 the appropriate structures, causing issues with non-existing types ( thanks to Hasura ), for example `bigint` which was difficult to export.
 Therefore, I present you the simple client to which you can copy & paste your graphQL query, variables and you are good to go.
 
-## Usage
+## Features
+
+* Executing GraphQL queries as they are, without types declaration
+* Compressing produced queries
+* Support for additional headers
+* Support for gzip compression ( built into Hasura )

+## Working with results

+I'm using an amazing library [tidwall/gjson](https://github.com/tidwall/gjson) to parse the results and extract information required in further steps and I strongly recommend this approach as the easiest and close to painless.
