-sane nested dictionaries and lists
-
 *sanest* is a python library that makes it easy to work with nested
 dictionaries and lists, such as those commonly used in json formats,
 without losing your sanity.
 
-this is a work-in-progress and you should not use it (for now).
-
-
-todo and ideas
-==============
-
-note: this is just a braindump, not a check list. some ideas may not
-be good ideas after all and may never make it into this library.
-
-* nested walk helpers dict.walk() and list.walk()
-
-* configurability
-
-  * maybe factory helper that produces two custom classes?
-  * e.g. mydict, mylist = sanest.make_contains(options=would, go=here)
-  * requires major overhaul
-
-* public api for read-only structures?
-
-  * construct-only
-  * sanest.dict.readonly()
-  * what about mixing?
-
-* maybe list.contains() with type= arg that checks provided value
-  while also checking containment
+* Documentation: https://sanest.readthedocs.io/
 
-* typed list.__contains__
+* Python Package Index (PyPI): https://pypi.python.org/pypi/sanest/
 
-* add a .clean(deep=True) helper (needs better name) to remove None
-  values from a (nested) dict
