 :beer: If you are using OS X and [Homebrew](http://brew.sh), just type `brew tap nlohmann/json` and `brew install nlohmann_json` and you're set. If you want the bleeding edge rather than the latest release, use `brew install nlohmann_json --HEAD`.
 
+If you are using the Meson Build System, then add a file called `nlohmann_json.wrap` to a file to your `subprojects` directory with the following 4 lines:
+
+```
+[wrap-git]
+directory=nlohmann_json
+url=https://github.com/nlohmann/json.git
+revision=head
+```
+
+You can then create a reference to it in your `meson.build` file by adding the line:
+
+```
+nlohmann_json_sp = subproject('nlohmann_json')
+```
+
+Here's an example of an executable called `awesomeness` that uses this library through the reference created above.
+
+```
+executable('awesomeness',
+  'awesomeness.cpp',
+  dependencies: nlohmann_json_sp.get_variable('nlohmann_json_dep')
+)
+```

 :warning: [Version 3.0.0](https://github.com/nlohmann/json/wiki/Road-toward-3.0.0) is currently under development. Branch `develop` is used for the ongoing work and is probably **unstable**. Please use the `master` branch for the last stable version 2.1.1.
