Snowplow offers a large number of enrichments that can be used to enhance your event data. Most enrichments attach data to the event as [entities](/docs/fundamentals/entities/), although some enrichments fill or modify event fields directly.

The order of enrichments is hard-coded and can't be changed. The table below lists the available enrichments **in the order they're executed**.

> **Note: Single instance**
>
> You can only configure one instance of each enrichment.
