     # Making a Hate Speech Detection Model
 
-    This is where design choices will go.
+    Once the data has been collected using the definitions identified for the 
+    task, you can start training your model. At training, the model takes in 
+    the data with labels and learns the associated context in the input data 
+    for each label. Depending on the task design, the labels may be binary like 
+    'hateful' and 'non-hateful' or multiclass like 'neutral', 'offensive', and 
+    'attack'. 
+    
+    When presented with a new input string, the model then predicts the 
+    likelihood that the input is classified as each of the available labels and
+    returns the label with the highest likelihood as well as how confident the 
+    model is in its selection using a score from 0 to 1. 
+    
+    Neural models such as transformers are frequently trained as general 
+    language models and then fine-tuned on specific classification tasks.
+    These models can vary in their architecture and the optimization 
+    algorithms, sometimes resulting in very different output for the same 
+    input text.
