+# babel-plugin-extend-docs
+
+A plugin which rewrites imports and templates according to a configuration.
+This enables the reuse of existing documentation from source packages while still using your extensions code.
+
+## Installation
+
+```bash
+npm i -D babel-plugin-extend-docs
+```
+
+We want to only execute `babel-plugin-extend-docs` on the actual files we want to modify/extend.
+We recommend using [babel overrides](https://babeljs.io/docs/en/options#overrides) for it.
+
+👉 _babel.config.js_
+
+```js
+const extendDocsConfig = {
+  rootPath: process.cwd(), // or `path.resolve('./')` as plugin needs to know the rootPath of your project
+  changes: [
+    // possible changes as described below
+  ],
+};
+
+module.exports = {
+  overrides: [
+    {
+      // plugin will only be executed on files that match this pattern
+      test: ['./node_modules/source-library/demos/**/*.js'],
+      plugins: [['babel-plugin-extend-docs', extendDocsConfig]],
+    },
+  ],
+};
+```
+
+## Features
+
+- Renames named imports and all it's usage
+- Adjusts import paths
+- Replace tags in template literals
+
+## A Change
+
+A change is what gets placed between in the extendDocsConfig within the `changes` array.
+
+> automating the generation of changes is optional but encouraged
+
+It has the following possibilities:
+
+```js
+changes: [
+  {
+    description: 'MyCounter', // not needed but can be added for easier reading of the config
+    variable: {
+      // see below
+    },
+    tag: {
+      // see below
+    },
+  },
+];
+```
+
+### Paths
+
+Both `variable` and `tag` are required to have a `paths` array which defines how to remap import paths.
+As demos can use multiple ways to import all of them needs to be written down in the config.
+
+```js
+paths: [
+  { from: './index.js', to: './my-extension/index.js' },
+  { from: '../index.js', to: '../my-extension/index.js' },
+  { from: './src/MyCounter.js', to: './my-extension/index.js' },
+  { from: '../src/MyCounter.js', to: '../my-extension/index.js' },
+],
+```
+
+## Replacement of tags
+
+We have an existing demo code which we want to reuse.
+
+```js
+import { LitElement, html } from 'lit-element';
+import './my-counter.js';
+class MyApp extends LitElement {
+  render() {
+    return html`
+      <h1>Example App</h1>
+      <my-counter></my-counter>
+    `;
+  }
+}
+customElements.define('my-app', MyApp);
+```
+
+We created a "better" version of `<my-counter>` so we would like to use that in the demo.
+Our extension is called `<my-extension>` and is available in `./my-extension/my-extension.js`.
+
+Within `babel-plugin-extend-docs` we can define to replace the tag + it's import.
+
+```js
+tag: {
+  from: 'my-counter',
+  to: 'my-extension',
+  paths: [{ from: './my-counter.js', to: './my-extension/my-extension.js' }],
+}
+```
+
+### Result of Replacement of tags
+
+```js
+import { LitElement, html } from 'lit-element';
+import './my-extension/my-extension.js';
+class MyApp extends LitElement {
+  render() {
+    return html`
+      <h1>Example App</h1>
+      <my-extension></my-extension>
+    `;
+  }
+}
+customElements.define('my-app', MyApp);
+```
+
+## Replacement of classes
+
+We have an existing demo code which we want to reuse.
+
+```js
+import { LitElement, html } from 'lit-element';
+import { MyCounter } from './src/MyCounter.js';
+class TenCounter extends MyCounter {
+  inc() {
+    this.count += 10;
+  }
+}
+customElements.define('ten-counter', TenCounter);
+class MyApp extends LitElement {
+  render() {
+    return html`
+      <h1>Example App</h1>
+      <ten-counter></ten-counter>
+    `;
+  }
+}
+customElements.define('my-app', MyApp);
+```
+
+We created a "better" version of `MyCounter` so we would like that `TenCounter` now extends it instead.
+
+Within `babel-plugin-extend-docs` we can define to replace the class + it's import.
+
+```js
+variable: {
+  from: 'MyCounter',
+  to: 'MyExtension',
+  paths: [
+    { from: './src/MyCounter.js', to: './my-extension/index.js' },
+  ],
+},
+```
+
+### Result of Replacement of classes
+
+```js
+import { LitElement, html } from 'lit-element';
+import { MyExtension } from './my-extension/index.js';
+class TenCounter extends MyExtension {
+  inc() {
+    this.count += 10;
+  }
+}
+customElements.define('ten-counter', TenCounter);
+class MyApp extends LitElement {
+  render() {
+    return html`
+      <h1>Example App</h1>
+      <ten-counter></ten-counter>
+    `;
+  }
+}
+customElements.define('my-app', MyApp);
+```
+
+## Full Demo & Api Example
+
+You can run the example locally via `npm run start` or look at its [source code](https://github.com/ing-bank/lion/tree/master/packages/babel-plugin-extend-docs/demo/).
+_Note we are configuring babel via the [server.config.js](https://github.com/ing-bank/lion/tree/master/packages/babel-plugin-extend-docs/demo/server.config.js)_
+
+👉 _babel.config.js_
+
+```js
+const path = require('path');

+  rootPath: path.resolve('./demo'),
+  changes: [
+    {
