-== Global available Constants ==
+== Globally available variables and constants ==
+The following variables are made available by Hedgewars in Lua and can be used to quickly query a value. Lua scripts schould normally *not* write to these variables, only read from them.
+
+=== General variables and constants ===
+Here are some unsorted variables or constants which are available in Lua. You shouldn’t write to most of them.
 
-<blockquote><tt>LAND_WIDTH</tt>, <tt>LAND_HEIGHT</tt>
-</blockquote>
-<blockquote><tt>!ScreenWidth</tt>, <tt>!ScreenHeight</tt>, <tt>!WaterLine</tt></blockquote>
+|| *Identifier* || *Description* ||
+|| `LAND_WIDTH` || The width of the landscape in pixels ||
+|| `LAND_HEIGHT` || The height of the landscape in pixels ||
+|| `WaterLine` || The y position of the water, used to determine at which position stuff drowns. Use `SetWaterLine` to change. ||
+|| `ClansCount` || Number of clans in the game (teams with the same color belong to one clan) ||
+|| `TeamsCount` || Number of teams in the game ||
+|| `TurnTimeLeft` || Number of game ticks (milliseconds) left until the current turn ends. You can change this variable directly. ||
+|| `GameTime` || Number of total game ticks ||
+|| `TotalRounds` || Number of rounds that have passed ||
+|| `CurrentHedgehog` || The hedgehog gear that is currently in play ||
 
-Game flags:
-
-<blockquote><tt>gfForts, gfMultiWeapon, gfBorder, gfSolidLand, gfDivideTeams, gfLowGravity, gfLaserSight, gfInvulnerable, gfMines, gfVampiric, gfKarma, gfArtillery, gfOneClanMode, gfRandomOrder, gfKing, gfPlaceHog, gfSharedAmmo, gfDisableGirders, gfExplosives, gfDisableLandObjects, gfAISurvival, gfInfAttack, gfResetWeps, gfResetHealth, gfPerHogAmmo, gfDisableWind, gfMoreWind, gfTagTeam</tt></blockquote>
+=== !GameFlags ===
+The !GameFlags are used to store simple boolean settings of the game. All game flags are stored together in a bitmask. You don’t have to worry about this too much, the functions in [LuaAPI#GameFlags] do all the bitmask handling for you.
 
-*Note:* A few of these, e.g. gfResetHealth (and probably gfTagTeam) are not yet exposed to lua.
