Welcome to City Limits!          (1/10)
As the new mayor, it's time to run
things YOUR way. For better or worse...
Will you lead the clean energy front,
or will you put profits before people?
`, `
Moving Via Mouse                 (2/10)
To move around, press and hold your
middle mouse button while moving your
mouse, or press right click to center
the camera on an area immediately.
`, `
Moving Via Keyboard              (3/10)
You can also use your keyboard to move
by pressing any of the arrow keys or
W/A/S/D. Try using your mouse and/or
keyboard to move the camera around now.
`, `
Zoning Areas                     (4/10)
Structures are built according to how
you zone areas of land. Demand for each
category (Residential, Commercial,
Industrial) is shown in the sidebar.
`, `
Did You Know?                    (5/10)
Powering an area requires more input
energy than the resulting electricity.
In fact, only a third of the energy is
transmitted as usable electricity. 
`, `
Building Blocks of a City        (6/10)
Structures require power, sewer and
transportation in order to function.
This is all facilitated via roads and
underground wiring and piping.
`, `
Did You Know?                    (7/10)
Meat-based diets require much more
energy, land and water resources than
vegetarian and especially vegan diets.
Animal farms are a source of pollution.
`, `
Power to the People              (8/10)
Build a power plant, then zone a few
areas for residential development.
Connect the power plant to the newly
zoned areas with a road.
`, `
Did You Know?                    (9/10)
It takes large amounts of water to
convert fossil fuels into electricity.
Converting solar and wind energy uses
negligible amounts of water.
`, `
Collecting Taxes                (10/10)
Each year, taxes are collected from the
residents of the city. The tax rate you
set determines how appealing your city
is, and whether or not it can survive.
