Hi, just beginning to use Graphcool. Wanted to know more about GraphQl IDL, but the link to https://www.graph.cool/docs/faq/graphql-idl-schema-definition-language-kr84dktnp0 seems to be broken. E.g. from Twitter as well as from the first hit on Google if you are looking for "graphql idl".

Try reading this post: https://blog.graph.cool/graphql-sdl-schema-definition-language-6755bcb9ce51 It gives a general overview of SDL (Schema Definition Language, which is same thing as IDL). You can also check

Schemas and Types

section of GraphQL documentation (http://graphql.org/)
