+var stringContent = `Generate a Pre-Signed URL for an Amazon S3 PUT Operation with a Specific Payload
+You can generate a pre-signed URL for a PUT operation that checks whether users upload the correct content. When the SDK pre-signs a request, it computes the checksum of the request body and generates an MD5 checksum that is included in the pre-signed URL. Users must upload the same content that produces the same MD5 checksum generated by the SDK; otherwise, the operation fails. This is not the Content-MD5, but the signature. To enforce Content-MD5, simply add the header to the request.
+
+The following example adds a Body field to generate a pre-signed PUT operation that requires a specific payload to be uploaded by users.
