-""" This plugin offers more fine-grained control over exluded images and folders, similarly to how
-    it's handled on Android.
-
-    To ignore a folder or image put a .nomedia file next to it in its parent folder and put its name
-    into the file.
-    E.g.:
-        content of folder:
-            IMG_3425.JPG, IMG_2426.JPG, IMG_2427.JPG, subfolder, .nomedia
-        content of .nomedia:
-            IMG_2426.JPG
-            IMG_2427.JPG
-            subfolder
-    will ignore all images but IMG_3425.JPG and the subfolder
-
-    Alternatively, if you put a .nomedia file into a folder and leave it blank (i.e. an empty file
-    called .nomedia in a folder containing images), this ignores the whole folder it's located in
-    (like on Android).
-
-    WARNING: When you have a pre-existing gallery from a previous run of sigal adding a new .nomedia
-    file will not remove the newly ignored images/albums from the existing gallery (only the entries
-    in the parent gallery pointing to it). They might still be reachable thereafter. Either remove
-    the whole gallery to be sure or remove the ignored files/folders inside the gallery to remove
-    them for good.
