How to set Vim as a manpager?
** Back
~MANPAGER="nvim +Man!"~

~+Man!~ is a command invocation (as if entering ~:Man~ inside Vim).
It can also be written as ~-c Man!~.

The ~:Man!~ command displays the current buffer as a manual page.

=gO=, although the results are filetype-specific (and some don't have any).
Helpful examples include for manual pages and help pages (from =:help=).

:END:
** Front
How does Vim detect the files?
** Back
Vim guesses the file by assigning *filetypes*, mainly through the file name and reading the file content.
A filetype is how Vim knows what plugins to apply to the current buffer.

Vim has a few built-in filetypes such as shell, manual pages, Markdown, Asciidoc, xmodmap, patch files, and JSON among others (that are in =$VIMRUNTIME/filetype.vim=).

For more information, run ~:help filetype~ inside Vim.
