+# LibSpellRange-1.0
+
+## Background
+
+Blizzard's `IsSpellInRange` API has always been very limited - you either must have the name of the spell, 
+or its spell book ID. Checking directly by spellID is simply not possible. 
+Now, since Mists of Pandaria, Blizzard changed the way that many talents and specialization spells work - 
+instead of giving you a new spell when leaned, they replace existing spells. These replacement spells do 
+not work with Blizzard's IsSpellInRange function whatsoever; this limitation is what prompted the creation of this lib.
+
+## Usage
+
+**LibSpellRange-1.0** exposes an enhanced version of IsSpellInRange that:
+
+*   Allows ranged checking based on both spell name and spellID.
+*   Works correctly with replacement spells that will not work using Blizzard's IsSpellInRange method alone.
+
+### `SpellRange.IsSpellInRange(spell, unit)` - Improved `IsSpellInRange`
+
+#### Parameters
+
+- `spell` - Name or spellID of a spell that you wish to check the range of. The spell must be a spell that you have in your spellbook or your pet's spellbook.
+- `unit` - UnitID of the spell that you wish to check the range on.
+
+#### Return value
+
+Exact same returns as [the built-in `IsSpellInRange`](http://wowprogramming.com/docs/api/IsSpellInRange.html)
+
+#### Usage
+
+``` lua
+-- Check spell range by spell name on unit "target"
+local SpellRange = LibStub("SpellRange-1.0")
+local inRange = SpellRange.IsSpellInRange("Stormstrike", "target")
+
+-- Check spell range by spellID on unit "mouseover"
+local SpellRange = LibStub("SpellRange-1.0")
+local inRange = SpellRange.IsSpellInRange(17364, "mouseover")
+```
+
+### `SpellRange.SpellHasRange(spell)` - Improved `SpellHasRange`
+
+#### Parameters
+
+- `spell` - Name or spellID of a spell that you wish to check for a range. The spell must be a spell that you have in your spellbook or your pet's spellbook.
+
+#### Return value
+
+Exact same returns as [the built-in `SpellHasRange`](http://wowprogramming.com/docs/api/SpellHasRange.html)
+
+#### Usage
+
+``` lua
+-- Check if a spell has a range by spell name
+local SpellRange = LibStub("SpellRange-1.0")
+local hasRange = SpellRange.SpellHasRange("Stormstrike")
+
+-- Check if a spell has a range by spellID
+local SpellRange = LibStub("SpellRange-1.0")
+local hasRange = SpellRange.SpellHasRange(17364)
+```
