Indentation

Full references: Indentation
To indent a paragraph prefix all of its lines with at least 2 spaces. To indent more, increase that number. Depending on the template different indentation levels might be displayed differently – for example, in our case they’re colored in dark blue.

First-level indentation.
The second line of the same paragraph
which is also indented.

Another paragraph, this time
more indented than previous.

Back to first level indentation.
Line breaks work here, as well as other wiki markup does.

Note that only clearly different paragraphs are indented (the fewest leading whitespace is counted):

This is an indented text.
This is the same paragraph
and thus indentation is the same.
Once again, the same paragraph.

This paragraph is fine, though,

because it's split in between

…so actually there are two paragraphs.
