-This repository holds the BlackBerry 10 port of Python-3.2.2.
-
-Our intent with this repository is:
-  1. Fulfill any license requirements by publishing any of our source code changes
-  2. To enable the larger community to build their own binaries which will run on BlackBerry 10 / PlayBook devices
-  3. To prepare and formalize our patch-set, in preparation for a push to the upstream Python.org repository.  Community assistance with this effort will be greatly appreciated, as internal commitments have most RIM employees tied up right now :)
-
-Build notes
-  1. Install BlackBerry 10 NDK tools and make sure environment variables are set up
-  2. Seems we need a case-sensitive build environment (partition accordingly on OSX, or create a DMG to build in)
-  3. May need to install Mercurial (Hg)
-  4. May need an existing host-native python installation
+## BlackBerry 10 Python port
+
+### Current status
+
+* Python 3.2.2 from BlackBerry building and working fine in the [Berrymuch](https://github.com/berryamin/berrymuch) prefix
+
+### Roadmap
+
+* Adapt the patchset for Python 3.4
+* Bundle into Berrymuch
+
+### Development
+
+#### Cross-compilation for ARM
+
+* Get an OS supported by the BlackBerry Native SDK (we recommend [32-bit Ubuntu 16.04](http://releases.ubuntu.com/16.04/ubuntu-16.04.6-desktop-i386.iso))
+* Install the [BlackBerry Native SDK](https://developer.blackberry.com/native/download/)
+* Install a few other packages:
+  ```
+  sudo apt install mercurial python
+  ```
+* Clone this repository and run:
+  ```
+  source ~/path/to/bbndk/bbndk_env.sh
+  cd Python-3
+  ./host.build
+  ./nto-armv7.build
+  ```
+
+#### Running on Berrymuch
+
+* Package it up:
+  ```
+  cd nto-armv7/accounts/1000/shared/documents/clitools
+  zip -yr python-3.2.zip .
+  ```
+* Transfer the package to your Berrymuch device and install with `pbpkgadd`
+* Add to your `~/.profile`:
+  ```
+  export PYTHONPATH="/accounts/1000/shared/documents/clitools/lib/python3.2:/accounts/1000/shared/documents/clitools/lib/python3.2/lib-dynload"
+  ```
+* Enjoy
