+## XDG Variables
+
+| Var                | Default              |
+|--------------------|----------------------|
+| Executables        | `$HOME/.local/bin`   |
+| `$XDG_DATA_HOME`   | `$HOME/.local/share` |
+| `$XDG_STATE_HOME`  | `$HOME/.local/state` |
+| `$XDG_CONFIG_HOME` | `$HOME/.config`      |
+
+
+- `$XDG_DATA_HOME` defines the base directory relative to which user-specific data files should be stored. If `$XDG_DATA_HOME` is either not set or empty, a default equal to ` $HOME/.local/share` should be used.
+- `$XDG_CONFIG_HOME` defines the base directory relative to which user-specific configuration files should be stored. If `$XDG_CONFIG_HOME` is either not set or empty, a default equal to `$HOME/.config` should be used.
+- `$XDG_STATE_HOME` defines the base directory relative to which user-specific state files should be stored. If `$XDG_STATE_HOME` is either not set or empty, a default equal to `$HOME/.local/state` should be used.
+- The `$XDG_STATE_HOME` contains state data that should persist between (application) restarts, but that is not important or portable enough to the user that it should be stored in `$XDG_DATA_HOME`. It may contain:
+  - actions history (logs, history, recently used files, …)
+  - current state of the application that can be reused on a restart (view, layout, open files, undo history, …)
+- User-specific executable files may be stored in `$HOME/.local/bin`. Distributions should ensure this directory shows up in the UNIX `$PATH` environment variable, at an appropriate place.
+- `$XDG_DATA_DIRS` defines the preference-ordered set of base directories to search for data files in addition to the `$XDG_DATA_HOME` base directory. The directories in `$XDG_DATA_DIRS` should be seperated with a colon ':'.
