# Viewing and editing documentation
## Viewing documentation
To view documentation, simply navigate to a model within your project. The extension pane will automatically change to show the relevant model and column descriptions.
On startup, you may see a loading screen for a few seconds. Our extension needs both the `catalog.json` and `manifest.json` to work, so it needs to create these files by instructing your machine to run dbt commands.
## Editing documentation
To edit documentation, make changes to the model and column description fields in the extension pane, and then press `Save`. Your updates will be automatically saved to the correct YAML file, or a new one will be created if necessary. After saving, you will see a notification in the bottom right of your screen indicating that the changes have been applied and allowing you to view them. Click the `View Changes` button to open a diff view of the updated YAML file.
If you edit a model, you must materialize your changes (i.e. run `dbt run`) and then press the **↻** button at the top of the extension to update your columns.
