+Vendor Snippets
+---------------
+
+Additional library and framework snippets are available for UltiSnips users in
+the `UltiSnips/` directory. These files are removed from the default language
+namespaces to prevent them from all being loaded automatically. If there is a
+separate library, framework, or package you would like to support open a pull
+request!
+
+Additional snippets can be added to the current buffer with the
+`:UltiSnipsAddFiletypes` command followed by the snippet name without the
+"snippets" ending. For example, to add the JavaScript Jasmine snippets, run:
+`:UltiSnipsAddFiletypes javascript-jasmine`. To have this snippet loaded
+everytime a JavaScript file is opened or created you can add the command to your
+`.vim/ftplugin/javascript.vim` file.
+
+For more see the UltiSnips docs (`:help UltiSnips`).
