• CodeBook.md - Describes the experiment data and the steps taken to summarize the data.
• run_analysis.R - R script to merge, clean-up, transform, and summarize the experiment data.
• data_summary.txt - Output from the run_analysis.R script.
• README.md - This file.

1. Read through the CodeBook and the run_analysis.R to understand the steps taken to transform the data from it's original raw state to it's the outputted tidy state

2. Download the data from https://d396qusza40orc.cloudfront.net/getdata%2Fprojectfiles%2FUCI%20HAR%20Dataset.zip and extract.

3. Run run_analysis.R to generate the output file.
