+- ⚡ built for speed
+- ⬇️ low-level compiler for parsing markdown without caching or blocking for long periods of time
+- ⚖️ light-weight while implementing all markdown features from the supported flavors & specifications
+- 🌐 works in a browser, on a server, or from a command line interface (CLI)
+
+## Demo
+
+Checkout the [demo page](https://marked.js.org/demo/) to see marked in action ⛹️
+
+## Docs
+
+Our [documentation pages](https://marked.js.org) are also rendered using marked 💯
+
+Also read about:
+
+* [Options](https://marked.js.org/#/USING_ADVANCED.md)
+* [Extensibility](https://marked.js.org/#/USING_PRO.md)
+
+## Compatibility
+
+**Node.js:** Only [current and LTS](https://nodejs.org/en/about/releases/) Node.js versions are supported. End of life Node.js versions may become incompatible with Marked at any point in time.
+
+**Browser:** Not IE11 :)
+
+## Installation
+
+**CLI:**
+
+```sh
+npm install -g marked
+```
+
+**In-browser:**
+
+```sh
+npm install marked
+```
+
+## Usage
+
+### Warning: 🚨 Marked does not [sanitize](https://marked.js.org/#/USING_ADVANCED.md#options) the output HTML. Please use a sanitize library, like [DOMPurify](https://github.com/cure53/DOMPurify) (recommended), [sanitize-html](https://github.com/apostrophecms/sanitize-html) or [insane](https://github.com/bevacqua/insane) on the *output* HTML! 🚨
+
+```
