 This library allows to parse an URDF file and create RBDyn structure from it. It is entirely ROS-free.

+Installing
+------
+
+## Ubuntu LTS (14.04, 16.04, 18.04): PPA
+
+Use the [multi-contact-unstable](https://launchpad.net/~pierre-gergondet+ppa/+archive/ubuntu/multi-contact-unstable) ppa:
+```bash
+sudo add-apt-repository ppa:pierre-gergondet+ppa/multi-contact-unstable
+sudo apt-get update
+sudo apt-get install librbdyn-dev librbdyn-doc python-rbdyn python3-rbdyn
+```
+
+## Manually build from source
+
+#### Dependencies
 
 - tinyxml2
 - Eigen (>= 3.0)
 - SpaceVecAlg (with Python bindings if needed)
 - RBDyn (with Python bindings if needed)
-- Cython (>= 0.25) (Python bindings)
+- Cython (>= 0.2) (Python bindings)
 - Eigen3ToPython (Python bindings)
 - Boost (unit tests)
+
+### Building
+
+```sh
+git clone --recursive https://github.com/jrl-umi3218/RBDyn
+cd RBDyn
+mkdir _build
+cd _build
+cmake [options] ..
+make && make intall
+```
+
+#### CMake options
+
+By default, the build will use the `python` and `pip` command to install the bindings for the default system version (this behaviour can be used to build the bindings in a given virtualenv). The following options allow to control this behaviour:
+
+ * `PYTHON_BINDING` Build the python binding (ON/OFF, default: ON)
+ * `PYTHON_BINDING_FORCE_PYTHON2`: use `python2` and `pip2` instead of `python` and `pip`
+ * `PYTHON_BINDING_FORCE_PYTHON3`: use `python3` and `pip3` instead of `python` and `pip`
+ * `PYTHON_BINDING_BUILD_PYTHON2_AND_PYTHON2`: builds two sets of bindings one with `python2` and `pip2`, the other with `python3` and `pip3`
+ * `DISABLE_TESTS` Disable unit tests building (ON/OFF, default: OFF)
