+# Skooldown
+The koolest skript addon for cooldowns
+
+With this addon you can create cooldowns with good performance, without worrying of deleting variables, etc.
+Expired cooldowns will be automatically deleted in a very optimized way.
+Everything is made with maximum performance in mind, you should be able to safely have millions of cooldowns running simultaneously.
+
+# Syntaxes
+
+Start a cooldown
+```
+(create|start) [a] cooldown %string% for %timespan%
+
+Example: start cooldown "example%player%" for 45 seconds
+```
+Stop a cooldown
+```
+(reset|stop|delete|clear) cooldown %string%"
+
+Example: stop cooldown "example%player%"
+```
+Check if cooldown is over
+```
+cooldown %string% (is|has) (finished|over|done)
+cooldown %string% is(n't| not) unfinished)
+cooldown %string% is(n't| not) (finished|over|done)
+cooldown %string% is unfinished
+
+Example:
+cooldown "example%player%" is over
+```
+Display cooldown time
+```
+set {_cd} to cooldown "example%player%"
+send "This cooldown will be over in %{_cd}%"
+```
+Extend/Reduce existing cooldown
+```
+add 5 seconds to cooldown "example%player%"
+if cooldown "example%player%" is not higher than 5 seconds:
+  remove 5 seconds from cooldown "example%player%"
+```
+
+
+# Compatibility
+- Should work on about any Minecraft version on which Skript works, cooldowns do not interact with Minecraft code in any way
+- Incompatible with WolvSK addon cooldowns due to syntax conflict, just use Skooldown instead
