 Variable Penalty Dynamic Time Warping for aligning GC-MS chromatograms to a master signal and more. With the appropriate penalty this method performs good alignment without altering the shape of peaks in chromatography data.
 
 ## Installation
-Please install the package in R directly using the commands:
+The package can be installed from GitHub:
