 Webiny currently hosts two official drivers - MySQL and Memory drivers. Additional drivers may be added (eg. PostgreSQL or MongoDB) as the need arises in the near future.
 
 ## Installation
-`yarn install webiny-entity`
+`yarn add webiny-entity`
 
 ## Quick Example
 In general, the first step in defining a new entity is to extend a base Entity class, and then define attributes in class constructor. To quickly get an impression on how it works, please consider the following examples:

+# webiny-plugins
+
+A simple registry for plugins that stores all plugins in a shared object.
+The only requirement for a plugin is to have a `name` and a `type` properties. The rest is entirely up to you.
+
+There is nothing spectacular going on under the hood, just a simple object for storing references and a few utility functions.
+However, this simple library has helped us greatly while developing modular APIs and UIs in React.
+
+## Installation
+`yarn add webiny-plugins`
+
+## Adding a plugin
+```
+import { addPlugin } from "webiny-plugins";
+
+// Add a plugin
+addPlugin({
+    name: "my-plugin",
+    type: "say-hi",
+    salute: () => "Hi!"
+});
+
+addPlugin({
+    name: "my-second-plugin",
+    type: "say-hi",
+    salute: () => "Yo!"
+});
+```
+
+## Getting plugins by type
+```
+// anywhere in your app
+import { getPlugins } from "webiny-plugins";
+
+const plugins = getPlugins("say-hi");
+plugins.forEach(plugin => {
+    // Call "salute" function
+    plugin.salute();
+});
+```
+
+## Getting a single plugin by name
+```
+// anywhere in your app
+import { getPlugin } from "webiny-plugins";
+
+const plugin = getPlugin("my-plugin");
+// Call "salute" function
+plugin.salute();
+```
+
+## Removing a plugin
+```
+// anywhere in your app
+import { removePlugin } from "webiny-plugins";
+
+removePlugin("my-plugin");
+```
