+We have tested with 4 lighthouse base stations, which cover around 8x8x3 meters of flying space. The software supports
+up to 16 base stations, which should make it possible to add more base stations to cover multiple rooms and maybe larger

 guide on our web to get a good understanding of basic use.
 
 1. Make sure that all base stations have a unique channel like 1, 2, 3, 4, 5 and so on.  Use the "Set BS channel" button in the Lighthouse tab
 in the python client for this task
-2. In placement of the LH base stations, make sure that they must overlap, but avoid too many in one spot. The lighthouse deck can not handle more than 4 visible
-at the same time.

 3. Re-flash the Crazyflie with support for more base stations. Run `make menuconfig` and go to the `Expansion deck configuration`
 menu and set `Max number of base stations` to the desired value. Note: more base stations use more RAM. Build the code and
 flash it to the Crazyflie, see the documentation in this repo for [instructions on building and flashing](/docs/building-and-flashing/build.md)
