+Derive Rust code to safely and ergonomically manipulate GraphQL queries.
+
+This library does not provide any networking, caching or other client functionality yet, it is just meant to make it easy to interact with a GraphQL query and the corresponding response in a strongly typed way. Making a request can be as simple as this:
 
 ```rust
 #[derive(GraphQLQuery)]
 #[gql(
-    query = "/graphql/queries/my_query.graphql",
-    schema = "/graphql/schema.graphql"
+    query_path = "src/graphql/queries/my_query.graphql",
+    schema_path = "src/graphql/schema.json"
 )]
 struct MyQuery;
 
 fn perform_my_query(variables: &my_query::Variables) -> Result<(), failure::Error> {
     let body = MyQuery::expand(variables);
     let client = reqwest::Client::new();
-    let res: HttpResponse<graphql_client::Response<my_query::ResponseData>> = client.post("/graphql", body)?;
-    println!("{:#?}", res.body);
+    let mut res: HttpResponse<graphql_client::Response<my_query::ResponseData>> = client.post("/graphql").json(&body).send()?;
+    println!("{:#?}", res.text());
+    Ok(())
 }
 ```
 
+The paths in the `gql` attribute are relative to the directory where your `Cargo.toml` is located.
+
+The GraphQL schema language and schema.json are both supported as sources for the schema.
+
+`serde_derive` needs to be visible in the context of the `GraphQLQuery` derive (add it as an `extern crate`).
+
 ## Features
 
-* Strongly typed query variables
-* Strongly typed response
+- Strongly typed query variables
+- Strongly typed responses
+- Works in the browser (WebAssembly)
+
+Integration with different HTTP libraries is planned, although building one yourself is trivial (just send the constructed request payload as JSON with a POST request to a GraphQL endpoint, modulo authentication).
 
-### Planned features
+There is an embryonic CLI for downloading schemas - the plan is to make it something similar to `apollo-codegen`.
 
-* Strongly typed subscriptions
-* Query string minification (e.g. for embedding in a browser wasm app, and for minimizing payload size)
-* A command line interface in addition to the custom derive for generating code and downloading schemas
 
-## What is generated?
+## What is generated?
 
-* A module named after the struct under derive, which contains:
-  * A `ResponseData` struct implementing `serde::Deserialize`
-  * A `Variables` struct meant to contain the variables expected by the query
-* An impl for the `GraphQLQuery` trait for the struct under derive
