+# fb-watchman
+
+`fb-watchman` is a filesystem watcher that uses the
+[Watchman](https://facebook.github.io/watchman/) file watching service from
+Facebook.
+
+Watchman provides file change notification services using very
+efficient recursive watches and also allows more advanced change matching and
+filesystem tree querying operations using
+[a powerful expression syntax](https://facebook.github.io/watchman/docs/file-query.html#expressions).
+
+## Install
+
+You should [install Watchman](
+https://facebook.github.io/watchman/docs/install.html) to make the most of this
+module.
+
+Then simply:
+
+```
+$ npm install fb-watchman
+```
+
+## Key Concepts
+
+- Watchman recursively watches directories.
+- Each watched directory is called a `root`.
+- You must initiate a `watch` on a `root` using the `watch-project` command prior to subscribing to changes
+- Rather than separately watching many sibling directories, `watch-project` consolidates and re-uses existing watches relative to a project root (the location of your `.watchmanconfig` or source control repository root)
+- change notifications are relative to the project root
+
+## How do I use it?
+
+[Read the NodeJS watchman documentation](https://facebook.github.io/watchman/docs/nodejs.html)
