-Takes a path string, an array of path strings, a [glob][node-glob] string or an array of [glob][node-glob] strings as `globs` to watch on the filesystem. Also optionally takes `options` to configure the watcher and a `fn` to execute when a file changes.
+Takes a path string, an array of path strings, a [glob][micromatch] string or an array of [glob][micromatch] strings as `globs` to watch on the filesystem. Also optionally takes `options` to configure the watcher and a `fn` to execute when a file changes.
+
+__Note: As of 5.0.0, globs must use `/` as the separator character because `\\` is reserved for escape sequences (as per the Bash 4.3 & Micromatch specs). This means you can't use `path.join()` or `__dirname` in Windows environments. If you need to use `path.join()`, you can use [normalize-path][normalize-path] against your paths afterwards. If you need to use `__dirname`, you can set it as the `cwd` option that gets passed directly to [chokidar][chokidar]. The [micromatch docs][micromatch-backslashes] contain more information about backslashes.__
