+### 2.1\. Requirements
+
+Syntastic itself has rather relaxed requirements: it doesn't have any external
+dependencies, and it needs a version of [Vim][13] compiled with a few common
+features: `autocmd`, `eval`, `file_in_path`, `modify_fname`, `quickfix`,
+`reltime`, and `user_commands`. Not all possible combinations of features that
+include the ones above make equal sense on all operating systems, but Vim
+version 7 or later with the "normal", "big", or "huge" feature sets should be
+fine.
+
+Syntastic should work with any modern plugin managers for Vim, such as
+[NeoBundle][14], [Pathogen][1], [Vim-Addon-Manager][15], [Vim-Plug][16], or
+[Vundle][17]. Instructions for installing syntastic with [Pathogen][1] are
+included below for completeness.
+
+Last but not least: syntastic doesn't know how to do any syntax checks by
+itself. In order to get meaningful results you need to install external
+checkers corresponding to the types of files you use. Please consult the
+[wiki][3] for a list of supported checkers.
