+## What is it for?

+
+It's packaged as a docker image, and is automatically installed as part of the Galoy helm charts.
+
+With a default installation, Galoy-Tips can be access under `tips.domain.com`.
+
+Galoy-Tips usese query, mutation, and subscription operations from the Galoy's graphql API endpoints `api.domain.com` as defined in [schema.graphql](https://github.com/GaloyMoney/galoy/blob/main/src/graphql/main/schema.graphql)
+
+## How to run this repo locally?
+
+In the project directory, you can run:
+
+```sh
+yarn install
+export GRAPHQL_URI="https://api.domain.com/graphql"
+export GRAPHQL_SUBSCRIPTION_URI="wss://api.domain.com/graphql"
+yarn start
+```
+
+This will run the app in the development mode.
+
+Open [http://localhost:3000](http://localhost:3000) to view it in the browser.

+### How to build for production?
+
+In the project directory, you can run:
+
+```sh
+yarn install
+export GRAPHQL_URI="https://api.domain.com/graphql"
+export GRAPHQL_SUBSCRIPTION_URI="wss://api.domain.com/graphql"
