+
 ```
 yarn solink testToken --amount 10000000000
 ```

-Please refer to the integration-example
+Refer to the [integration-example][./integration-example].
+
+The gist is to pass in the feed address to the program, and call `get_median` from the flux_aggregator crate.
+
+```rust
+use flux_aggregator;
+
+let feed_info = next_account_info(accounts_iter)?;
+let value = flux_aggregator::get_median(feed_info)?;
+```
