+## Saving and Loading Models
+
+If you wish to save a particular model and use it elsewhere or at a later point in time, darts can achieve that. It leverages pickle and in the case of Torch models relies on saving PyTorch Lightning trainer checkpoints.
+All forecasting models support saving the model on the filesystem, by calling the `save()` function, which saves that particular `ForecastingModel` object instance. When the model is to be used again, the method `load()` can be used. Please note that the methods `save_model()` and `load_model()` are deprecated.
+
+**Example:**
+```python
+from darts.models import RegressionModel
+
+model = RegressionModel(lags=4)
+
+model.save("my_model.pkl")
+model_loaded = RegressionModel.load("my_model.pkl")
+```
+
+The parameter `path` specifies a path or file handle under which to save the model at its current state. If no `path` is specified, the model is automatically
+saved under ``"{ModelClass}_{YYYY-mm-dd_HH:MM:SS}.pkl"``. E.g., ``"RegressionModel_2020-01-01_12:00:00.pkl"``.
+Optionally there is also pickle specific keyword arguments `protocol`, `fix_imports` and `buffer_callback`.
+More info: [pickle.dump()](https://docs.python.org/3/library/pickle.html?highlight=dump#pickle.dump)
+
+With torch models, the model parameters and the training state are saved. We use the trainer to save the model checkpoint.
+
+**Example:**
+```python
+from darts.models import NBEATSModel
+
+model = NBEATSModel(input_chunk_length=24,
+                    output_chunk_length=12)
+
+model.save("my_model.pt")
+model_loaded = NBEATSModel.load("my_model.pt")
+```
+
+Private methods for torch models used under the hood:
+
+* **save_checkpoint:** In addition, we need to use PTL save_checkpoint() to properly save the trainer and model. It is used to be able to save a snapshot of the model mid-training, and then be able to retrieve the model later.
+* **load_from_checkpoint:** returns a model checkpointed during training (by default the one with lowest validation loss).
