 # aws-lambda-send-ses-email
-AWS Lambda function to send emails using Amazon SES
+
+An AWS Lambda function to send emails using Amazon SES.
+
+The primary purpose of this function is to provide a server-side back-end for sending emails
+from static websites.
+
+By using AWS Lambda, we can eliminate the need to host your (almost) static website on
+EC2 instances.
+
+## Installation
+
+1. Create an IAM Role for executing AWS Lambda functions. 
+2. Give your new IAM Role the following policy:
+
+```
+{
+    "PolicyName" : "aws-lambda-send-ses-email-policy",
+    "PolicyDocument" : {
+        "Version" : "2012-10-17",
+        "Statement" : [
+            {
+                "Effect" : "Allow",
+                "Action" : [
+                    "logs:CreateLogGroup",
+                    "logs:CreateLogStream",
+                    "logs:PutLogEvents"
+                ],
+                "Resource" : "arn:aws:logs:*:*:*"
+            },
+            {
+                "Effect" : "Allow",
+                "Action" : [
+                    "cloudwatch:PutMetricData"
+                ],
+                "Resource" : "*"
+            },
+            {
+                "Effect" : "Allow",
+                "Action" : [
+                    "ses:SendEmail"
+                ],
+                "Resource" : "*"
+            },
+            {
+                "Effect" : "Allow",
+                "Action" : [
+                    "s3:GetObject"
+                ],
+                "Resource" : "*"
+            }
+        ]
+    }
+}
+```
+
+3. Create an S3 bucket to store the email template(s).
+
+4. Create a template file (HTML or text file). A sample file is provided in the `Templates/` folder.
+
+5. Upload the template file to your S3 bucket.
+
+6. Download the latest release ZIP file.
+
+7. Edit `config.js` providing your own details. Put your customized file back into the ZIP file.
+
+8. Create an AWS Lambda function using your custom ZIP file as the source code.
+
+## Usage
+
+Call the Lambda function with any number of properties. The properties will be passed on to the
+template file for substitution.
+
+### Notable Parameters
+
+email: This parameter is required. It's used to populate the "Reply-To" field of the email.
+
+name: This parameter is optional, but when omitted, the value from `email` will be used.
+

+
+```
+<p>
