+##### XDG Directories
+
+These functions return paths to user-specific directories for things like
+configuration, data, caches, executables, and the user's home directory. These
+functions follow the
+[XDG Base Directory Specification](https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html),
+and are implemented with the
+[`dirs`](https://docs.rs/dirs/latest/dirs/index.html) crate.
+
+- `cache_directory()` - The user-specific cache directory.
+- `config_directory()` - The user-specific configuration directory.
+- `config_local_directory()` - The local user-specific configuration directory.
+- `data_directory()` - The user-specific data directory.
+- `data_local_directory()` - The local user-specific data directory.
+- `executable_directory()` - The user-specific executable directory.
+- `home_directory()` - The user's home directory.
