+## ⚠️⚠️⚠️ TO BE DEPRECATED ⚠️⚠️⚠️
+
+I plan to deprecate `clipboard-polyfill` in the near future, since it has finished serving its purpose of providing a simple, safe clipboard API in lieu of browser support.
+
+If you believe you have a use case that warrants continued maintenance, please [file an issue](https://github.com/lgarron/clipboard-polyfill/issues/new)!
+
+### A brief history
+
+This project dates from a time when clipboard access in JS was barely becoming possible, and [ergonomic clipboard API efforts were stalling](https://lists.w3.org/Archives/Public/public-webapps/2015JulSep/0235.html). (See [this presentation](https://docs.google.com/presentation/d/1Ix2rYi67hbZoIQsd85kspkUPLi8Q-PZopy_AtfafHW0/) for a bit more context.) Fortunately, [an ergonomic API with the same functionality](https://developer.mozilla.org/en-US/docs/Web/API/Clipboard) is now available in all modern browsers since 2020:
+
+- 2015: Browsers [start supporting](https://caniuse.com/mdn-api_document_execcommand_copy) the [defunct](https://w3c.github.io/editing/docs/execCommand/) `document.execCommand("copy")` call (with [many, many issues](./experiment/Conclusions.md)).
+- 2015: Started this project as `clipboard.js` (half a year before @zenorocha picked [the same name](https://github.com/zenorocha/clipboard.js) 😛).
+- 2016: Renewed discussions about an async clipboard API (e.g. [proposal doc](https://docs.google.com/document/d/1QI5rKJSiYeD9ekP2NyCYJuOnivduC9-tqEOn-GsCGS4/edit#), [`crbug.com/593475`](https://bugs.chromium.org/p/chromium/issues/detail?id=593475)).
+- 2017: Renamed this project to `clipboard-polyfill` to reflect a `v2` API overhaul aligned with the draft spec.
+- 2018: Browsers [start supporting](https://caniuse.com/mdn-api_clipboard_writetext) `navigator.clipboard.writeText()`.
+- 2020: Browsers [start supporting](https://caniuse.com/mdn-api_clipboard_write) `navigator.clipboard.write()` (including `text/html` support).
+
+Thanks to Gary Kacmarcik, Hallvord Steen, and others for helping to bring the [async clipboard API](https://w3c.github.io/clipboard-apis/) to life!
