Examples with aws cli used directly

[grav]

Would be nice with creating/updating and invocation examples in the README where the aws cli is used directly. For instance, wrt invokation:

aws lambda invoke \
--invocation-type RequestResponse \
--function-name work-magic \
--region eu-west-1 \
--log-type Tail \
--payload '{"magic-word": "my-lambda-project-token", "spell":"delay-promise"}' \
outfile.txt
