 Let's say you want to find ringed galaxies and you have a small labelled dataset of 500 ringed or not-ringed galaxies. You can retrain Zoobot to find rings like so:
 
-    ```python
+```python
+import pandas as pd
+from galaxy_datasets.pytorch.galaxy_datamodule import GalaxyDataModule
+from zoobot.pytorch.training import finetune
 
-    import pandas as pd
-    from galaxy_datasets.pytorch.galaxy_datamodule import GalaxyDataModule
-    from zoobot.pytorch.training import finetune
+# csv with 'ring' column (0 or 1) and 'file_loc' column (path to image)
+labelled_df = pd.read_csv('/your/path/some_labelled_galaxies.csv')
 
-    # csv with 'ring' column (0 or 1) and 'file_loc' column (path to image)
-    labelled_df = pd.read_csv('/your/path/some_labelled_galaxies.csv')
+datamodule = GalaxyDataModule(
+    label_cols=['ring'],
+    catalog=labelled_df,
+    batch_size=32
+)
 
-    datamodule = GalaxyDataModule(
-      label_cols=['ring'],
-      catalog=labelled_df,
-      batch_size=32
-    )
+# load trained Zoobot model
+model = finetune.FinetuneableZoobotClassifier(checkpoint_loc, num_classes=2)  
 
-    # load trained Zoobot model
-    model = finetune.FinetuneableZoobotClassifier(checkpoint_loc, num_classes=2)  
-    
-    # retrain to find rings
-    trainer = finetune.get_trainer(save_dir)
-    trainer.fit(model, datamodule)
-    ```
+# retrain to find rings
+trainer = finetune.get_trainer(save_dir)
+trainer.fit(model, datamodule)
+```
 
 Then you can make predict if new galaxies have rings:
 
-    ```python
-    from zoobot.pytorch.predictions import predict_on_catalog
+```python
+from zoobot.pytorch.predictions import predict_on_catalog
 
-    # csv with 'file_loc' column (path to image). Zoobot will predict the labels.
-    unlabelled_df = pd.read_csv('/your/path/some_unlabelled_galaxies.csv')
+# csv with 'file_loc' column (path to image). Zoobot will predict the labels.
+unlabelled_df = pd.read_csv('/your/path/some_unlabelled_galaxies.csv')
 
-    predict_on_catalog.predict(
-      unlabelled_df,
-      model,
-      label_cols=['ring'],  # only used for 
-      save_loc='/your/path/finetuned_predictions.csv'
-    )
-    ```
+predict_on_catalog.predict(
+    unlabelled_df,
+    model,
+    label_cols=['ring'],  # only used for 
+    save_loc='/your/path/finetuned_predictions.csv'
+)
+```
