 # pyjacklib
+
+Python bindings for `libjack` using [ctypes], which allow you to write JACK
+client applications in Python.
+
+The library provides a low-level, almost unaltered mapping of the `libjack`
+[C API], plus a few additional convenience functions.
+
+
+**Note:** **pyjacklib** *as a stand-alone project is in an early beta-stage and
+the API may still change slightly before a 1.0 release. You have been warned!*
+
+
+## Dependencies
+
+To use the library, your system needs to have the following installed at
+run-time:
+
+* The [JACK] library
+* A Python 3 implementation, which supports `ctypes`
+
+To build and install the library you need:
+
+* [setuptools]
+* (optional) [pip]
+
+
+## Building and Installing
+
+You can download and install **pyjacklib** directly from PyPI using `pip`:
+
+```con

+and run the following from inside the unpacked source directory resp. the root
+of your checkout:
