+
+## Opt-in features
+
+### Expense documents
+
+Spliit offers users to upload images (to an AWS S3 bucket) and attach them to expenses. To enable this feature:
+
+- Follow the instructions in the _S3 bucket_ and _IAM user_ sections of [next-s3-upload](https://next-s3-upload.codingvalue.com/setup#s3-bucket) to create and set up an S3 bucket where images will be stored.
+- Update your environments variables with appropriate values:
+
+```.env
+NEXT_PUBLIC_ENABLE_EXPENSE_DOCUMENTS=true
+S3_UPLOAD_KEY=AAAAAAAAAAAAAAAAAAAA
+S3_UPLOAD_SECRET=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
+S3_UPLOAD_BUCKET=name-of-s3-bucket
+S3_UPLOAD_REGION=us-east-1
+```
+
+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
+```
