 **Work in progress** Cross Runtime filesystem operations for JavaScript and
 TypeScript.
 
+Available for Node, Deno Bun and Browser at
+[jsr.io/@cross/fs](https://jsr.io/@cross/fs), works seamlessly with both
+JavaScript and TypeScript.
+
 For cross rutime path operations, [jsr.io/@std/path](https://jsr.io/@std/path)
 will cover most scenarios, this library focuses on the file system operations.
 
 ## Coverage
