+
+If you are using a Requests project instead of a Scrapy project, you can link it to Estela by following these steps:
+
+1. Ensure you have created a Requests project using Estela Requests. Refer to the [Estela Requests documentation](https://github.com/bitmakerla/estela-requests/tree/main#basic-usage) for instructions on creating a project.
