+# OpenCost
+
+Welcome to the OpenCost plugin!
+
+_This plugin was created through the Backstage CLI_
+
+## Getting started
+
+Your plugin has been added to the example app in this repository, meaning you'll be able to access it by running `yarn start` in the root directory, and then navigating to [/opencost](http://localhost:3000/opencost).
+
+You can also serve the plugin in isolation by running `yarn start` in the plugin directory.
+This method of serving the plugin provides quicker iteration speed and a faster startup and hot reloads.
+It is only meant for local development, and the setup for it can be found inside the [/dev](./dev) directory.
+
+## IDEAS
+
+opencost logo on side
+
+### variables for:
+
+ opencost URL
+ days of data (14d default)
+ costs warning lines
+
+top graph:
+pick with specific query pattern
+dates adjustable
+
+table underneath
+
+TrendLines
+
+Tabs on different namespaces/etc.?
+
+get currencies from cost-insights
