+
+This project now includes a new class `MNISTTrainer` which is used to train a model on the MNIST dataset.
+
+## MNISTTrainer
+
+The `MNISTTrainer` class is defined in `src/main.py`. It includes methods for loading and preprocessing the MNIST dataset, defining the model architecture, and training the model.
+
+### Usage
+
+An instance of `MNISTTrainer` is created and then its methods are used to load the data, define the model, and train the model. Here is an example:
+
+```python
+# Create an instance of MNISTTrainer
+trainer = MNISTTrainer()
+
+# Load the data
+trainloader = trainer.load_data()
+
+# Define the model
+Net = trainer.define_model()
+model = Net(trainloader)
+
+# Train the model
+optimizer = optim.SGD(model.parameters(), lr=0.01)
+criterion = nn.NLLLoss()
+
+# Training loop
+epochs = 3
+for epoch in range(epochs):
+    for images, labels in model.trainloader:
+        optimizer.zero_grad()
+        output = model(images)
+        loss = criterion(output, labels)
+        loss.backward()
+        optimizer.step()
+```
+
+The trained model is then saved and can be loaded in `src/api.py` using the `MNISTTrainer` class in a similar way:
+
+```python
+# Create an instance of MNISTTrainer
+trainer = MNISTTrainer()
+
+# Load the data
+trainloader = trainer.load_data()
+
+# Define the model
+Net = trainer.define_model()
+model = Net(trainloader)
+
+# Load the model's state from the saved file
+model.load_state_dict(torch.load("mnist_model.pth"))
+model.eval()
+```
