 # Ruby - Function to Swap Array Elements
-## Table of Contents

+- [Information](https://github.com/fussykyloren/ruby-array-swap#information)
+- [Status](https://github.com/fussykyloren/ruby-array-swap#status)
+- [Instructions](https://github.com/fussykyloren/ruby-array-swap#instructions)
 ## Information
+This function implements a typical swap function for an array. This is not easily accessible in Ruby (to my knowledge) so I made a function for me but am happy to share it with you!
+This function is built with Ruby v2.6.5p114. To check your version, run:
+```
+ruby -v
+```
 ## Status
+At this time, the project is __*finished*__.
 ## Instructions
+To run these program, Ruby v2.6.3p62 (or a compatible version) will need to be installed. To check the version of ruby you are using, run this command in terminal:
+```
+ruby -v
+```
+If you do not have ruby installed, follow these [instructions](https://www.ruby-lang.org/en/documentation/installation/).
+After ruby is installed, you should clone this repository to a place easily accessible to you using this command in terminal:
+```
+git clone https://github.com/fussykyloren/ruby-array-swap.git
+```
+Your github username and password should be requested. If not, don't worry about it.
+After the repository is cloned, you will need to change the directory to where the game example is saved. To to use the fibonacci programs, run this command next:
+```
+cd [LOCATION_OF_CLONED_REPOSITORY]
+```
+Now you can move the ruby file to where you will need to use it! This can be done using this command:
+```
+mv [LOCATION_OF_CLONED_REPOSITORY]/swap.rb [LOCATION_TO_MOVE_FILE]
+```
+Or if you'd prefer, you can copy the file using this command:
+```
+cp [LOCATION_OF_CLONED_REPOSITORY]/swap.rb [LOCATION_TO_MOVE_FILE]
+```
