 ## Install the Windows Subsystem for Linux
 
 The Windows Subsystem for Linux allows you to use a full Linux environment via Bash on Ubuntu. This means you can install BLT's prerequisites on your Windows workstation in a similar way as you would on a Linux or Mac environment.

+## Known issues and quirks
+
+As the WSL is a beta feature it is expected that some features may contain bugs or be incomplete.
+
+At the time of writing these are the currently known issues which you may encounter.
+
+  1. [Only portions of procfs are implemented, and there is limited inotify support](https://github.com/Microsoft/BashOnWindows/issues/216). This will impact things like Gulp where you commonly want to actively 'watch' for filesystem changes. In that particular instance you can use [gulp-watch](https://www.npmjs.com/package/gulp-watch) which polls periodically instead.
+  2. [Network enumeration is not supported](https://github.com/Microsoft/BashOnWindows/issues/468). This will impact networking functions commonly required by popular frontend packages and utilities (e.g Browsersync). There are workarounds discussed in the GitHub issue.
+  3. [Permissions on /dev/tty are sometimes incorrect](https://github.com/Microsoft/BashOnWindows/issues/617). This can prevent ssh connectivity keyboard input cannot be read (required when entering a passphrase). A workaround is discussed in the GitHub issue.
