To be notified through the terminal of when there are Pokémon nearby your location, first you need to find your coordinates.
If you need help finding them, check out whereamirightnow.com and keep note of your latitude & longitude.
For example, these are the coordinates for the World Trade Center;
Latitude: 40.712774
Longitude: -74.013408
We can now pipe these coordinates into the CLI like so;
pokevision watch \
--lat=40.712774 \
--lon=-74.013408 \
--name="World Trade Center"Note that we also passed in a name. This will become more useful later...
In your terminal you should see something like this;
Psyduck (https://maps.google.com/maps?q=40.712361737605,-74.013532760584&z=19)
47m away from World Trade Center

Information like; the name of the Pokémon, it's distance away from the location, and the time before it disappears are all provided.
