 **OpenXR.rb** implements Ruby bindings for [OpenXR](https://www.khronos.org/openxr/)
 [1.0](https://www.khronos.org/registry/OpenXR/specs/1.0/html/xrspec.html),
 the open standard and cross-platform API for virtual reality (VR) and
 augmented reality (AR) hardware.
 
-Installation
-------------
-
-    $ gem install openxr
-
-Prerequisites
--------------
+## Prerequisites
 
 - [Ruby](https://www.ruby-lang.org/en/) 2.7+
   with [FFI](https://github.com/ffi/ffi/wiki)
 
 - [OpenXR SDK](https://github.com/KhronosGroup/OpenXR-SDK) 1.0.8+
 
-Examples
---------
+## Installation
+
+```bash
+$ gem install openxr
+```
+
+## Examples
 
-### Loading the library
+### Importing the library
 
-    require 'openxr'
+```ruby
+require 'openxr'
+```
 
 ### Listing extensions
 
-    OpenXR::Extension.each do |extension|
-      puts [extension.name, extension.version].join("\t")
-    end
+```ruby
+OpenXR::Extension.each do |extension|
+  puts [extension.name, extension.version].join("\t")
+end
+```
 
 ### Creating an instance
 
-    OpenXR::Instance.create($0) do |instance|
-      ...
-    end
+```ruby
+OpenXR::Instance.create($0) do |instance|
+  ...
+end
+```
 
-Development
------------
+## Development
 
 We recommend Debian 11 (aka [Bullseye](https://www.debian.org/releases/bullseye/))
 as a development environment. If you're on a Mac, you can run Debian in a
@@ -52,19 +55,22 @@ or [VirtualBox](https://www.virtualbox.org).
 
 Install the Debian packages for the OpenXR SDK's loader as follows:
 
-    $ apt install libopenxr-loader1
+```bash
+$ apt install libopenxr-loader1
+```
 
 That's the only required package, but find related packages of interest using:
 
-    $ apt search openxr
+```bash
+$ apt search openxr
+```
 
 In addition, you _will_ need an OpenXR runtime for your hardware. In the
 absence of suitable vendor-supplied runtimes, have a look at the open-source
 [Monado](https://monado.freedesktop.org) project which supports many common
 devices.
