+Data paths
+==========
+
+Path separators
+---------------
+
+For the sake of supporting as many platforms as possible, Godot only
+accepts unix style path separators (``/``). These work everywhere,
+including Windows.
+
+A path like: ``C:\Projects`` will become ``C:/Projects``.
+
+Resource path
+-------------
+
+As mentioned before. Godot considers that a project exists at any
+given folder that contains an "project.godot" text file, even if such
+file is empty.
+
+Accessing project files can be done by opening any path with ``res://``
+as a base. For example, a texture located in the root of the project
+folder may be opened from the following path: ``res://sometexture.png``.
+
+Userdata path (persistent data)
+-------------------------------
+
+While the project is running, it is a very common scenario that the
+resource path will be read-only, due to it being inside a package,
+self contained executable, or system wide install location.
+
+Storing persistent files in such scenarios should be done by using the
+``user://`` prefix, for example: ``user://gamesave.txt``.
+
+In some devices (for example, mobile ad consoles) this path is unique
+for the app. Under desktop operating systems, the engine uses the
+typical ``~/.local/share/godot/app_userdata/Name`` (check the project
+name under the settings) in macOS and Linux, and ``APPDATA/Name``
+for Windows.
