+# Web Server Using Amazon EC2
+
+This example deploys a simple AWS EC2 virtual machine running a Python web server.
+
+## Deploying the App
+
+To deploy your infrastructure, follow the below steps.
+
+### Prerequisites
+
+1. [Install Pulumi](https://www.pulumi.com/docs/get-started/install/)
+2. [Configure AWS Credentials](https://www.pulumi.com/docs/intro/cloud-providers/aws/setup/)
+
+### Steps
+
+After cloning this repo, from this working directory, run these commands:
+
+1. Create a new stack, which is an isolated deployment target for this example:
+
+    ```bash
+    $ pulumi stack init
+    ```
+
+2. Set the required configuration variables for this program:
+
+    ```bash
+    $ pulumi config set aws:region us-east-1
+    ```
+
+3. Stand up the VM, which will also boot up your Python web server on port 80:
+
+    ```bash
+    $ pulumi up
+    ```
+
+4. After a couple minutes, your VM will be ready, and two stack outputs are printed:
+
+    ```bash
+    $ pulumi stack output
+    Current stack outputs (2):
+    OUTPUT          VALUE
+    publicHostName  ec2-53-40-227-82.compute-1.amazonaws.com
+    publicIp        53.40.227.82
+    ```
+
+5. Thanks to the security group making port 80 accessible to the 0.0.0.0/0 CIDR block (all addresses), we can curl it:
+
+    ```bash
+    $ curl $(pulumi stack output publicIp)
+    Hello, World!
+    ```
+
+6. From there, feel free to experiment. Simply making edits and running `pulumi up` will incrementally update your VM.
+
+7. Afterwards, destroy your stack and remove it:
+
+    ```bash
+    $ pulumi destroy --yes
+    $ pulumi stack rm --yes
+    ```
