+## 🔑 Setup & Usage
+If you want to poke around or modify this web app, you'll have to first follow a couple of steps to ensure everything runs right.
+### System Requirements
+First off, you'll need the following:
+ - Ruby
+ - Ruby on Rails
+If you're not sure what either of those is or need pointing in the right direction [this right here](https://www.ruby-lang.org/en/documentation/installation/), is the best place to head.
+
+### Usage
+1. After you have this repository downloaded and you've made sure Ruby and Ruby on Rails are updated and on your machine `cd` into this repository, wherever it is you downloaded it to. [Not sure what 'cd' means?](https://www.git-tower.com/learn/git/ebook/en/command-line/appendix/command-line-101)
+2. Once you've `cd` into this repo, type in the command `bundle install`. This will download all the required Ruby Gems for the web app so it can function properly. [Not sure what Ruby Gems Are?](https://guides.rubygems.org/)
+3. Once the `bundle` install command above has finished downloading, ensure you are in this repository's root directory and enter the command `rails server` into your terminal. This will start the Ruby on Rails server, allowing you to now access it from your browser of choice.
+4. Type in `http://localhost:3000/` into your browser address bar and hit enter. You should now see the Rails Blog App!
+5. To access the different pages available, enter the following:
+      - localhost:3000/articles
+      - localhost:3000/authors
+      - localhost:3000/tags
+6. Please be aware that some of these pages do not have full functionality unless you are logged in. To test this, please use the following `email: admin@example.com password: admin`.
+
+## � Contributions, Issues and Forking
+
+If you have any issues setting up the project or you come across any unintended bugs or problems, please do submit an issue to the [Rails Blogger Issue Page](https://github.com/Rhelli/Rails-Blogger/issues)
+
+If you want to make your own changes, modifications or improvements, go ahead and Fork it!
+1. Fork it (https://github.com/Rhelli/Rails-Blogger/fork)
+2. Create your working branch (git checkout -b [choose-a-name])
+3. Commit your changes (git commit -am 'what this commit will fix/add/improve')
+4. Push to the branch (git push origin [chosen-name])
+5. Create a new Pull Request
