Convert TXT JIRA to MARKDOWN

The Jira/Confluence Wiki Markup, often stored with a TXT file extension, referred to as Wiki Markup, is used in Atlassian's Jira and Confluence applications for creating and formatting content. It allows users to write text in a simplified markup language, which is then converted into rich text. This format is particularly useful for documentation, linking to specific parts of pages, and embedding macros. Wiki Markup has been a part of Confluence since its early versions, enabling users to easily manage and organize information.

Markdown is a lightweight markup language with a plain text formatting syntax, primarily used in Markdown documentation files with the MD extension. Created by John Gruber and Aaron Swartz in 2004, it allows IT professionals to easily format text for web pages, readme files, and technical documentation. Markdown's simplicity and readability make it ideal for collaborative projects and version control systems. Its syntax is designed to be readable without compromising the document's formatting when rendered as HTML or other web formats.
