 > In cryptography, a Caesar cipher, also known as Caesar’s cipher, the shift cipher, Caesar’s code or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet. For example, with a left shift of 3, D would be replaced by A, E would become B, and so on.
 
 In this project, the caeser cipher is implemented using Ruby. This project is part of The Odin Project's Ruby Programming curriculum. The project information can be found [here](https://www.theodinproject.com/courses/ruby-programming/lessons/caesar-cipher).

 ## Sub Strings
 ### Information
 This function takes a word/phrase and a dictionary of words (as an array) as inputs to the functions. The function then returns a hash with each word found from the dictionary found in the word/phrase and the number of occurences. This project is implemented using Ruby as part of The Odin Project's Ruby Programming curriculum. The project information can be found [here](https://www.theodinproject.com/courses/ruby-programming/lessons/sub-strings).

 ## Stock Picker
 ### Information
+This program takes an array of stock prices and tells the user what the best day to buy and sell the said stock is. These two days are returned, as well as the profit margin for these days. This project is implemented using Ruby as part of The Odin Project's Ruby Programming curriculum. The project information can be found [here](https://www.theodinproject.com/courses/ruby-programming/lessons/stock-picker).

 ## Bubble Sort
 ### Information
+This program takes an array and then returns the array sorted. This program is implemented using a bubble sort. In a bubble sort, each element is compared to the one next to it and they are swapped if the one on the left is larger than the one on the right. This continues until the array is eventually sorted. This project is implemented using Ruby as part of The Odin Project's Ruby Programming curriculum. The project information can be found [here](https://www.theodinproject.com/courses/ruby-programming/lessons/bubble-sort).
+The expected output for this project should be:
+```
+> bubble_sort([4,3,78,2,0,2])
+=> [0, 2, 2, 3, 4, 78]
