 [![Build Status](https://travis-ci.com/stribor14/Bezier-cpp.svg?branch=master)](https://travis-ci.com/stribor14/Bezier-cpp)
+![v0.2.0](https://img.shields.io/badge/version-0.2.0-blue.svg)
 [![Codacy Badge](https://api.codacy.com/project/badge/Grade/aceb46ce7de1407abd56cfc127dba5f1)](https://www.codacy.com/app/stribor14/Bezier-cpp?utm_source=github.com&utm_medium=referral&utm_content=stribor14/Bezier-cpp&utm_campaign=Badge_Grade)
 
 Fast and lightweight class for using the Bezier curves of any order in C++
 
 *Algorithm implementations are based on [A Primer on Bezier Curves](https://pomax.github.io/bezierinfo/) by Pomax*
 
 ## Key Features
-  - dynamic operations
-  - any order of curve
-  - optimized for real-time calculations
-
-## Implementeed methods
-  - get value, curvature, tangent and normal for parameter *t*
-  - get t from projection any point onto a curve
-  - get derivative curve
-  - split into two subcurves
-  - find extremes and bounding box
-  - find points of intersection with another curve
-  - elevate/lower order
-  - manipulate control points
-  - manipulate dot on curve (only for quadratic and cubic curves)
+  - Any number of control points
+  - Fast operations on curves
+  - Dynamic manipulation
+  - Composite Bezier curves (polycurves)
+
+## Implemented methods
+  - Get value, derivative, curvature, tangent and normal for parameter *t*
+  - Get t from projection any point onto a curve
+  - Get precise length for any part of curve
+  - Get a derivative curve (hodograph)
+  - Split into two subcurves
+  - Find curve roots and bounding box
+  - Find points of intersection with another curve
+  - Elevate/lower order
+  - Apply parametric and geometric continuities
+  - etc.

+    - [ ] Polycurve - oversee continuities between consecutive sub-curves
+    - [ ] Polycurve - propagation of sub-curve manipulation depending on continutiy
+    - [ ] More sophisticated example

 ## Dependencies
   - c++11
   - Eigen3
 
-*Add compile flag* `-march=native` *when compiling to use vectorization with Eigen.*
+## Instalation
+CMake *find_package()* compatible!
+```
+find_package(BezierCpp)
+target_link_libraries(target BezierCpp)
+```
+### System-wide installation
+```
+git clone https://github.com/stribor14/Bezier-cpp
+mkdir Bezicer-cpp/build
+cd Bezicer-cpp/build
+cmake ..
+make
+make install
+```
+### ROS
+- for use within a ROS workspace without the system-wide installation, clone the repo to src folder in you catkin workspace 
 
-## Example program
+## Example program __[OUTDATED]__ 
 A small Qt5 based program written as a playground for manipulating Bezier curves.
-### Usage
- - starts with two Bezier curves (with 4 and 5 control points respectively)
- - Zoom in/out: *__Ctrl + mouse wheel__*
- - Manipulate control point or point on curve: *__Left mouse buttom__*
- - Project mouse pointer on all curves and show tangent: *__Right mouse buttom__*
- - Split curve at mouse point: *__Middle mouse buttom__*
- - Raise order of the curve: *__Double left click__*
- - Lower order of the curve *__Double right click__*
- - Toggle bounding boxes and curve intersections: *__Double middle click__*
+- press *__H__* for a list of possible actions
