-# Spinnaker UI
-
-![Branch Build](https://github.com/spinnaker/deck/workflows/Branch%20Build/badge.svg)
-
-## Prerequisites
-
-Make sure that [node](http://nodejs.org/download/) and [yarn](https://yarnpkg.com/en/docs/install) are installed on your system.
-The minimum versions for each are listed in package.json.
-
-## Quick Start
-
-Run the following commands (in the deck directory) to get all dependencies installed in deck and to start the server:
-
-- `yarn`
-- `yarn modules`
-- `yarn start`
-
-The app will start up on localhost:9000.
-
-When editing `core` or any other cloud provider package, please run the following in that folder
-
-- `yarn dev`
-
-If your local dev setup ends up in a corrupt state with missing npm modules, please run `yarn fixup` from deck and that
-should reset your state.
-
-## Environment variables
-
-Environment variables can be used to configure application behavior. The following lists those variables and their possible values:
-
-- `AUTH` enable/disable authentication (default is disabled, enable by setting `AUTH=enabled`).
-- `TIMEZONE` set the default timezone (default is 'America/Los_Angeles' - see http://momentjs.com/timezone/docs/#/data-utilities/ for options)
-- `DECK_CERT` enable SSL (set to the fully qualified path to cert file, and `DECK_KEY` must be set to the fully qualified path to the key file)
-
-The following external resources can be specified with environment variables:
-
-- `API_HOST` overrides the default Spinnaker API host.
-- `AUTH_ENABLED` determines whether Deck will attempt to authenticate users via Gate.
-
-For example, `API_HOST=http://spinnaker.prod.netflix.net yarn start` will run Deck with `http://spinnaker.prod.netflix.net` as the API host.
-
-## Development
-
-Deck has a combination of Angular and React, but is moving to React only. New changes made to the Deck project should use React wherever possible.
-
-## Testing
-
-To run the tests within the application, run `yarn test`.
-
-Developing things locally? You may want to run [gate](https://github.com/spinnaker/gate) locally (which runs on port 8084) as well.
-Gate is the service that hosts the spinnaker REST API.
-Then run deck like this:
-
-```
-API_HOST=http://localhost:8084 yarn start
-```
-
-## Building & Deploying
-
-To build the application, run `yarn modules && yarn build`.
-The built application lives in `build/`.
-
-## Graphql
-
-the `core` package is using graphql queries and mutation to interact with the backend (currently, only the `managed` components).
-To generate the TS types and the Apollo hooks, run `yarn graphql:generate` from `core`.
-
-## Conventions
-
-It's a work in progress, but please try to follow the [conventions here](https://github.com/spinnaker/deck/wiki/Conventions).
-
-## Customizing the UI
-
-It's certainly doable - we're in the middle of some significant changes to our build process, which should make it easier.
-For now, you can look at the [all modules](https://github.com/spinnaker/deck/tree/master/packages/) to
-get an idea how we are customizing Deck internally. Expect a lot of this to change, though, as we figure out better, cleaner
-hooks and integration points. And we're happy to provide new integration points (or accept pull requests) following
-those existing conventions if you need an integration point that doesn't already exist.
