+Package xdg provides an implementation of the XDG Base Directory Specification.
+The specification defines a set of standard paths for storing application files
+including data and configuration files. For portability and flexibility reasons,
+applications should use the XDG defined locations instead of hardcoding paths.
+The package also includes the locations of well known user directories.
+
+The current implementation supports most flavors of Unix, Windows, Mac OS and Plan 9.
+
+	For more information regarding the XDG Base Directory Specification see:
+	https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html
+
+	For more information regarding the XDG user directories see:
+	https://wiki.archlinux.org/index.php/XDG_user_directories
+
+	For more information regarding the Windows Known Folders see:
+	https://docs.microsoft.com/en-us/windows/win32/shell/known-folders
+
+Usage
+
+XDG Base Directory
+	package main
+
+	import (
+		"log"
+
+		"github.com/adrg/xdg"
+	)
+
+	func main() {
+		// XDG Base Directory paths.
+		log.Println("Home data directory:", xdg.DataHome)
+		log.Println("Data directories:", xdg.DataDirs)
+		log.Println("Home config directory:", xdg.ConfigHome)
+		log.Println("Config directories:", xdg.ConfigDirs)
+		log.Println("Home state directory:", xdg.StateHome)
+		log.Println("Cache directory:", xdg.CacheHome)
+		log.Println("Runtime directory:", xdg.RuntimeDir)
+
+		// Other common directories.
+		log.Println("Home directory:", xdg.Home)
+		log.Println("Application directories:", xdg.ApplicationDirs)
+		log.Println("Font directories:", xdg.FontDirs)
+
+		// Obtain a suitable location for application config files.
+		// ConfigFile takes one parameter which must contain the name of the file,
+		// but it can also contain a set of parent directories. If the directories
+		// don't exist, they will be created relative to the base config directory.
+		configFilePath, err := xdg.ConfigFile("appname/config.yaml")
+		if err != nil {
+			log.Fatal(err)
+		}
+		log.Println("Save the config file at:", configFilePath)
+
+		// For other types of application files use:
+		// xdg.DataFile()
+		// xdg.StateFile()
+		// xdg.CacheFile()
+		// xdg.RuntimeFile()
+
+		// Finding application config files.
+		// SearchConfigFile takes one parameter which must contain the name of
+		// the file, but it can also contain a set of parent directories relative
+		// to the config search paths (xdg.ConfigHome and xdg.ConfigDirs).
+		configFilePath, err = xdg.SearchConfigFile("appname/config.yaml")
+		if err != nil {
+			log.Fatal(err)
+		}
+		log.Println("Config file was found at:", configFilePath)
+
+		// For other types of application files use:
+		// xdg.SearchDataFile()
+		// xdg.SearchStateFile()
+		// xdg.SearchCacheFile()
+		// xdg.SearchRuntimeFile()
+	}
+
+XDG user directories
+	package main
