+## Bootstrap 4 Legacy Build Process
+
+Some of our build tasks have been duplicated to support both Bootstrap 4 and Boostrap 5 asset generation. The *default* version of tasks will generate v5 assets.
+
+**CSS Tasks** `npm run css` will generate v5 assets, while `npm run css-bs4` will generate necessary assets for v4.
+
+**JS Tasks** `npm run js` will generate v5 assets, while `npm run js-bs4` will generate necessary assets for v4.
+
+**Watch Tasks** `npm run watch` and `npm run watch-bs` will only generate for v5. Once complete, run `npm run dist` to update v4.
+
+**Dist Task** `npm run dist` will generate both v4 & v5 assets.
+
+**Other Assets** This theme also includes a few additional files directories to support Bootstrap 4 in `/src/build-bootstrap4/`, `/src/sass/assets/bootstrap4/`, and `/src/js/bootstrap4.js`
