+### Design Workflow
+
+To design and create your indexer, you can follow this recommended workflow:
+
+1. Using [nearblocks.io](https://nearblocks.io), find transactions to smart contracts that you want to index
+2. Take the block `height` and put it into the [Debug Mode filter](../queryapi/index-function.md#local-debug-mode), open your browser's _Developer Console_, and hit <kbd>Play</kbd>
+4. Inspect the block and write JavaScript code using [NEAR Lake Primitives](../../2.develop/lake/lake-primitives.md) to extract data from a `block` object. (This JS code will be your [`IndexingLogic.js`](#indexinglogicjs))
+   > **Tip:** Use `context.log` for debugging to ensure you are getting the right results
+4. Add more blocks for debugging, or start following the blockchain to see how new blocks are handled
+5. Create tables that you need to store the data using Postgres [CREATE table syntax](https://www.postgresql.org/docs/current/sql-createtable.html). (This SQL code will be your [`schema.sql`](#schemasql))
