+# Nimf Vim Syntax
+
+A syntax and indentation setup for nimf, an interpreted stack based language (really, a naive attempt at a forth-like language).
+
+## What it does
+
+The syntax highlights many common 'words' and builtins. It also does a reasonably sane autoindent and sets widths for the indent.
+
+## License

+BSD 2-clause
