Writing a JIRA User Story with example

We will use this problem statement:
Write business and technical tasks for a web portal and mobie application for "Living Will" for the state of Georgia, USA with using blockchain and we follow JIRA pattern of writing a story.

We will use Gherkin to write user story, in general we write only business purpose story, but it's good to write or add enabler (Technical task) to meet business needs.

Assumption
Portal and app exists

Business User Story

Title: Create Living Will Document
Description: As a user in the state of Georgia, I want to create a Living Will document through the web portal or mobile application, so that I can legally specify my preferences in the event that I am unable to communicate my wishes.
Acceptance Criteria:

Given I am a registered user in Georgia
When I access the web portal or mobile application
Then I should be able to initiate the creation of a Living Will document
And I should be guided through a series of questions to specify my preferences
And I should be able to save and submit the completed Living Will document

Technical Task:

Title: Implement Blockchain Integration for Living Will Documents
