 This mod alone is not aimed directly at players. Briefly, the point of this mod is to help other mods to implement temporary status effects for players in a clean and consistant way.
 Here is the information which may be relevant to you: Your current status effects are shown on the HUD on the right side, along with a timer which shows the time until the effect gets disabled. It is possible for the server to disable this feature entirely. Some status effects may also be hidden and are never exposed to the HUD.

 ## Information for server operators
 By default, this mod stores the effects into the file `playereffects.mt` in the current world path every 10 seconds. On a regular server shutdown, this file is also written to. The data in this file is read when the mod is started.
