+## Checkpoints
+
+We provide two model checkpoints that you can use directly with nnU-Net:
+
+- **mixed_model_continual_learning.zip**  
+
+- **pure_pediatric_model.zip**  
+
+### Installing Pretrained Models
+
+nnU-Net offers a convenient utility to install pretrained models from a zip archive. Follow these steps:
+
+1. **Downloading Pretrained Weights:**  
+   Go to the [GitHub Releases](https://github.com/ICANS-Strasbourg/PSAT/releases) page.
+  
+   Download:
+   - `mixed_model_continual_learning.zip`
+   - `pure_pediatric_model.zip`
+ 
+   Place them in `resources/checkpoints/`.
+
+2. **Install the Checkpoint Using nnU-Net**  
+   Use the `nnUNet_install_pretrained_model_from_zip` command in your terminal.
+
+   ```bash
+   # To install the mixed model checkpoint:
+   nnUNetv2_install_pretrained_model_from_zip resources/checkpoints/mixed_model_continual_learning.zip
+
+   # To install the pure pediatric model checkpoint:
+   nnUNetv2_install_pretrained_model_from_zip resources/checkpoints/pure_pediatric_model.zip
+
+3. **Running Inference**
+
+    Once you have installed a checkpoint, you can run inference on your input images using the `nnUNet_predict` command.
