+## CLI
+
+The CLI supports the following commands:
+
+```
+python -m observatoire.tmdb.movies --mode=[latest | missing]
+python -m observatoire.tmdb.series --mode=[latest | missing]
+```
+
+In the `latest` mode, which is the default, these commands sync the latest records from TMDB to our datasets on Hugging Face.  In the `missing` mode, they calculate which rows may be missing from the Hugging Face datasets and attempt to sync these records.
