From the README: Quick start

With an AI coding agent

Install the aws-emulator skill, then ask your agent to set up the emulator. This needs the AWS CLI version 2.35.0 or later. See Getting started with an AI coding agent.

aws agent-toolkit add-skill --skill-name aws-emulator --region us-east-1

Server mode (CLI and any SDK)

Linux: install the RPM or Debian package and run aws-emulator. See Getting started on Linux.
Windows / macOS: run the emulator in a container built from a short Dockerfile. See Getting started with Docker.

Point your SDK at a running emulator by setting environment variables. See Pointing your AWS SDK at AWS Emulator.

Embedded mode (Rust tests)

Add the emulator as a dev-dependency and run it in-process, one isolated instance per test. There is no endpoint URL, certificate, or environment variable to set. Your test wires the emulator's HTTP client straight into the SDK client. See Getting started with embedded mode, and Building from source below for its build cost.

Did you get it running?
