 Or, download a release archive file from [releases](https://github.com/artus9033/chartjs-plugin-dragdata/releases).
 
-## Getting started
-
-> [!IMPORTANT]  
-> Versions `>= 3.0.0` require [manual registration](https://www.chartjs.org/docs/latest/developers/plugins.html#using-plugins).
-
-Just importing or loading the plugin script will not make dragging work. As it is usually done with chart.js plugins, since `v3.0.0` the plugin no longer self-registers globally in Chart.js and you must [register it](https://www.chartjs.org/docs/latest/developers/plugins.html#using-plugins) manually.
-
-### Global registration
-
-As any chart.js plugin, the dragdata plugin can be registered either globally for all charts (using `Chart.register(ChartJSDragDataPlugin)`), or on a per-chart basis (by specifying `plugins: [ChartJSDragDataPlugin]` in chart config).
-
-#### Bundler
-
-If you are using a bundler (e.g. Webpack, Rollup, Parcel or similar, or a framework like React or Angular):
-
-In ESM modules:
-
-```ts
-import Chart from "chart.js/auto";
-import ChartJSDragDataPlugin from "chartjs-plugin-dragdata";
-
-Chart.register(ChartJSDragDataPlugin);
-```
-
-Or in CJS modules:
-
-```js
-const Chart = require("chart.js/auto");
-const ChartJSDragDataPlugin = require("chartjs-plugin-dragdata");
-
-Chart.register(ChartJSDragDataPlugin);
-```
-
-#### Script tag
-
-Or, if you are using a script tag, both chart.js & chartjs-plugin-dragdata are available as global variables (`Chart` & `ChartJSDragDataPlugin`):
-
-```js
-Chart.register(ChartJSDragDataPlugin);
-```
-
-### Per-chart registration
-
-If you want to apply the plugin just to selected charts, you can list the plugin in chart config:
-
-```ts
-new Chart(ctx, {
-	plugins: [ChartJSDragDataPlugin],
-});
-```

 ## Configuration
 
 The following Chart.js sample configuration displays (_most_) of the available
