker Containers: Ensure reproducibility and isolation.
+- Command Line Interface (CLI): Perfect for advanced users.
+
+How you interact with BioImage Model Zoo models also depends on your chosen method. Get started with the resources below:
