 ## General description.
 
 This is a library for computing homotopy continuation of a given root of one
-dimensional sections of bivariate complex polynomials (of degree greater than 2).
+dimensional sections of bivariate complex polynomials.
 The output is a piecewise linear aproximation of the path followed by the root,
 with the property that there is a tubular neighborhood, with square transversal
 section, that contains the actual path, and there is a three times thicker tubular

 ## Usage:
 
 After installing the library, you can call it from any .cpp program by calling

+the `homotopyPath` or `homotopyPath_mp` functions. In the file tests/sirocco_test.cpp
