 ## Supported languages and themes
-To add new languages/color themes to delta, the process is
+To list the supported languages and color themes, use `delta --list-languages` and `delta --list-theme-names`. To see a demo of the color themes, use `delta --list-themes`.
 
-1. Clone the delta repo
-2. Create new versions of the files `assets/syntaxes.bin` and/or `assets/themes.bin`. Please see the [bat](https://github.com/sharkdp/bat#adding-new-syntaxes--language-definitions) documentation for instructions on how to create new versions of these files. You will need to copy them into the `assets/` directory of the delta git repo after creating them.
-3. Recompile delta: `cargo build --release`
-4. Now you have a new delta executable at `target/release/delta` that should feature your new language/theme (use `--list-languages` / `--list-themes` to check).
+delta uses the same mechanisms as [bat](https://github.com/sharkdp/bat#adding-new-syntaxes--language-definitions) for locally adding custom color themes and support for new languages: please see the [bat](https://github.com/sharkdp/bat#adding-new-syntaxes--language-definitions) documentation. You will need to install bat in order to run the `bat cache --build` command.
 
-Delta does not currently support reading these files dynamically from `~/.config` as `bat` does, but this is a feature that could be added.
+The languages and color themes that ship with delta are those that ship with bat. So, to propose a new language or color theme for inclusion in delta, it would need to be a helpful addition to bat, in which case please open a PR against bat.
