 # next-pre-css
-Adds support for both Stylus & Less CSS preprocessing in NextJS
+Adds support for both Stylus & Less CSS pre-processing in NextJS v10+.
+
+## Step 1 - Install next-pre-css & Your Choice of Flavor
+
+### for Stylus?
+Install both Stylus and the Stylus loader for Webpack:
+```
+$ npm i -D stylus stylus-loader next-pre-css
+```
+
+### for Less?
+Install both Less and the Less loader for Webpack:
+```
+$ npm i -D less less-loader next-pre-css
+```
+
+## Step 2 - Setup your NextJS Config
+If you don't already have a [NextJS Config](https://nextjs.org/docs/api-reference/next.config.js/introduction), create one.
+```
+touch next.config.js
+```
+In the config, `require()` the next-pre-css module and wrap your config with it as follows.
+```
+const addSupport = require('next-pre-css')
+
+module.exports = addSupport({
+  webpack: (config, options) => {
+	
+    /* ...and the rest of your custom webpack config goes here. */
+		
+    return config;
+  },
+})
+```
+As an extra example; adding GraphQL and the GraphQL-Tag loader (because why not?):
+```
+const addSupport = require('next-pre-css')
+
+module.exports = addSupport({
+  webpack: (config, options) => {
+    config.module.rules.push({
+      test: /\.(graphql|gql)$/,
+      exclude: /node_modules/,
+      loader: 'graphql-tag/loader',
+    })
+    return config
+  },
+  webpackDevMiddleware: (config) => {
+    return config
+  },
+})
+```
+
+## Step 3 - Um... Do Your Thing.
+Begin working w/ the same pleasentries that NextJS provides Sass with (such as [component-level styling](https://nextjs.org/docs/basic-features/built-in-css-support#adding-component-level-css) like: `mah-css.module.styl` or `mah-css.module.less`, but for the pre-processor that _you_ prefer. Under-the-hood, this module does little more than modify the webpack rules NextJS sets for Sass & CSS to include both Stylus and Less. So that's it. 
+
+Hence forth, Go Nuts!
