+### Clearing the database read cache
+
+If the database read cache is enabled, **you must run this command** after making any changes to the database outside the application context.
+This includes operations such as restoring a database backup or executing SQL statements like UPDATE, INSERT, DELETE, ALTER, CREATE, or DROP.
+
+Failing to invalidate the cache after such modifications can lead to stale data being served from the cache, and **may cause data corruption** or inconsistent behavior in the application.
+
+Use the following management command to clear the cache:
+
+```
+invalidate_cachalot
+```
+
+!!! info
+The database read cache is based on Django-Cachalot. You can refer to their [documentation](https://django-cachalot.readthedocs.io/en/latest/quickstart.html#manage-py-command).

+## Document Suggestions
+
+Paperless-ngx can suggest tags, correspondents, document types and storage paths for documents based on the content of the document. This is done using a machine learning model that is trained on the documents in your database. The suggestions are shown in the document detail page and can be accepted or rejected by the user.
+
+## AI Features
+
+Paperless-ngx includes several features that use AI to enhance the document management experience. These features are optional and can be enabled or disabled in the settings. If you are using the AI features, you may want to also enable the "LLM index" feature, which supports Retrieval-Augmented Generation (RAG) designed to improve the quality of AI responses. The LLM index feature is not enabled by default and requires additional configuration.
+
+### Document Chat
+
+Paperless-ngx can use an AI LLM model to answer questions about a document or across multiple documents. Again, this feature works best when RAG is enabled. The chat feature is available in the upper app toolbar and will switch between chatting across multiple documents or a single document based on the current view.
+
+### AI-Enhanced Suggestions
+
+If enabled, Paperless-ngx can use an AI LLM model to suggest document titles, dates, tags, correspondents and document types for documents. This feature will always be "opt-in" and does not disable the existing classifier-based suggestion system. Currently, both remote (via the OpenAI API) and local (via Ollama) models are supported, see [configuration](configuration.md#ai) for details.
