 # Setting up the Back-End Drupal Application
 
-TODO
+The Drupal back-end for my Blue Conf 2019 talk - [Decoupling Drupal with Vue.js](https://www.oliverdavies.uk/talks/decoupling-drupal-vuejs). This was used alongside the Vue.js front-end application for viewing and submitting fictional talk proposals that were stored in Drupal.
+
+## Prerequisites
+
+* [Docksal](https://docksal.io)
+* [VirtualBox](https://www.virtualbox.org/wiki/Downloads) (can be changed to use Docker natively)
+
+## Setup instructions
+
+1. Run `fin init` to initialise the project, including installing all of the Composer dependencies, installing Drupal and importing the original configuration and creating some test content.
+
+    ```bash
+    cd drupal
+
+    fin init
+    ```
+
+1. Visit `http://blueconf.docksal` to view the Drupal website, or run `fin drush status` to ensure that everything is running.
+
+1. Run `fin drush uli` to generate a one-time login link in order to access the site.

 # Setting up the Front-End Vue.js Application
- TODO
+
+The Vue.js front-end for my Blue Conf 2019 talk - [Decoupling Drupal with Vue.js](https://www.oliverdavies.uk/talks/decoupling-drupal-vuejs). It is a [Vue CLI](https://cli.vuejs.org) application, and uses [Tailwind CSS](https://tailwindcss.com) for styling.
+
+## Prerequisites
+
+* [npm](https://docs.npmjs.com/cli/npm)
+* [yarn](https://yarnpkg.com) (optional)
+
+## Setup instructions
+
+1. Install the npm dependencies using either `npm` or `yarn`.
+
+    ```bash
+    cd vuejs
+
+    # Using npm
+    npm install
+
+    # Using yarn
+    yarn
+    ```
+
+1. Change the URL to the Drupal back-end if needed in `.env`.
+
+1. Use `yarn serve` to start a local web server.
+
+1. Visit the URL (usually `http://localhost:8080`) to view the front-end application.
