+Quick Start
+===========
+
+**Prerequisites** for building libgit2:
+
+1. [CMake](https://cmake.org/), and is recommended to be installed into
+ your `PATH`.
+2. [Python](https://www.python.org) is used by our test framework, and
+ should be installed into your `PATH`.
+3. C compiler: libgit2 is C90 and should compile on most compilers.
+ * Windows: Visual Studio is recommended
+ * Mac: Xcode is recommended
+ * Unix: gcc or clang is recommended.
+
+**Build**
+
+1. Create a build directory beneath the libgit2 source directory, and change
+ into it: `mkdir build && cd build`
+2. Create the cmake build environment: `cmake ..`
+3. Build libgit2: `cmake --build .`
+
+Trouble with these steps? Read `TROUBLESHOOTING.md`. More detailed build
+guidance is available below.
