+# Sprint Mod For minetest
+
+Allows players to sprint by holding E, by default increasing their travel speed
+by 80% and their jump speed by 10%. Also adds a stamina bar that goes down when
+the player sprints and goes up they're not sprinting.
+
+This mod is compatible with the HUD bars [hudbars] mod, but does not depend on
+it. In this case, a green HUD bar will be displayed, also showing a number.
+If this mod is not present, a standard statbar with 0-20 “half-arrows” is shown,
+which is a bit more coarse than the HUD bar version.
+
+This mod is by rubenwardy, and is based on a mod by GunshipPenguin but heavily
+rewritten to be more performant.
+
+License: MIT (see license.txt)
+
+## Settings
+
+1.0 represents normal speed so 1.5 would mean that a sprinting player would
+travel 50% faster than a walking player and 2.4 would mean that a sprinting
+player would travel 140% faster than a walking player.
+
+* `sprint_speed`- 1 is normal walking speed, defaults to 1.8.
+* `sprint_jump` - 1 is normal jump speed, defaults to 1.1.
+* `sprint_stamina` - How long the sprint lasts in seconds, defaults to 20.
+* `sprint_heal_rate` - Multiply this by the stamina to get how long it takes to recharge, defaults to 0.5.
+* `sprint_min` - The minimum value at which you can start sprinting, defaults to 0.5.
+
+## Recharging when the sprint key is down
+
+Follow the instructions in comments marked by `##number##`.
