+All players send out their commands simultaneously, so there is no player order.
 
 The amount of turns an expedition will travel is equal to the ceiled euclidean distance
 between its origin and destination planet.
 
+Each turn, one additional ship will be constructed on each player-owned planet.
+Neutral planets do not construct ships.

 Ships will only battle on planets. Combat resolution is simple: every ship destroys one enemy

-You can code your bot in python 3.10. You have the entire stdlib at your disposal.

+## Writing your bot
 
-### TL;DR
+You can code a bot in python 3.10 using the [web editor](/editor). A working example bot is provided.
+If you'd like to use a different programming language, or prefer coding on your own editor,
+you can try [local development](/docs/local-development).

+As logging to stdout will be interpreted as commands by the game server, we suggest you log to stderr.  
+In python, you can do this using
+
+```python
+print("hello world", file=sys.stderr)
+```
+
+Output written to stderr will be displayed alongside the match replay.

+Feel free to launch some test matches to get the hang of it!
