+[![Netlify Status](https://api.netlify.com/api/v1/badges/056dda4a-4444-4c24-a854-c4b1944d35ca/deploy-status)](https://stimulus-content-loader.netlify.com)
+
+## Getting started
+
+A Stimulus controller to asynchronously load HTML from an url.
+
+## Installation
+
+```bash
+$ yarn add stimulus-content-loader
+```
+
+And use it in your JS file:
+```js
+import { Application } from "stimulus"
+import ContentLoader from "stimulus-content-loader"
+
+const application = Application.start()
+application.register("content-loader", ContentLoader)
+```
+
+## Usage
+
+In your controller:
+```ruby
+class PostsController < ApplicationController
+  def comments
+    render partial: 'posts/comments', locals: { comments: @post.comments }
+  end
+end
+```
+
+In your routes:
+```ruby
+Rails.application.routes.draw do
+ressources
+  get :comments, to: 'posts#comments'
+end
+```
+
+In your view:
+```html
+<div
+  data-controller="content-loader"
+  data-content-loader-url="<%= comments_path %>"
+>
+  <i class="fas fa-spinner fa-spin"></i> Loading comments...
+
+  This content will be replaced by the content of the `posts/comments` partial generated by Rails.
+</div>
+
+<div
+  data-controller="content-loader"
+  data-content-loader-url="<%= comments_path %>"
+  data-content-loader-refresh-interval="5000"
+>
+  This content will be reloaded every 5 seconds.
+</div>
+
+<div
+  data-controller="content-loader"
+  data-content-loader-url="/message.html"
+>
+  This content will be replaced by the content of the `/message.html` page in your public folder.
+</div>
+
+<div
+  data-controller="content-loader"
+  data-content-loader-url="/message.html"
+  data-content-loader-lazy-loading=""
+>
+  This content will be replaced only when the element become visible thanks to Intersection Observers.
+</div>
+
+<div
+  data-controller="content-loader"
+  data-content-loader-url="/message.html"
+  data-content-loader-lazy-loading=""
+  data-content-loader-lazy-loading-root-margin="30px"
+  data-content-loader-lazy-loading-threshold="0.4"
+>
+  You can customize the Intersection Observer options.
+</div>
+
+<div
+  data-controller="content-loader"
+  data-content-loader-url="/message.html"
+  data-content-loader-lazy-loading=""
+  data-content-loader-refresh-interval="5000"
+>
+  You can combine lazy loading and refresh interval. The timer will start only after the first fetch.
+</div>
+```
+
+## Configuration
+
+| Attribute | Default | Description | Optional |
+| --------- | ------- | ----------- | -------- |
+| `data-content-loader-refresh-interval` | `undefined` | Interval in milliseconds to reload content. | ✅ |
+| `data-content-loader-lazy-loading` | `undefined` | Fetch content when element is visible. | ✅ |
+| `data-content-loader-lazy-loading-root-margin` | `0px` | rootMargin option for Intersection Observer. | ✅ |
+| `data-content-loader-lazy-loading-threshold` | `0` | threshold option for Intersection Observer. | ✅ |
+
+
+## Extending Controller
+
+You can use inheritance to extend the functionality of any Stimulus components.
+
+```js
+import ContentLoader from "stimulus-content-loader"
+
+export default class extends ContentLoader {
+  connect() {
+    super.connect()
+    console.log("Do what you cant here.")
+  }
+}
+```
+
+These controllers will automatically have access to targets defined in the parent class.
+
+If you override the connect, disconnect or any other methods from the parent, you'll want to call `super.method()` to make sure the parent functionality is executed.
+
+## Development
+
+### Project setup
+```bash
+$ yarn install
+$ yarn dev
+```
+
+### Linter
+[Prettier](https://prettier.io/) and [ESLint](https://eslint.org/) are responsible to lint and format this component:
+```bash
+$ yarn lint
+$ yarn format
+```
+
+## Credits
+
+This controller is inspired by the [official Stimulus example](https://stimulusjs.org/handbook/working-with-external-resources).
