+>[!info] Understand messages generated Datadog
+>Datadog gives insights to the lambda functions it is monitoring. [Here](https://docs.datadoghq.com/serverless/guide/serverless_warnings/#generated-warnings) is a list of insights it can generate, and the meanings
+
+## Setup Example
+---
+We are using Python for the example. But the same setup process applies to other languages. You can refer to the [Official Guilde](https://docs.datadoghq.com/serverless/aws_lambda/installation/) for more information.
+
+Make sure you have the following completed before moving on:
+- [ ] [[Datadog Integration#AWS Integration]]
+
+There are mainly 3 things we need to do, and we can automate the process with this [Terraform Template](https://docs.datadoghq.com/serverless/aws_lambda/installation/python/?tab=terraform#installation)
+- [ ] [[#Add Datadog Lambda Extension]]
+- [ ] [[#Add Datadog Lambda Library]]
+- [ ] [[#Fine tune with Environment Variables]]
+
+>[!attention] Lambda Handler
+>We need to modify the lambda handler for certain languages like Python. Please visit [official guide](https://docs.datadoghq.com/serverless/aws_lambda/installation/python/?tab=terraform#installation) for more information
+### Add Datadog Lambda Extension
+- This serves as the [[Datadog#Agent]]
+- We can add it in as a [Lambda Layer](https://docs.aws.amazon.com/lambda/latest/dg/chapter-layers.html)
+- Refer to [2. Install the Datadog Lambda Extension](https://docs.datadoghq.com/serverless/aws_lambda/installation/python/?tab=custom#installation) for more implementation details
+
+
+
+### Add Datadog Lambda Library
+- This serves as [[Datadog ddtrace]]
+- We can add it in as a [Lambda Layer](https://docs.aws.amazon.com/lambda/latest/dg/chapter-layers.html)
+- Refer to [1. Install the Datadog Lambda library (Option A)](https://docs.datadoghq.com/serverless/aws_lambda/installation/python/?tab=custom#installation)
+
+
+### Fine tune with Environment Variables
+Below is a table of commonly used environment variables:
+
+| Variable Name                | Description                                                       | Optional |
+| ---------------------------- | ----------------------------------------------------------------- | -------- |
+| DD_API_KEY                   | Gives the permissions to pipe monitoring data to Datadog          | No       |
+| DD_SITE                      | The Datadog endpoint we want to pipe the monitoring data to       | No       |
+| DD_TRACE_ENABLED             | If we want to enable [[Trace]] or not                             | Yes      |
+| DD_ENV                       | Logical grouping name of monitoring data on the Datadog dashboard | Yes      |
+| DD_SERVICE                   | Logical grouping name of monitoring data on the Datadog dashboard | Yes      |
+| DD_SERVERLESS_APPSEC_ENABLED | If we want to enable Security Signals on the Lambda function      | Yes         |
