Quick instructions:

- Control box is in the top right corner.

- Type the name of a town into the Go To box and press enter

- Click "Create" to create a new waypoint

- While it is green you can drag it around, of course you can zoom in to place
it precisely

- Click on it to view and edit details

- Elevation is automatically retrieved from Google whenever you move the
waypoint

- Click on "Lock" to lock the waypoint in place (it turns yellow)

- Double-click on a waypoint to zoom to it

- Double-click on the map to zoom out and see all waypoints

- Click on "Download" to download all the waypoints in Geo (GPSDump) format

You can edit existing waypoint sets:

- Drag and drop an existing waypoint file (Geo, CompeGPS format) onto the
"Upload a file" box in the top right corner

- You need to click on a waypoint and "unlock" it to be able to edit it

- When you have finished adding, removing and deleting waypoints click on
"Download"

Other features:

- You can put a radius around each turnpoint

- You can also type waypoint names into the Go To box to go directly to a
waypoint

- The description can be retrieved from Google when you click on the refresh
button by the input box - this sets the description to be the postal address of
the location - it saves you having to look up or type in village names!

- You can cycle through all the waypoints using the left and right arrow
buttons: great for checking all the waypoints in a set!

- You can download the waypoint coordinates in a text format ready to print out
and give to your pilots

- To make a turnpoint map, all you need to do is take a screenshot!

On my TODO list I have:

- Make it prettier

- Preserve turnpoint radii

- Give some options for choosing colours
