How to implement a Tensorflow CNN model for Image Classification?

model=tf.keras.Sequential([
      tf.keras.layers.Conv2D(32,(3,3),activation='relu',input_shape=(32,32,3)),
      tf.keras.layers.MaxPool2D((2,2)),
      tf.keras.layers.Conv2D(64,(3,3),activation='relu'),
      tf.keras.layers.MaxPool2D((2,2)),
      tf.keras.layers.Conv2D(64, (3, 3), activation='relu'),
      tf.keras.layers.Flatten(),
      tf.keras.layers.Dense(64,activation='relu'),
      tf.keras.layers.Dense(100)

])
