# Welcome to GraphiQL
# GraphiQL is an in-browser tool for writing, validating,

# type schema and live syntax and validation errors
# highlighted within the text.
#
# GraphQL queries typically start with a "{" character.
# Lines that start with a # are ignored.
#
# An example GraphQL query might look like:
