-# Building Assets
+# Local Development
+Pterodactyl is now powered by Vuejs and Tailwindcss and uses webpack at its core to generate compiled assets. Release
+versions of Pterodactyl will include pre-compiled, minified, and hashed assets ready-to-go.
 
-```
+However, if you are interested in running custom themes or making modifications to the Vue files you'll need a build
+system in place to generate these compiled assets. To get your environment setup, you'll first need to install at least Nodejs
+`8`, and it is _highly_ recommended that you also install [Yarn](https://yarnpkg.com) to manage your `node_modules`.
+
+### Install Dependencies
+```bash
 yarn install
-
-yarn run build
 ```
+
+The command above will download all of the dependencies necessary to get Pterodactyl assets building. After that, its as
+simple as running the command below to generate assets while you're developing.
+
+```bash
+# build the compiled assets for development
+yarn run build
+
+# build the assets automatically when files are modified
+yarn run watch
+```
+
+
+### Hot Module Reloading
+For more advanced users, we also support 'Hot Module Reloading', allowing you to quickly see changes you're making
+to the Vue template files without having to reload the page you're on. To Get started with this, you just need
+to run the command below.
+
+```bash
+PUBLIC_PATH=http://192.168.1.1:8080 yarn run serve --host 192.168.1.1
+```
+
+There are two _very important_ parts of this command to take note of and change for your specific environment. The first
+is the `--host` flag, which is required and should point to the machine where the `webpack-serve` server will be running.
+The second is the `PUBLIC_PATH` environment variable which is the URL pointing to the HMR server and is appended to all of
+the asset URLs used in Pterodactyl.
+
+### Building for Production
+Once you have your files squared away and ready for the live server, you'll be needing to generate compiled, minified, and
+hashed assets to push live. To do so, run the command below:
+
+```bash
+yarn run build:production
+```
+
+This will generate a production ready `bundle.js` and `bundle.css` as well as a `manifest.json` and store them in
+the `/public/assets` directory where they can then be access by clients, and read by the Panel.
