+
+### Format with Prettier
+
+Run the following command to format files with Prettier:
+
+```shell
+docker compose run node prettier --write src/
+```
+
+```shell
+## Or alternatively, if docker compose run is slow to run
+docker compose up --detach
+docker compose exec node prettier --write src/
+docker compose down
+```
+
 ## Structure
 
 The initial markup is rendered via the `index.html` file. Visual display is derived from the `style.css` rules. Styles extend from `src/vocabulary`.
 
-On initlialization the `scripts.js` functions set the correct fieldsets to default display; based on user provided actions through the stepper fieldsets will display or hide, exposing the relevant pathways to getting a `tool` recommendation. Correct pathways are located within the `rawStatePathRoutes` array. When a correct pathway matches the current `state`, the appropriate `tool` is matched and recommended, if the current state is not a known pathway the `tool` is set to `unknown` until the required input is given.

 The main `tool` recommendation content is pulled via the appropriate `<template>` markup located within HTML. Additional information for the marking formats is also sourced from these `<template>` elements and the contents of the `Attribution Details` fields.
