 Mutable History For Mercurial
 =============================
 
-This package supplies the ``evolve`` extension for Mercurial, which
-provides several commands to mutate history and deal with the
-resulting issues.
+Evolve Extension
+=================
+
+This package supplies the ``evolve`` extension for Mercurial,
 
-It also:
+**The full implementation of the changeset evolution concept is still in
+progress.**  Please subscribe to the `evolve-testers mailing list
+<https://www.mercurial-scm.org/mailman/listinfo/evolve-testers>`_ to stay up to
+date with changes.
+
+This extension:
 
-    - enables the "changeset obsolescence" feature of Mercurial
-    - issues several warning messages when trouble appears in your repository
+* enables the “changeset evolution” feature of Mercurial core,
 
-**This extension is experimental and not yet meant for production.**
+* provides a set of commands to mutate your history,
+
+* issues several warning messages when troubles from some mutable appears in
+  your repository,
 
-You can enable it by adding the line below to the ``extensions``
-section of your hgrc::
+* provides an ``hg evolve`` command to deal with such "troubles",
 
-    evolve = PATH/TO/evolve-main/hgext/evolve.py
+* improves performance of obsolescence marker exchanges and discovery during
+  push and pull.
+
+Documentation
+-------------
 
 We recommend reading the documentation first. An online version is
 available here:

+How to Install

+Using Pip
+---------
+
+You can install the latest evolution version usin pip::
+
+    $ pip install --user hg-evolve

+It is possible to enable a smaller subset of the extensions aimed at server
+serving repository. It skips the additions of the new commands and local UI
+messages that might add performance overheads. To use the server only
+extension, install the package and use::

 Please use the patchbomb extension to send email to mercurial devel. Please
 make sure to use the evolve-ext flag when doing so. You can use a command like

+    $ hg email --to [e-mail] --flag evolve-ext --rev '<your patches>'

 Please don't forget to update and run the tests when you fix a bug or
 add a feature. To run the tests, you need a working copy of Mercurial,
-say in $HGSRC:

 (evolve's stable and default branches correspond to Mercurial's stable
 and default branches. So to test evolve from default, you need
