 ## Overview
+BERTopic has quite a number of functions that quickly can become overwhelming. To alleviate this issue, you will find an overview 
+of all methods and a short description of its purpose.

+### Common

+### Variations
+There are many different use cases in which topic modeling can be used. As such, a number of 
+variations of BERTopic have been developed such that one package can be used across across many use cases:
+
+| Method | Code  | 
+|-----------------------|---|
+| (semi-) Supervised Topic Modeling | `.fit(docs, y=y)` |
+| Topic Modeling per Class | `.topics_per_class(docs, topics, classes)` |
+| Dynamic Topic Modeling | `.topics_over_time(docs, topics, timestamps)` |
+| Hierarchical Topic Modeling | `.hierarchical_topics(docs, topics)` |
+| Guided Topic Modeling | `BERTopic(seed_topic_list=seed_topic_list)` |
+
+### Visualizations
+Evaluating topic models can be rather difficult due to the somewhat subjective nature of evaluation. 
+Visualizing different aspects of the topic model helps in understanding the model and makes it easier 
+to tweak the model to your liking.
