+## Capture Modes
+
+MongoDB [change streams](https://www.mongodb.com/docs/manual/changeStreams/) are
+the preferred way to capture on-going changes to collections. Change streams
+allow capturing real-time events representing new documents in your collections,
+updates to existing documents, and deletions of documents. If change streams are
+enabled on the MongoDB instance/deployment you are connecting to, they will be
+used preferentially for capturing changes.
+
+An alternate "batch" mode of capturing documents can be used for deployments
+that do not support change streams, and for MongoDB collection types that do not
+support change streams ([views](https://www.mongodb.com/docs/manual/core/views/)
+and [time
+series](https://www.mongodb.com/docs/manual/core/timeseries-collections/)
+collections). The capture mode is configured on a per-collection level in the
+**Bindings** configuration and can be one of the following:
+- **Change Stream Incremental**: This is the preferred mode and uses change streams to capture change events.
+- **Batch Snapshot**: Performs a "full refresh" by scanning the entire MongoDB
+ collection on a set schedule. A cursor field must be configured, which should
+ usually be the `_id` field.
+- **Batch Incremental**: Performs a scan on a set schedule where only documents
+ having a higher cursor field value than previously observed are captured. This
+ mode should be used for append-only collections, or where a field value is
+ known to be strictly increasing for all document insertions and updates.
+
+:::tip Using Cursor Fields
+For best performance the selected cursor field should have an
+[index](https://www.mongodb.com/docs/manual/indexes/). This ensures backfill
+queries are able to be run efficiently, since they require sorting the
+collection based on the cursor field.
+:::
+
+:::tip Time Series Collections
+Time series collections do _not_ have a default index on the `_id`, but do have
+an index on the `timeField` for the collection. This makes the `timeField` a
+good choice for an incremental cursor if new documents are only ever added to
+the collection with strictly increasing values for the `timeField`. The capture
+connector will automatically discover time series collections in **Batch
+Incremental** mode with the cursor set to the collection's `timeField`.
+:::
+
+Only the **Change Stream Incremental** mode is capable of capturing deletion
+events. **Batch Snapshot** will capture updates by virtue of it re-capturing the
+entire source collection periodically. **Batch Incremental** _may_ capture
+updates to documents if updated documents have strictly increasing values for
+the cursor field.
