Start with documentation/server/guides/deploying/aws-sam-lambda.md and compare it with the proposed server-guides/Sources/ServerGuides.docc/deploying/aws-sam-lambda.md destination. Translate the article, add it to server-guides/Sources/ServerGuides.docc/Documentation.md under Deployment, then run the two listed Swift documentation commands. Done includes successful analysis and preview, workgroup review, and the post-publication redirect updates.
