-This module is part of the [AWS Cloud Development Kit](https://github.com/aws/aws-cdk) project.
+[Amazon FSx](https://docs.aws.amazon.com/fsx/?id=docs_gateway) provides fully managed third-party file systems with the
+native compatibility and feature sets for workloads such as Microsoft Windows–based storage, high-performance computing,
+machine learning, and electronic design automation.
+
+Amazon FSx supports two file system types: [Lustre](https://docs.aws.amazon.com/fsx/latest/LustreGuide/index.html) and
+[Windows](https://docs.aws.amazon.com/fsx/latest/WindowsGuide/index.html) File Server.
+
+## FSx for Lustre
+
+Amazon FSx for Lustre makes it easy and cost-effective to launch and run the popular, high-performance Lustre file
+system. You use Lustre for workloads where speed matters, such as machine learning, high performance computing (HPC),
+video processing, and financial modeling.
+
+The open-source Lustre file system is designed for applications that require fast storage—where you want your storage
+to keep up with your compute. Lustre was built to solve the problem of quickly and cheaply processing the world's
+ever-growing datasets. It's a widely used file system designed for the fastest computers in the world. It provides
+submillisecond latencies, up to hundreds of GBps of throughput, and up to millions of IOPS. For more information on
+Lustre, see the [Lustre website](http://lustre.org/).
+
+As a fully managed service, Amazon FSx makes it easier for you to use Lustre for workloads where storage speed matters.
+Amazon FSx for Lustre eliminates the traditional complexity of setting up and managing Lustre file systems, enabling
+you to spin up and run a battle-tested high-performance file system in minutes. It also provides multiple deployment
+options so you can optimize cost for your needs.
+
+Amazon FSx for Lustre is POSIX-compliant, so you can use your current Linux-based applications without having to make
+any changes. Amazon FSx for Lustre provides a native file system interface and works as any file system does with your
+Linux operating system. It also provides read-after-write consistency and supports file locking.
+
+### Installation
+
+Import to your project:
 
 ```ts
 import * as fsx from '@aws-cdk/aws-fsx';
 ```
+
+### Basic Usage
+
+Setup required properties and create:
+
+```ts
+const stack = new Stack(app, 'Stack');
+const vpc = new Vpc(stack, 'VPC');
+
+const fileSystem = new LustreFileSystem(stack, 'FsxLustreFileSystem', {
+  lustreConfiguration: { deploymentType: LustreDeploymentType.SCRATCH_2 },
+  storageCapacityGiB: 1200,
+  vpc,
+  vpcSubnet: vpc.privateSubnets[0]});
+```
+
+### Connecting
+
+To control who can access the file system, use the `.connections` attribute. FSx has a fixed default port, so you don't
+need to specify the port. This example allows an EC2 instance to connect to a file system:
+
+```ts
+fileSystem.connections.allowDefaultPortFrom(instance);
+```
+
+### Mounting
+
+The LustreFileSystem Construct exposes both the DNS name of the file system as well as its mount name, which can be
+used to mount the file system on an EC2 instance. The following example shows how to bring up a file system and EC2
+instance, and then use User Data to mount the file system on the instance at start-up:
+
+```ts
+const app = new App();
+const stack = new Stack(app, 'AwsCdkFsxLustre');
+const vpc = new Vpc(stack, 'VPC');
+
+const lustreConfiguration = {
+  deploymentType: LustreDeploymentType.SCRATCH_2,
+};
+const fs = new LustreFileSystem(stack, 'FsxLustreFileSystem', {
+  lustreConfiguration,
+  storageCapacityGiB: 1200,
+  vpc,
+  vpcSubnet: vpc.privateSubnets[0]});
+
+const inst = new Instance(stack, 'inst', {
+  instanceType: InstanceType.of(InstanceClass.T2, InstanceSize.LARGE),
+  machineImage: new AmazonLinuxImage({
+    generation: AmazonLinuxGeneration.AMAZON_LINUX_2,
+  }),
+  vpc,
+  vpcSubnets: {
+    subnetType: SubnetType.PUBLIC,
+  },
+});
+fs.connections.allowDefaultPortFrom(inst);
+
+// Need to give the instance access to read information about FSx to determine the file system's mount name.
+inst.role.addManagedPolicy(ManagedPolicy.fromAwsManagedPolicyName('AmazonFSxReadOnlyAccess'));
+
+const mountPath = '/mnt/fsx';
+const dnsName = fs.dnsName;
+const mountName = fs.mountName;
+
+inst.userData.addCommands(
+  'set -eux',
+  'yum update -y',
+  'amazon-linux-extras install -y lustre2.10',
+  // Set up the directory to mount the file system to and change the owner to the AL2 default ec2-user.
+  `mkdir -p ${mountPath}`,
+  `chmod 777 ${mountPath}`,
+  `chown ec2-user:ec2-user ${mountPath}`,
+  // Set the file system up to mount automatically on start up and mount it.
+  `echo "${dnsName}@tcp:/${mountName} ${mountPath} lustre defaults,noatime,flock,_netdev 0 0" >> /etc/fstab`,
+  'mount -a');
+```
+
+### Importing
+
+An FSx for Lustre file system can be imported with `fromLustreFileSystemAttributes(stack, id, attributes)`. The
+following example lays out how you could import the SecurityGroup a file system belongs to, use that to import the file
+system, and then also import the VPC the file system is in and add an EC2 instance to it, giving it access to the file
+system.
+
+```ts
+const app = new App();
+const stack = new Stack(app, 'AwsCdkFsxLustreImport');
+
+const sg = SecurityGroup.fromSecurityGroupId(stack, 'FsxSecurityGroup', '{SECURITY-GROUP-ID}');
+const fs = LustreFileSystem.fromLustreFileSystemAttributes(stack, 'FsxLustreFileSystem', {
+    dnsName: '{FILE-SYSTEM-DNS-NAME}'
+    fileSystemId: '{FILE-SYSTEM-ID}',
+    securityGroup: sg
+});
+
+const vpc = Vpc.fromVpcAttributes(stack, 'Vpc', {
+    availabilityZones: ['us-west-2a', 'us-west-2b'],
+    publicSubnetIds: ['{US-WEST-2A-SUBNET-ID}', '{US-WEST-2B-SUBNET-ID}'],
+    vpcId: '{VPC-ID}'
+});
+const inst = new Instance(stack, 'inst', {
+  instanceType: InstanceType.of(InstanceClass.T2, InstanceSize.LARGE),
+  machineImage: new AmazonLinuxImage({
+    generation: AmazonLinuxGeneration.AMAZON_LINUX_2
+  }),
+  vpc,
+  vpcSubnets: {
+    subnetType: SubnetType.PUBLIC,
+  }
+});
+fs.connections.allowDefaultPortFrom(inst);
+```
+
+## FSx for Windows File Server
+
+The L2 construct for the FSx for Windows File Server has not yet been implemented. To instantiate an FSx for Windows
+file system, the L1 constructs can be used as defined by CloudFormation.
