+===Part 1: Getting Started===
 This part follows some required loading of the sentinel imagery, such as cloud coverage settings, threshold value for vegetation only, setting the time frame and what it the final map in part 2 will resemble.
 Once you have loaded the area of interest, the next step is to select the parameters for time, cloudiness percentage, and to see what the final output will look like.
