-If you're crazy enough to use this in the browser, you can just grab the
-JSON file using [jsDelivr](https://www.jsdelivr.com/). It is recommended to
-replace `master` with [a release tag](https://github.com/jshttp/mime-db/tags)
-as the JSON format may change in the future.
+If you intend to use this in a web browser, you can conveniently access the JSON file via [jsDelivr](https://www.jsdelivr.com/), a popular CDN (Content Delivery Network). To ensure stability and compatibility, it is advisable to specify [a release tag](https://github.com/jshttp/mime-db/tags) instead of using the 'master' branch. This is because the JSON file's format might change in future updates, and relying on a specific release tag will prevent potential issues arising from these changes.
