Instructions on avoiding exception when running mojo on Marshmallow.

 Mojo
 ====
 
 Mojo is an effort to extract a common platform out of Chrome's renderer and
 plugin processes that can support multiple types of sandboxed content, such as
 HTML, Pepper, or NaCl.
 
 ## Set-up and code check-out

 To build for Android, first make sure that your checkout is [configured](#configure-android) to build
 for Android. After that you can use the mojob script as follows:
 ```
 $ mojo/tools/mojob.py gn --android
 $ mojo/tools/mojob.py build --android
 ```
 
 The result will be in out/android_Debug. If you see javac compile errors,
 [make sure you have an up-to-date JDK](https://code.google.com/p/chromium/wiki/AndroidBuildInstructions#Install_Java_JDK)
 
+#### Marshmallow
+Running mojo on Marshmallow might raise an Exception `"Unable to find fifo"`. As
+a temporary solution, you can go to `Settings` -> `Apps` -> `Mojo Shell (dev)`
+-> `Permissions` and allow for `Storage`.
+See this [bug](https://github.com/domokit/mojo/issues/500) for more information.

 ### Goma (Googlers only)
 
 If you're a Googler, you can use Goma, a distributed compiler service for
 open-source projects such as Chrome and Android. If Goma is installed in the
 default location (~/goma), it will work out-of-the-box with the `mojob.py gn`,
 `mojob.py build` workflow described above.
 
 You can also manually add:
 ```
 use_goma = true
