@@ -179,7 +182,6 @@ The basic scalar types supported are:
 - `float32`, `float64` (NDC scalar type: `Float`)
 - `bool` (NDC scalar type: `Boolean`)
 - `time.Time` (NDC scalar type: `DateTime`, represented as an [ISO formatted](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString) string in JSON)

 Alias scalar types will be inferred to the origin type in the schema.
