-## Roadmap
+## Feature Roadmap
  - [x] Model Implementation
  - [x] Pretty Printing
  - [x] Implement visualization utilites for these models in topicwizard
  - [x] Thorough documentation
- - [x] Dynamic modeling (currently `GMM` and `ClusteringTopicModel` others might follow)
+ - [x] Dynamic modeling (`GMM`, `ClusteringTopicModel` and `KeyNMF`)
  - [ ] Publish papers :hourglass_flowing_sand: (in progress..)
  - [ ] High-level topic descriptions with LLMs.
  - [ ] Contextualized evaluation metrics.
 
 
+#### New in version 0.3.0: Dynamic KeyNMF
+KeyNMF can now be used for dynamic topic modeling.
+
+```python
+from datetime import datetime
+from turftopic import KeyNMF
+
+corpus: list[str] = [...]
+timestamps = list[datetime] = [...]
+
+model = KeyNMF(10)
+doc_topic_matrix = model.fit_transform_dynamic(corpus, timestamps=timestamps, bins=10)
+
+model.print_topics_over_time()
+
+# This needs Plotly: pip install plotly
+model.plot_topics_over_time()
+```
