+# TOTALILATOR
+# ==============================================================================
+# NOTE: Must run after separator.sh script.
+
+# This script parses the files in:
+
+# - data/light-meter-1/
+# - data/light-meter-2/
+
+# and creates new CSV files which includes the total number of readings on a
+# given day and hour (of that day). The daily totals are stored at the top the
+# data/ directory at:
+
+# - data/light-meter-1-daily-totals.csv
+# - data/light-meter-2-daily-totals.csv
+
+# and the hourly breakdowns are stored in :
+
+# - light-meter-1-hourly-totals
+# - light-meter-2-hourly-totals
+
+# Because of the amount of files produced, I've made the script seperate each
+# hourly-based file into a directory corresponding to the month the readings
+# where taken. So, you should see a file structure similar to this,
+
+# data/

+# You will find I've used the date of the readings as the go-to naming
+# convention for naming files. Basically, I'm relying on the system's directory
+# structure to provide the context for the data in each file. I didn't want the
+# file names to carry the 'folder structure' and end up with longer file names
+# the deeper into the data/ directory you go. The trade-off is when viewing
+# files on their own, their file names don't provide enough context and can be
+# confusing when dealing with them in isolation (outside of the projects
+# directory structure).
