 Build steps:
 
 1. Build [libzmq](https://github.com/zeromq/libzmq) via cmake. This does an out of source build and installs the build files
-   - download and unzip the lib, cd to directory
-   - mkdir build
-   - cd build
-   - cmake ..
-   - sudo make -j4 install
+   - `git clone https://github.com/zeromq/libzmq.git`
+   - `cd libzmq`
+   - `mkdir build`
+   - `cd build`
+   - `cmake ..`
+   - `sudo make -j4 install`

-   - git clone https://github.com/Microsoft/vcpkg.git
