 The `aosp` wrapper doesn't work well with setting up environments, but with
 some bash magic, this can be side stepped with short little scripts.  See

+[Docker Compose][]
+------
+
+A [Docker Compose][] file is provided in the root of this repository, you can tweak it as need be:
+
+```yaml
+version: "2"
+
+services:
+  aosp:
+    image: kylemanna/aosp:6.0-marshmallow
+    volumes:
+      - /tmp/ccache:/ccache
+      - ~/aosp:/aosp
+```
+Example run: `docker-compose run --rm aosp repo sync -j4` -- your android build directory will be in `~/aosp`.
+
+Issues
+------
+
+There are some known issues with using Docker Toolbox on macOS and current
+virtualization technologies resulting in unusual user ID assignments and very
+poor performing virtualization file sharing implementations with things like
+VirtualBox.  It's recommended to run this image completely in a virtual machine
+with enough space to fit the entire build (80GB+) as opposed to mapping the
+build to the local macOS file system via VirtualBox or similar.
