-Python bindings for Mapnik.

 ## Installation
 
-Eventually we hope that many people will simply be able to `pip install mapnik` in order to get prebuilt binaries,
-this currently does not work though. So for now here are the instructions
-
-### Create a virtual environment
-
-It is highly suggested that you have [a python virtualenv](http://docs.python-guide.org/en/latest/dev/virtualenvs/) when developing
-on mapnik.
-
-### Building from Mason
-
-If you do not have mapnik built from source and simply wish to develop from the latest version in [mapnik master branch](https://github.com/mapnik/mapnik) you can setup your environment with a mason build. In order to trigger a mason build prior to building you must set the `MASON_BUILD` environment variable.
-
-```bash
-export MASON_BUILD=true
-```
-
-After this is done simply follow the directions as per a source build.
-
 ### Building from Source
 
-Assuming that you built your own mapnik from source, and you have run `make install`. Set any compiler or linking environment variables as necessary so that your installation of mapnik is found. Next simply run one of the two methods:
-
-```
-python setup.py develop
-```
-
-If you are currently developing on mapnik-python and wish to change the code in place and immediately have python changes reflected in your environment.
-
-
-```
-python setup.py install
-```
-
-If you wish to just install the package.
-
-```
-python setup.py develop --uninstall
-```
-
-Will de-activate the development install by removing the `python-mapnik` entry from `site-packages/easy-install.pth`.
-
-
-If you need Pycairo, make sure that PYCAIRO is set to true in your environment or run:
+Make sure 'mapnik-config' is present and accessible via $PATH env variable 
 
 ```
-PYCAIRO=true python setup.py develop
+pip install . -v 
 ```
 
-### Building against Mapnik 3.0.x
-
-The `master` branch is no longer compatible with `3.0.x` series of Mapnik. To build against Mapnik 3.0.x, use [`v3.0.x`](https://github.com/mapnik/python-mapnik/tree/v3.0.x) branch.
-
 ## Testing
 
 Once you have installed you can test the package by running:
 
 ```
-git submodule update --init
-python setup.py test
-```
-
-The test data in `./test/data` and `./test/data-visual` are standalone modules. If you need to update them see https://github.com/mapnik/mapnik/blob/master/docs/contributing.md#testing
-
-
-### Troubleshooting
-
-If you hit an error like:
-
-```
-Fatal Python error: PyThreadState_Get: no current thread
-Abort trap: 6
+pytest test/python_tests/
 ```
 
-That means you likely have built python-mapnik linked against a different python version than what you are running. To solve this try running:
-
-```
-/usr/bin/python <your script.py>
-```
-
-If you hit an error like the following when building with mason:
-
-```
-EnvironmentError: 
-Missing boost_python boost library, try to add its name with BOOST_PYTHON_LIB environment var.
-```
-
-Try to set `export BOOST_PYTHON_LIB=boost_python` before build.
-Also, if `boost_thread` or `boost_system` is missing, do likewise:
-
-```
-export BOOST_SYSTEM_LIB=boost_system
-export BOOST_THREAD_LIB=boost_thread
-```
 
-If you still hit a problem create an issue and we'll try to help.
