 # Overview of AWS EC2 FPGA Development Kit
 
-The AWS EC2 FPGA Development Kit is provided by AWS to support development and runtime on [AWS FPGA instances](https://aws.amazon.com/ec2/instance-types/f1/).  Amazon EC2 FPGA instances are high-performance compute instances with field programmable gate arrays (FPGAs) that are programmed to create custom hardware accelerations in EC2. F1 instances are easy to program and AWS provides everything needed to develop, simulate, debug, compile and run hardware accelerated applications.  Using the [FPGA developer AMI](https://aws.amazon.com/marketplace/pp/B06VVYBLZZ), developers create an FPGA design. Once the FPGA design (also called CL - Custom logic) is complete, developers create the Amazon FPGA Image (AFI), and deploy it to the F1 instance in just a few clicks. AFIs are reusable, shareable and can be deployed in a scalable and secure way.

 # Getting Started
 
 ### New to AWS?
-If you are new to AWS, we recommend you start with [AWS getting started training](https://aws.amazon.com/getting-started/), to learn how to use AWS EC2, S3 and the AWS CLI.  These services are required to start developing accelerations for AWS FPGAs. For example, creating an AFI requires [AWS CLI](http://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html) installed and the execution of `aws s3 <action>` (`aws ec2 create-fpga-image`).  AWS FPGA generation and EC2 F1 instances are supported in us-east-1 (N. Virginia), us-west-2 (Oregon), eu-west-1 (Ireland) and us-gov-west-1 (GovCloud US).
+If you have never used AWS before, we recommend you start with [AWS getting started training](https://aws.amazon.com/getting-started/), and focus on the basics of the [AWS EC2](https://aws.amazon.com/ec2/) and [AWS S3](https://aws.amazon.com/s3/) services.  Understanding the fundamentals of these services will make it easier to work with AWS FPGAs.

 ### New to AWS FPGAs and setting up a development environment?
-The developer kit is supported for Linux operating systems only.  You have the choice to develop on AWS EC2 using the [FPGA developer AMI](https://aws.amazon.com/marketplace/pp/B06VVYBLZZ) or on-premises. Within a linux environment, you should execute `git clone https://github.com/aws/aws-fpga.git` to download the latest release to your EC2 Instance or local server. Using a SSH connection, execute `git clone [email protected]:aws/aws-fpga.git`. [To get help with connecting to Github via SSH](https://help.github.com/articles/connecting-to-github-with-ssh/).

 # FPGA Developer AMI
 
-The [FPGA developer AMI](https://aws.amazon.com/marketplace/pp/B06VVYBLZZ) is available on the AWS marketplace without a software charge and includes free tools and drivers needed for FPGA development on EC2 instances. FPGA development runs on several [EC2 instance types](https://aws.amazon.com/ec2/instance-types/). Given the large size of the FPGA used inside the AWS FPGA instances, the implementation tools require 32GiB Memory (ex: c4.4xlarge, m4.2xlarge, r4.xlarge, t2.2xlarge). c4.4xlarge and c4.8xlarge would provide the fastest execution time with 30 and 60GiB of memory respectively. Developers who want to save on cost, could start coding and run simulations on low-cost instances, like t2.2xlarge, and move to the aforementioned larger instances to run the synthesis of their acceleration code.
