Detailed example

Suppose we have a Trello board called projects with lists Brainstorm, TODO, DOING, DONE. Lists contains own cards.
All Trello boards have its own id this id requires Trellodon to fetch board via Trello API. You can find this id in two ways:

• In URL https://trello.com/b/{id}/projects your Trello board id will be placed as {id} in example;
• Put .json in your board URL like this https://trello.com/b/{id}/projects.json id field in json output is what you need;

You can also paste whole board URL and Trellodon will parse it correctly.
After launch Trellodon creates follow output in specified folder:

projects/
  Brainstorm/
    first_card_title/
       README.md
       attachments/
         image.png
  TODO/
    first_card_title/
       README.md
       attachments/
         report.docx
  ...

Each card has follow output format:

---
title: card_title
last_updated_at: 2022-03-16 16:28:39 UTC
labels: Test
---
