-# Development Principles
-
-> **Note:** This document outlines guidances behind some development decisions
-> behind the Hipster Shop demo application.
-
-### Minimal configuration
-
-Running the demo locally or on GCP should require minimal to no
-configuration unless absolutely necessary to run critical parts of the demo.
-
-Configuration that takes multiple steps, especially such as creating service
-accounts should be avoided.
-
-### App must work well outside GCP
-
-Demo application should work reasonably well when it is not deployed to GCP
-services. The experience of running the application locally or on GCP should
-be close.
-
-For example:
-- OpenCensus prints the traces to stdout when it cannot connect to GCP.
-- Stackdriver Debugging tries connecting to GCP multiple times, eventually gives
-  up.
-
-### Running on GCP must not reduce functionality
-
-Running the demo on the GCP must not reduce/lose any of the capabilities
-developers have when running locally.
-
-For example: Logs should still be printed to stdout/stderr even though logs are
-uploaded to Stackdriver Logging when on GCP, so that developers can use "kubectl
-logs" to diagnose each container.
-
-### Microservice implementations should not be complex
-
-Each service should provide a minimal implementation and try to avoid
-unnecessary code and logic that's not executed.
-
-Keep in mind that any service implementation is a decent example of “a GRPC
-application that runs on Kubernetes”. Keeping the source code short and
-navigable will serve this purpose.
-
-It is okay to have intentional inefficiencies in the code as they help
-illustrate the capabilities of profiling and diagnostics offerings.

-## `hack/` 
-
-This directory provides scripts for building and pushing Docker images, and tagging new demo
-releases. 
-
-### env variables 
-
-- `TAG` - git release tag / Docker tag. 
-- `REPO_PREFIX` - Docker repo prefix to push images. Format: `$user/$project`.  Resulting images will be of the
-  format `$user/$project/$svcname:$tag` (where `svcname` = `adservice`, `cartservice`,
-  etc.)
-
-### scripts 
-
-1. `./make-docker-images.sh`: builds and pushes images to the specified Docker repository.
-2. `./make-release-artifacts.sh`: generates a combined YAML file with image $TAG at: 
-   `./release/kubernetes-manifests/demo.yaml`. 
-3. `./make-release.sh`: runs scripts 1 and 2, then runs `git tag` / pushes updated manifests to master.
