 # OpenCost
 
-Welcome to the OpenCost plugin!
+Welcome to the [OpenCost](https://opencost.io) plugin!
 
 Currently this is a port of the [OpenCost UI](https://github.com/opencost/opencost/tree/develop/ui), but we will continue to expand it to expose any relevant data or pre-configured views that may be preferred.

 ## Installation
 
+1.  Add the OpenCost dependency to the `packages/app/package.json`:
+    ```sh
+    # From your Backstage root directory
+    yarn add --cwd packages/app @backstage/plugin-opencost
+    ```
+2.  Add the `OpenCostPage` to your `packages/app/src/App.tsx`:
+
+```tsx
+import { OpenCostPage } from '@backstage/plugin-opencost';
+```
+
+and
+
+```tsx
+<FlatRoutes>
+  …
+  <Route path="/opencost" element={<OpenCostPage />} />
+</FlatRoutes>
+```
+
+3.  Add link to OpenCost to your sidebar
+
+    ```typescript
+    // packages/app/src/components/Root/Root.tsx
+     import MoneyIcon from '@material-ui/icons/MonetizationOn';
+
+     ...
+
+     export const Root = ({ children }: PropsWithChildren<{}>) => (
+       <SidebarPage>
+         <Sidebar>
+           ...
+          <SidebarItem icon={MoneyIcon} to="opencost" text="OpenCost" />
+           ...
+         </Sidebar>

 ## Configuration
 
 ## TODO
 
-* Document installation and configuration
-* More testing
-* Use the OpenCost mascot for the sidebar logo
-* Use the Backstage proxy to communicate with the OpenCost API
-* Convert AllocationReport.js to use the [Backstage Table](https://backstage.io/storybook/?path=/story/data-display-table--default-table)
-* Allow for user-provided default reports and/or disabling controls
-* Support multiple hard-coded reports
-* Fork(?) to support Kubecost, which could provide Alerts and Recommendations, similar to the Cost Explorer plugin
-* clean up deprecation warnings and upgrade to all the latest React components
