+This demo shows an example of using CSV enrichment in Vector to enrich events with data from two CSV files.
 
-The CSV file ([`./data/users.csv`](./data/users.csv) contains a list of users with their phone numbers and addresses.
+The [`users.csv`](./data/users.csv) file contains a list of users with their phone numbers and addresses, while the

+The [`vector.toml`](./vector.toml) configuration contains:
 
-* A `random` source in the `vector.toml` that simply generates some fake events using names that match users in the CSV file
-* A `remap` transform then parses these events and then looks up the corresponding record from the CSV file to enrich the event with more metadata
+* Two `generator` sources in the that generate fake events that can be enriched using the CSV files (user data and coded error messages

+* Two `remap` transforms that parse the events and then look up the corresponding records from the CSV files to enrich the events with more metadata
 * A `console` sink to print out the events
