+human-readable and easy for version control systems to manage.
 
 The ESCN (exported scene) file format is identical to the TSCN file format, but
 is used to indicate to Godot that the file has been exported from another
 program and should not be edited by the user from within Godot.
+Unlike SCN and TSCN files, during import, ESCN files are compiled to binary
+SCN files stored inside the ``.import/`` folder.
+This reduces the data size and speeds up loading, as binary formats are faster
