+### What's the difference between core and verified sources?
+
+The main difference between the [core sources](#core-sources) and [verified sources](#verified-sources) lies in their structure.
+Core sources are generic collections, meaning they can connect to a variety of systems. For example, the [SQL Database source](sql_database) can connect to any
+database which supports SQLAlchemy.
+
+According to our telemetry, core sources are the most widely used among our users!
+
+It's also important to note that core sources are integrated into the `dlt` core library,
+whereas verified sources are maintained in a separate [repository](https://github.com/dlt-hub/verified-sources).
+To use a verified source, you need to run the `dlt` init command, which will download the verified source code to
+your working directory.
