-Status

+Validating schemas:
 
-The parser can parse virtually all of the query syntax:
+```lua
+local validate = require 'validate'
+validate(schema, ast)
+```
 
-- Documents
-- Definitions
-  - OperationDefinition
-  - FragmentDefinition
-- Selections
-- Fields
-- Aliases
-- Arguments
-- FragmentSpreads and InlineFragments
-- All value types (scalars, enums, lists, objects, variables).
-- VariableDefinitions (typed)
-- Directives
+Running tests
+---
 
-The type system supports scalars, objects, enums, input objects, interfaces, and unions.  The built in scalars are
-also provided (ints, floats, strings, etc.), as well as the two wrapper types (non null and list).
