+## Quick Start (with CMake)
+
+### Prerequisites
+
+- CMake 3.5 or newer
+- A C++14 compiler (Visual C++ 2015, GCC 5.0, Clang 3.4, or newer)
+- OpenSSL headers and libraries (optional, but recommended; on macOS, via Homebrew: `brew install openssl`)
+
+### Building
+
+```
+$ git clone -b master https://github.com/pocoproject/poco.git
+$ cd poco
+$ mkdir cmake-build
+$ cd cmake-build
+$ cmake .. && cmake --build .
+```
+
+You can also run:
+
+```
+$ sudo cmake --build . --target install
+```
+
+in the `cmake-build` directory to install POCO (default `/usr/local` on Linux or macOS).
+
+If you do not want to or cannot use CMake, POCO can also be built with Visual Studio
+(project and solution files included) or GNU Make.
+
+Please refer to the [documentation](https://pocoproject.org/docs) for more information.
+
+POCO can also be obtained via different [package managers](https://pocoproject.org/download.html).

+### POCO vs. Boost
+
 In regards to Boost, in spite of some functional overlapping,
 POCO is best thought of as a Boost complement (rather than replacement).
 Side-by-side use of Boost and POCO is a very common occurrence.
