    Chapter text goes here. Indentation will be ignored, but it can be useful for you when you're
    writing. The indentation helps to visually separate chapters and sections.

# NOTE:
# -------------------------------------------------------------------------------------------------
# The bash (Bourne Again SHell) language commands use whitespace instead of commas and parentheses.
#
# All arguments are separated by whitespace, flags are preceeded by dashes (-), and separate 
# commands are delineated by semicolons (;).
#
# For flags, typically, single dashes refer to a single character flag (e.g., rm -r) which makes it
# easy to combine multiple single-character flags with only a single dash (e.g., rm -r), and thus
# two-dashes (--) tends to refer to multi-character (word-like) flags (e.g., pip --force-reinstall)

# Note that in macOS as a Unix-like System (BSD-based), a majority
# of the Unix Commandline Tools are already pre-installed and used
# as part of the Operating System (OS). This, however, causes the
# problem that many of these tools are version-locked for the intent
# of retaining compatibility within the OS itself, meaning that they
# are often old/out-of-date. As such, we can use `brew` (Homebrew)
# in macOS to install the latest versions of these utilities. But,
