+
+WARNING: This is an internal package to [pezkuwi-js/apps](https://github.com/pezkuwi-js/apps) so is not intended (yet) for broad use. Since these are generic components, they will move to the [pezkuwi-js/ui](https://github.com/pezkuwi-js/ui) repo once deemed stable and usable.
+
+For the existing sharable components usable in external React-based projects, take a look at the [pezkuwi-js/ui documentation](https://pezkuwi.js.org/ui/)
+
+## Overview
+
+A collection of RxJS enabled React components that operate with the [@pezkuwi/api-rx](https://github.com/pezkuwi-js/api) library. It automatically manages subscriptions on behalf of the developer, providing a number of unstyled components that can be used to construct UIs.
+
+## Usage
+
+Basic usage entails creating a `ContextProvider` and just using the components. For instance, to display the current node time,
+
+```js
+import React from 'react';
+import ReactDOM from 'react-dom';
+
+import { Api, NodeTime } from '@pezkuwi/react-query';
+
+...
+ReactDOM.render(
+  <Api>
+    <NodeTime />
+  </Api>,
+  document.querySelector('#container')
+);
+...
+```
+
+All components are provided unstyled making no assumptions on the actual use, however they all support (optionally) the `label`, `className` and `style` attributes, that can be used to style to component.
+
+```js
+...
+ReactDOM.render(
+  <Api>
+    <NodeTime className='rx-time' label='current node time:' />
+  </Api>,
+  document.querySelector('#container')
+);
+...
+```
