- Definition
A UV-map or just "UV" is the information in a model, which parts of a texture are shown on which parts of a model. UVs can overlap and hence cause several parts to use the same area on the texture.

- Editing a UV Map
You can edit a UV-map trough the UV window in the top left.
Make sure to have a cube selected which you want to UV map and freely resize/move the selection box in the UV window.
You cannot resize the UV selection if you're using BoxUV

**- What do the value fields below the UV window mean? **
Per-face uv: The first two values are the x/y position (with 0/0 being in the top left
corner) of the uv map, and the last two values its width and height.
_Box uv: The 2 values are the x/y position of the uv map. The size of the uv-map depends on the size of the respective cube.

- I don't wanna bother with any of that, just let me draw on the model!:
Select all elements (Ctrl+A) and, create a new texture and make sure to selec "Template" as type.
This will create a new texture that will keep already existing texture information, but assigns each element a unique section in the texture.

And as you're using Box UV, I assume you're making an entity model, keep in mind that entity models do not have backface culling.
Meaning you can effectively only texture 1 side of a pane.
