+Charted is deliberately sparse in formatting and data transformation options, 
+and instead gives you a few powerful core features:
 * Rendering well on all screen sizes, including monitors
 * Re-fetching the data and updating the chart every 30 minutes
 * Moving data series into separate charts
 * Adjusting the chart type, labels/titles, and background
 
+## Supported files
+Charted currently supports the following file types:
+* .csv files
+* .tsv files
+* Google Spreadsheets (set to shareable)
+* Dropbox share links to supported files

 ## Data structure
 Charted treats the first column of the data file as the labels for the
-x-axis and all subsequent columns as y-series values. Charted does not
+x-axis. All subsequent columns are added as y-series. Charted does not
 parse the first column (x-axis), but instead always equally spaces the
 data points along the x-axis.
 
-## Supported files
-Charted currently supports csv files (including links to csv files on
-Dropbox) and Google Spreadsheets. The settings for Dropbox links and
-Google Spreadsheets must both be set to publicly shareable.
