-You can also use other S3 providers by providing a custom endpoint:
-
-```.env
-S3_UPLOAD_ENDPOINT=http://localhost:9000
-```
-
-### Create expense from receipt
-
-You can offer users to create expense by uploading a receipt. This feature relies on [OpenAI GPT-4 with Vision](https://platform.openai.com/docs/guides/vision) and a public S3 storage endpoint.
-
-To enable the feature:
-
- You must enable expense documents feature as well (see section above). That might change in the future, but for now we need to store images to make receipt scanning work.
- Subscribe to OpenAI API and get access to GPT 4 with Vision (you might need to buy credits in advance).
- Update your environment variables with appropriate values:
-
-```.env
-NEXT_PUBLIC_ENABLE_RECEIPT_EXTRACT=true
-OPENAI_API_KEY=XXXXXXXXXXXXXXXXXXXXXXXXXXXX
-```
-
-### Deduce category from title
-
-You can offer users to automatically deduce the expense category from the title. Since this feature relies on a OpenAI subscription, follow the signup instructions above and configure the following environment variables:
-
-```.env
-NEXT_PUBLIC_ENABLE_CATEGORY_EXTRACT=true
-OPENAI_API_KEY=XXXXXXXXXXXXXXXXXXXXXXXXXXXX
