+= Lua library: `Achievements` =
+WARNING: The achievements system is still very bare bones. It might be subject to major changes in future. This library should only be used internally by Hedgewars at this point.
+
+This is simple library for awarding an achievement to the player, to be used in missions. They are not meant for multiplayer.
+
+An achievement in Hedgewars is a simple award given for doing something awesome or difficult in a mission, or winning a mission in a great way.
+Achievements are a hidden feature in Hedgewars so far and far from complete.
+One example achievement is “Lively Lifeguard” in the mission “That Sinking Feeling” for rescuing all hogs.
+
+== `awardAchievement(name, statText, capgrp)` ==
+Awards an achievement with name `name` to player.
+
+Currently, this only displays a caption and adds a mention in the stat screen.
+
+* `name`: Name of achievement.
+* `statText`: Optional. If set as string, this text will be shown in the stats screen. If `nil`, a default text is used.
+* `capgrp`: Optional. Caption group of `AddCaption` to be used. Default is `capgrpMessage2`. If `false`, no caption is shown.
+
+For consistent style, treat the name like a title is written in the English language. Good: “Naughty Ninja”. Bad: “naughty ninja”.
