+# <center>FeelingLucky v1.2.0 - A luck driven mechanics plugin.</center>
+
+## <center><u><span style="color:blue">Plugin Description:</u></center>
+
+### <center><u><span style="color:cyan">For All Users:</u></center>
+
+<b>FeelingLucky</b> is a mechanics plugin designed to expand upon the Luck attribute which Minecraft provides.
+Each user is assigned a tangible Luck stat, which can be viewed by using <b><span style="color:violet">/luck info</color></b>.
+Users can <i>increase</i> their luck stat by using a rabbit's foot, 
+or increase their luck and their luck multiplier by consuming a special rabbits foot purchased from a Butcher villager.
+<b><span style="color:red">Beware</b> though, if you take damage from guardian lasers or a witch's potion, 
+there's a chance your luck will <i>decrease</i> instead.
+
+### <center><u><span style="color:pink">For Administrators:</u></center>
+Admins can modify values in the configuration file, as well as modify individual user's luck stat.
+Admins can set, reset, add to, and take from player's luck stat.
+Admins can also reload the main configuration, as well as individual and all player configurations.
+For this, the command is <b><span style="color:violet">/luck reload -m</color></b> for the main config, 
+<b><span style="color:violet">/luck reload</color></b> to reload all player configurations, and <b><span style="color:violet">/luck reload -p <i>PLAYER_NAME</i></span></b> to reload individual player configuration files.
+Server owners and/or individuals with console access can run /rgc to regenerate the main configuration file in the case that there are values missing, corrupted, or invalid.
+
+## <center><u><span style="color:blue">Server Requirements:</u></center>
+
+In order to run <b>FeelingLucky</b> v<b>1.1.0</b>, the latest version of Paper or Spigot is required.
+
+#### <center><span style="color:red">Note: Paper is REQUIRED for this plugin to run. Spigot is not supported, however Spigot support is currently in progress.</center></span>
+
+### <center>Note: If you are migrating from an Alpha build, the plugin configuration folder will need to be regenerated.</center>
