 <!-- ABOUT THE PROJECT -->
 ## About The Project
 
-TBD
-
-### Basic Example
-
-TBD
+This library provides utilities to facilitate the resolution of GraphQL based on which fields are requested.
 
 ### Built With
 * [Typescript](https://www.typescriptlang.org/)
 * [GraphQL](https://graphql.org)
 * [Jest](https://jestjs.io)

 <!-- GETTING STARTED -->
 ## Getting Started
 
 ### Installation
 
-TBD
+```
+npm install graphql-introfields
+```
 
 <!-- USAGE EXAMPLES -->
 ### Usage
 
-TBD
+#### Basic Example
+
+With the following schema:
+```graphql
+type Employee {
+  id: ID!
+  name: String!
+}
+
+type VideoStore {
+  id: ID!
+  employees: [Employee!]!
+  manager: Employee!
+}
+
+type Query {
+  videostore: VideoStore
+}
+
+schema {
+  query: Query
+}
+```
+
+And with the following resolvers:
+
+```javascript
+import { resolveBasedOnFields } from 'graphql-introfields';
+
+const resolvers = {
+  Query: {
+    videostore: getVideoStoreData,
+  },
+  VideoStore: {
+    manager: resolveBasedOnFields((fields) => {
+      // if you know that only the `id` field is asked for, and it's present on the root, you can prevent
+      // unnecessary resolution of the manager field (which may be an over-the-network request).
+      if (fields.length === 1 && fields[0].name.value === 'id') {
+        return (root, _args, _ctx, _info) => ({ id: root['managerId'] });
+      }
+      return (root, _args, _ctx, _info) => getEmployeeById(root.managerId);
+    }),
+  },
+}
+```
+
+The following query doesn't actually call  `getEmployeeById`:
+
+```graphql
+query {
+  videostore {
+    manager {
+      id
+    }
+  }
+}
+```
+
+#### `resolveIDFieldFromRoot`
+
+The above use-case is actually available as a provided utility.
+
+```js
+import { resolveIDFieldFromRoot } from 'graphql-introfields';
+const resolvers = {
+  videostore: {
+    manager: resolveIDFieldFromRoot(
+      'managerId',
+      (root) => getEmployeeById(root.managerId)
+    )
+  }
+}
+```
