+
+To load `.gql` and `.graphql` files, first install the [`graphl-tag.macro`](https://www.npmjs.com/package/graphql-tag.macro) package by running
+
+```sh
+npm install --save graphl-tag.macro
+```
+
+Alternatively you may use `yarn`:
+
+```sh
+yarn add graphql-tag.macro
+```
+
+Then, whenever you want to load `.gql` or `.graphql` files, import the `loader` from the macro package:
+
+```js
+import { loader } from 'graphql.macro';
+
+const query = loader('./foo.graphql');
+```
+
+And your results get automatically inlined! This means that if the file above, `foo.graphql`, contains the following:
+
+```graphql
+gql`
+  query {
+    hello {
+      world
+    }
+  }
+`;
+```
+
+The previous example turns into:
+
+```javascript
+const query = {
+  'kind': 'Document',
+  'definitions': [{
+    ...
+  }],
+  'loc': {
+    ...
+    'source': {
+      'body': '\\\\n  query {\\\\n    hello {\\\\n      world\\\\n    }\\\\n  }\\\\n',
+      'name': 'GraphQL request',
+      ...
+    }
+  }
+};
+```
+
+You can also use the `gql` template tag the same way you would use the non-macro version from `graphql-tag` package with the added benefit of inlined parsing results.
