 Facter is a command-line tool that gathers basic facts about nodes (systems)
 such as hardware details, network settings, OS type and version, and more.
 These facts are made available as variables in your Puppet manifests and can be

 ## Requirements
-* Ruby 2.5+

+* Ruby 2.6+
 * FFI (for facts like `mountpoints` which are resolved using C API calls)
 
 ## Basic concepts
+
 The project has three main parts, the framework, facts and resolvers.
 In the framework we implement functionality that is agnostic of specific facts like parsing user input, formatting output, etc.

 The implementation can be validated locally by running `bundle exec rake check`.
 
 ## Goals - fast, easy, compatible
+
 * Gain performance similar to the C++ version of Facter. We plan to achieve this goal by gathering multiple facts with only one call and by using the faster Win32 API rather than WMI for the Windows implementation.
 * Facilitate community contribution. At the moment, C++ presents a possible impediment for community contributions.
 * Enable native integration with other Ruby-based projects such as Bolt and puppet.
 * Enable native integration for custom facts.
 * Provide 100% compatibility with C++ Facter (drop-in replacement).
