# line breaks are normal \n 

Ok, here we go with the [b]sample[/b] that needs to be [b][i]parsed[/i][/b] into proper JSON format.
We can have multiple lines inside a paragraph, with [url=http://example.com]links[/url] to different [b][url=http://manager.example.com]websites[/url][/b].

This is another paragraph with an inline image. [img]http://via.placeholder.com/280x140/[/img]

[img]http://via.placeholder.com/200x140/[/img] can be in the beginning of the parapraph. It can also be inside of a link:
[url=http://image.example.com][img]http://via.placeholder.com/280x100/[/img][/url] so it's tricky.

[list]
[*] here is an unordered list
[*] with [b]various[/b] line items
[*] can be a link [url=http://example.com]here as well[/url]
[/list]

[align=center] This is a centered paragraph. Nothing interesting here. [/align]
