        ## Markdown editor

        You can create your target text content using this editor. Use the preview button to get a feel of the generated content. Here is a basic guide to format content using markdown:

        ## Headings

        # This is a Level 1 heading
        ### This is a Level 3 heading
        ###### This is a Level 6 heading

        ## Emphasis

        *This text will be italic.*

        _This will also be italic._

        **This text will be bold.**

        __This will also be bold.__
