 # Finding your way
 This is an introduction to the mathplot repository; what's in each directory and why they are there.
 
-First off, the library is header-only, which means that you don't need to compile it to include it in your programs. You just `#include` the relevant headers in your own `.cpp` files. All the header files that you need to include are in **mathplot/morph**.

 At the time of writing, if you clone mathplot, change directory into its root and type `ls`, then you'll see something like this:

 The files in the root directory include some markdown/readme files (*.md), some cmake configuration files (CMakeLists.txt, cmake_cmd_windows.txt, CMakeSettings.seb.json), the license file, a valgrind suppression file for debugging and a number of glsl files that probably belong elsewhere.

-Most of mathplot is in the base namespace `mplot` and their files are at the base of **mplot/**. This is regardless of whether they are code for drawing visualizations or core maths code. Most classes are in a single `.h` header file with the same name as the class, although there are a few exceptions (such as **Random.h**, which contains several classes including ``morph::RandUniform`` and ``morph::RandNormal``).

 Files called `XxxVisual.h` are classes that derive from `mplot::VisualModel`. This means that they are models that you can incorporate into your `mplot::Visual` scene. For example, `TriaxesVisual.h` is for drawing a 3D axis into which you can place a 3D scatter or quiver plot. `ColourbarVisual.h` helps you to draw a colour bar legend to display alongside one of your graphs.
