+Walkthrough: Adding a New Panel to the Dashboard
+================================================
+
+The following is for creating a new panel called "**examplePanel**."
+
+1. Create a folder named `examplePanel` inside the `components/pages/dashboard/panels` folder.
+1. Create 3 files in the new folder. See the individual example files for more details and comments inline.
+    - [examplePanel.js](/src/components/pages/dashboard/panels/_examplePanel/examplePanel.js) - main component for the panel
+    - [examplePanel.scss](/src/components/pages/dashboard/panels/_examplePanel/examplePanel.scss) - styles for the new panel
+    - [index.js](/src/components/pages/dashboard/panels/_examplePanel/index.js) - exports for the new panel
+1. Add the new panel to the main panel export file: [dashboard/panels/index.js](/src/components/pages/dashboard/panels/index.js).
+    ```js
+    export * from './examplePanel';
+    ```
+1. Add the panel header to the translations file, [translations.json](../../public/locales/en/translations.json). [i18next][i18next] is used for internationalization.
+    ```json
+    "examplePanel": {
+      "header": "Example Panel",
+    },
+    ```
+1. In the [examplePanel.js](/src/components/pages/dashboard/panels/_examplePanel/examplePanel.js), import the `Panel` components.
+    ```js
+    import {
+      Panel,
+      PanelHeader,
+      PanelHeaderLabel,
+      PanelContent,
+    } from 'components/pages/dashboard/panel';
+    ```
+1. In the render method, use the various `Panel` components to ensure consistency with others. Then, add whatever components are needed inside `PanelContent`.
+    ```jsx
+    <Panel>
+      <PanelHeader>
+        <PanelHeaderLabel>{t('examples.panel.header')}</PanelHeaderLabel>
+      </PanelHeader>
+      <PanelContent className="example-panel-container">
+        {t('examples.panel.panelBody')}
+      </PanelContent>
+    </Panel>
+    ```
+1. Add your panel to the [dashboard.js](/src/components/pages/dashboard/dashboard.js) page. Size the `Cell` for the panel according to how much space it will need. See [grid.scss](/src/components/pages/dashboard/grid/grid.scss) for the available grid-cell styles.
+    ```jsx
+    <Cell className="col-4">
+      <ExamplePanel t={t} />
+    </Cell>
+    ```
+1. **Congratulations!** Run the application and navigate to the Dashboard page.  You should see your new panel in action.
+
+1. Now, you can edit the panel to do what you want. Send props with any data you need. If mapping data and actions from a reducer, consider using the "container" approach described in the [Adding a New Grid](addNewGrid.md) walkthrough.
+
+1. Optional customizations:
+    1. Add an `Indicator` to the header to show pending state.
+        ```jsx
+        { isPending && <Indicator size="small" /> }
+        ```
+    1. Use a `PanelOverlay` to show pending state. This example uses an `Indicator`, but other components or messages could be placed here.
+        ```jsx
+        { isPending && <PanelOverlay><Indicator /></PanelOverlay> }
+        ```
+    1. Use `PanelError` and `AjaxError` to show error state.
+        ```jsx
+        { error && <PanelError><AjaxError t={t} error={error} /></PanelError> }
+        ```
