+## Token Defaults Generator
+
+Script that generates component theme data defaults based on token data.
+
+## Usage
+Run this program from the root of the git repository:
+```sh
+dart packages/material_ui/tool/m3e_gen_defaults/bin/gen_defaults.dart [-v]
+```
+
+This updates generated component theming files under
+`packages/material_ui/lib/src/m3e/generated`.
+
+## Templates
+
+There is a template file for every component that needs defaults from the token
+database. These templates are implemented as subclasses of `TokenTemplate`.
+
+Templates need to override the `generateContents` method to provide the
+generated code block as a string.
+
+## Tokens
+
+Tokens are stored in `data/`, and are sourced from an internal Google database.
