-Introduction
-------------
-
-The parameters interpreted by the jerasure plugin are:
-
-::
- 
-  ceph osd erasure-code-profile set myprofile \
-     directory=<dir>         \ # plugin directory absolute path
-     plugin=jerasure         \ # plugin name (only jerasure)
-     k=<k>                   \ # data chunks (default 2)
-     m=<m>                   \ # coding chunks (default 2)
-     technique=<technique>   \ # coding technique
-
-The coding techniques can be chosen among *reed_sol_van*,
-*reed_sol_r6_op*, *cauchy_orig*, *cauchy_good*, *liberation*,
-*blaum_roth* and *liber8tion*.
-
-The *src/erasure-code/jerasure* directory contains the
-implementation. It is a wrapper around the code found at
-`https://github.com/ceph/jerasure <https://github.com/ceph/jerasure>`_
-and `https://github.com/ceph/gf-complete
-<https://github.com/ceph/gf-complete>`_ , pinned to the latest stable
-version in *.gitmodules*. These repositories are copies of the
-upstream repositories `http://jerasure.org/jerasure/jerasure
-<http://jerasure.org/jerasure/jerasure>`_ and
-`http://jerasure.org/jerasure/gf-complete
-<http://jerasure.org/jerasure/gf-complete>`_ . The difference
-between the two, if any, should match pull requests against upstream.
