+# Debugging nvf {#sec-debugging-nvf}
+
+There may be instances where the your Nix configuration evaluates to invalid
+Lua, or times when you will be asked to provide your built Lua configuration for
+easier debugging by nvf maintainers. nvf provides two helpful utilities out of
+the box.
+
+**nvf-print-config** and **nvf-print-config-path** will be bundled with nvf as
+lightweight utilities to help you view or share your built configuration when
+necessary.
+
+To view your configuration with syntax highlighting, you may use the
+[bat pager](https://github.com/sharkdp/bat).
+
+```bash
+nvf-print-config | bat --language=lua
+```
+
+Alternatively, `cat` or `less` may also be used.
