-`JIGSAW` is an unstructured mesh generator and tessellation library; designed to generate high-quality triangulations and polyhedral decompositions of general planar, surface and volumetric domains. `JIGSAW` includes refinement-based algorithms for the construction of new meshes, optimisation-driven techniques for the improvement of existing grids, as well as routines to assemble (restricted) Delaunay tessellations, Voronoi complexes and Power diagrams.

 ### `Getting Started`
 
-The full `JIGSAW` src can be found in <a href="../master/src/">`../jigsaw/src/`</a>. It has been built using various `c++17` conforming versions of the `g++`, `clang++` and `msvc` compilers.
-
 `JIGSAW` is a `header-only` package - the single main `jigsaw.cpp` file simply `#include`'s the rest of the library directly. `JIGSAW` does not currently dependent on any external packages or libraries.
 
 `JIGSAW` consists of several pieces: `(a)` a set of command-line utilities that read and write mesh data from/to file, and `(b)` a shared library, accessible via a `c`-format `API`.
 
 ### `Using cmake`
 
-`JIGSAW` can be built using the <a href="https://cmake.org/">`cmake`</a> utility. To build, follow the steps below:
