This question type is used in cases where the responder needs to sign a document.
Instead of a signature, if you would like the responder to check a confirmation box, use confirm type instead.

In order to store a signature, you need to set up a S3 bucket or GCS bucket to specify where the file will be stored. For detailed instructions on setting up a file integration in Formsort, you can go to this page for S3 and this page for GCS.
