+# Serverless
+
+We're using the serverless from work for deployment
+
+```
+sls deploy
+```
+But Kurt Hutten credentials for deployment, though if you wanted to set your own account you could deploy to that if you wanted to test.
+
+## 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.
+
+```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.
