# Building with Go {% hint style="info" %} This page was generated from content adapted from the [AWS Developer Guide](https://github.com/awsdocs/aws-lambda-developer-guide.git) {% endhint %} ## Deploy .zip file archives * **Note**\ If you have not already done so, you must install [git](https://git-scm.com/) and then add the `git` executable to your Windows `%PATH%` environment variable. * **Note**\ When you create a Go Lambda function using the AWS CLI, the value of the handler setting you define is the executable file name. For more information, see [AWS Lambda function handler in Go](https://github.com/kevinslin/aws-reference-notes/blob/main/services/aws_lambda/golang-handler.md). ## Tracing * **Important**\ **ADOT is the preferred method for instrumenting your Lambda functions**. We recommend using ADOT for all new applications. However, due to the flexibility OpenTelemetry offers, your Lambda function invocations may experience cold start latency increases. If you're optimizing for low-latency and also do not require OpenTelemetry's advanced capabilities such as telemetry correlation and dynamically configurable backend destinations, you may want to use the AWS X-Ray SDK over ADOT. * **Note**\ You cannot configure the X-Ray sampling rate for your functions. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://awsnotes.dendron.so/serverless/aws-lambda/topics/building-with-go.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
