 ## testing changes locally
 
-Honestly it's a pain in the neck, for a number of reasons.
-
 You'll need to have Docker installed
 
-Because of the way the docker containers to be deployed as lambdas on aws are somewhat specialised for the purpose we're using `docker-compose` to spin one up for each function/endpoint. But more work needs to be done to get this to work with the app locally.
+Because of the way the docker containers to be deployed as lambdas on aws are somewhat specialised for the purpose we're using `docker-compose` to spin one up for each function/endpoint. So we've added a aws-emulation layer
+
+first cd into this folder `cd api/src/docker`
+then
 
 ```bash
 docker-compose up --build
 ```
 The first time you run the, when it has to build the main image it will take some time, but launching again will be quicker.
 
+After which we'll also spin up a light express server to act as an emulator to transform some the request from the front end into how the lambda's expect them.
+```
+yarn install
+yarn emulate
+```
+You can now change the url in `web/src/helpers/cadPackages/openScadController.js` from the aws url to `http://localhost:8080`
+
+If you change anything in the `api/src/docker/openscad` directory, you will need to stop the docker process and restart it (will be fairly quick if you're only changing the js)
