-📣 **nameparser 2.0 is in design** — a new immutable core API, with full
-compatibility for existing code through 2.x. Read the `design RFC
-<https://github.com/derek73/python-nameparser/pull/285>`__ and share
-feedback on `the discussion issue
-<https://github.com/derek73/python-nameparser/issues/284>`__.
-
-A simple Python (3.10+) module for parsing human names into their
-individual components.
-
-* hn.title
-* hn.first
-* hn.middle
-* hn.last
-* hn.suffix
-* hn.nickname
-* hn.maiden
-* hn.surnames *(middle + last)*
-* hn.given_names *(first + middle)*
-* hn.initials *(first initial of each name part)*
-* hn.last_base *(last, minus any prefixes)*
-* hn.last_prefixes *(leading last-name particles, e.g. "van der")*
-
-Supported Name Structures
-~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The supported name structure is generally "Title First Middle Last Suffix", where all pieces 
-are optional. Comma-separated format like "Last, First" is also supported.
-
-1. Title Firstname "Nickname" Middle Middle Lastname Suffix
-2. Lastname [Suffix], Title Firstname (Nickname) Middle Middle[,] Suffix [, Suffix]
-3. Title Firstname M Lastname [Suffix], Suffix [Suffix] [, Suffix]
-
-How It Works
-~~~~~~~~~~~~
-
-The parser works in two layers.
-
-A **vocabulary layer** recognizes name pieces by what they are, using
-configurable sets of known words: titles ("Dr."), suffixes ("III", "PhD"),
-last-name prefixes ("de la"), conjunctions ("y", "&"), and delimited
-nicknames ("Doc"). Titles and conjunctions chain together to handle complex
-titles like "Asst Secretary of State"; prefixes join forward so "de la Vega"
-stays one last name. This layer doesn't care where in the string a word
-appears — and it's the layer you customize, by adding or removing entries
-in the sets to fit your dataset.
-
-A **positional layer** then assigns everything the vocabulary layer didn't
-claim, based purely on where it sits: the first unclaimed word is the first
-name, the last one is the last name, and anything between them is a middle
-name. There is no semantic understanding — "Dr" is a title when it comes
-before a name and a suffix when it comes after ("pre-nominal" and
-"post-nominal" would probably be better names) — and no attempt to correct
-mistakes in the input.
-
-It attempts the best guess that can be made with a simple, deterministic,
-rule-based approach — no statistical models or machine learning; the same
-input always parses the same way. The positional layer assumes Western name
-order (given name first), so the main use case is English and other
-languages that share that structure. It can also try to correct the
-capitalization of names that are all upper- or lowercase. It's not perfect,
-but it gets you pretty far.
+nameparser parses human names into seven fields — title, given, middle,
+family, suffix, nickname, maiden. Results are immutable, configuration is
+composable, and locale packs are opt-in.
 
 Installation

@@ -72,95 +14,55 @@ Installation
 
   pip install nameparser
 
-If you want to try out the latest code from GitHub you can
-install with pip using the command below.
-
-``pip install -e git+https://github.com/derek73/python-nameparser.git``
-
-If you need to handle lists of names, check out
-`namesparser <https://github.com/gwu-libraries/namesparser>`_, a
-compliment to this module that handles multiple names in a string.
-
+Requires Python 3.11+.
 
 Quick Start Example
--------------------
-
-::
-
-    >>> from nameparser import HumanName
-    >>> name = HumanName("Dr. Juan Q. Xavier de la Vega III (Doc Vega)")
-    >>> name 
-    <HumanName : [
-        title: 'Dr.'
-        first: 'Juan'
-        middle: 'Q. Xavier'
-        last: 'de la Vega'
-        suffix: 'III'
-        nickname: 'Doc Vega'
-        maiden: ''
-    ]>
-    >>> name.last
-    'de la Vega'
-    >>> name.as_dict()
-    {'title': 'Dr.', 'first': 'Juan', 'middle': 'Q. Xavier', 'last': 'de la Vega', 'suffix': 'III', 'nickname': 'Doc Vega', 'maiden': ''}
-    >>> str(name)
-    'Dr. Juan Q. Xavier de la Vega III (Doc Vega)'
-    >>> name.string_format = "{first} {last}"
-    >>> str(name)
-    'Juan de la Vega'
-
-
-Because the positional layer has no semantic understanding, position is
-everything:
-
-::
-
-    >>> name = HumanName("1 & 2, 3 4 5, Mr.")
-    >>> name 
-    <HumanName : [
-        title: ''
-        first: '3'
-        middle: '4 5'
-        last: '1 & 2'
-        suffix: 'Mr.'
-        nickname: ''
-        maiden: ''
-    ]>
-
-Customization
--------------
-
-Your project may need some adjustment for your dataset. Most customization
-is vocabulary — `customizing the configured pre-defined sets`_ of titles,
-prefixes, etc. that the vocabulary layer matches against. You can also do
-your own pre- or post-processing, or subclass the `HumanName` class for
-deeper changes. See the `full documentation`_ for more information.

+Coming from 1.x
+----------------
+
+``HumanName`` and ``CONSTANTS`` keep working in 2.0 — same imports, same
+attributes, same mutation API. What 2.0 removes is the batch of
+deprecations 1.3 and 1.4 announced, so if your test suite runs clean on
+1.4 under ``python -W error::DeprecationWarning``, you are nearly done.
+Two things that check will not catch: four removals 1.4 never warned
+about (three raise on contact, the fourth only warns), and one that
+changes results silently — ``name == "John Smith"`` is now ``False``.
+`Migrating from HumanName <https://nameparser.readthedocs.io/en/latest/migrate.html>`__
+covers both, and translates a v1 customization into the new API whenever
+that's convenient for you.
+
+See the `release log <https://nameparser.readthedocs.io/en/latest/release_log.html>`__
+for the full list of changes in the 2.0 series.
