 ## Installation
 
- 1. I think this project requires PHP 7.3 or later, so be sure that your system complies.
- 1. Sign up at https://stackapps.com/apps/oauth/register to receive a Client ID, Client Secret, and Key. (It's free, easy, and fast.)
- 1. Create a Laravel project, and make sure that it works: https://laravel.com/docs/5.8/installation#installing-laravel
- 1. Add this package into your Laravel project: `vagrant@vboxHomestead:~/Code/MyLaravelProject$ composer require ryancwalsh/stack-exchange-backup-laravel:dev-master --prefer-source`
- 1. Run `php artisan vendor:publish`, and if it gives you a choice, choose to publish from this package.
- 1. Edit your Laravel project's `.env` file to have your own StackApps values. A non-working sample is below.
- 1. Run `php artisan exportStackExchange`. (Note that `php artisan exportStackExchange --flushCache` is an available option to clear the cached access code value.)
- 1. Following the instructions in the terminal, you'll use your browser to visit a URL that will provide you with a temporary access token to paste into the terminal.
- 1. Finished! The JSON files will appear in your `/storage/app/StackExchange` folder.
+There is no need to clone this repository, the installation works with _PHP
+composer_. It will install the _Laravel_ framework and add this project to the
+app.
+
+ 1. This is only tested on PHP 7.3, so be sure that your system complies.
+
+ 1. Sign up at https://stackapps.com/apps/oauth/register to receive a Client
+    ID, Client Secret, and Key (it's free, easy, and fast). Note: use 
+    `stackexchange.com` for `OAuth Domain` in the setup.
+
+ 1. Create a [Laravel project](https://laravel.com/docs/5.8/installation#installing-laravel)
+    for this app, and make sure that it works:
+        
+        mkdir ~/Code/Laravel
+        cd ~/Code/Laravel
+        composer global require laravel/installer
+        # on Ubuntu 18.04 and Debian 9+:
+        echo 'export PATH="$PATH:$HOME/.config/composer/vendor/bin"' >> ~/.bashrc
+        # on other systems this might be
+        # echo 'export PATH="$PATH:$HOME/.composer/vendor/bin"' >> ~/.bashrc
+        # apply PATH:
+        source ~/.bashrc
+        # create the laravel project for this app:
+        laravel new webapp
+
+ 1. Add this package into your Laravel project in the parent folder of the app
+    folder:
+        
+        cd webapp/
+        composer require ryancwalsh/stack-exchange-backup-laravel:dev-master --prefer-source
+
+ 1. Run _artisan_, and choose to publish the "Provider" from this package:
+    `ryancwalsh\StackExchangeBackupLaravel\ExportStackExchangeServiceProvider`
+        
+        php artisan vendor:publish
+
+ 1. Edit your Laravel project's `.env` file to have your own StackApps values. A
+    non-working sample is below.
+
+ 1. Run
+ 
+        php artisan exportStackExchange
+         
+    (Note that `php artisan exportStackExchange --flushCache` is the option to
+    clear the cached access codevalue.)
+
+ 1. Following the instructions in the terminal, you'll use your browser to visit
+    a URL that will provide you with a temporary access token to paste into the
+    terminal.  
+    (Note: you'll find the token in the `code` part of the URL of the
+    page showing "Authorizing Application" like
+    `https://stackexchange.com/oauth/login_success?code=TLBxyz...`)
+
+ 1. Finished! The JSON files will appear in your `/storage/app/StackExchange`
+    folder.

 ## If You Use This Package, Let Me Know!
-**This is the first package that I've ever made, and I'm super curious if anyone will ever use it. If you do try it out, I'd love for you to [open an issue](https://github.com/ryancwalsh/StackExchangeBackupLaravelPHP/issues/new) to say hi** (and of course to tell me any suggestions you have).
