 Currently, Python Workers using packages cannot be deployed and will only work in local development for the time being.
 
 ### How to Run
+
 Download this quotes file from [Hugging Face in SQL form](https://huggingface.co/datasets/lizziepika/quotes_sql/blob/main/data.sql)
 
 Create a new D1 database by running on the command line `npx wrangler d1 create {D1-NAME}`. Copy and paste the output into your `wrangler.toml` to bind your D1 database to your Python Worker.
 
+Ingest the SQL file you've downloaded by running:
+
+```
+npx wrangler d1 execute {D1-NAME} --local --file=./data.sql
+```
+
 Ensure that your Wrangler version is up to date (3.30.0 and above).
 
 ```
 $ wrangler -v
  ⛅️ wrangler 3.30.0
- ```
-Now, if you run `wrangler dev` within this directory, it should use the config in`wrangler.toml` to run the demo.
