-If you are familiar with TIFF, you can verify that there's no XMP tag in the
-TIFF file, but the Python XMP Toolkit takes advantage of the TIFF header
-structure to populate an XMP packet for you.  If you were working with a JPEG
-file with Exif metadata, that information would be included in the XMP packet 
-as well.  Now you can append the XMP packet in a UUIDBox.  In order to do this,
-though, you have to know the UUID that signifies XMP data.::
-
-    >>> import uuid
-    >>> xmp_uuid = uuid.UUID('be7acfcb-97a9-42e8-9c71-999491e3afac')
-    >>> box = glymur.jp2box.UUIDBox(xmp_uuid, str(xmp).encode())

-You can also build up XMP metadata from scratch.  For instance, if we try to
-wrap `goodstuff.j2k` again::
-
-    >>> import glymur
-    >>> j2kfile = glymur.data.goodstuff()
-    >>> j2k = glymur.Jp2k(j2kfile)
-    >>> jp2 = j2k.wrap("goodstuff.jp2")
-
-Now build up the metadata piece-by-piece.  It would help to have the XMP 
-standard close at hand::
-
-    >>> from libxmp import XMPMeta
-    >>> from libxmp.consts import XMP_NS_TIFF as NS_TIFF
-    >>> from libxmp.consts import XMP_NS_DC as NS_DC
-    >>> xmp = XMPMeta()

-    >>> xmp.set_property(NS_TIFF, "ImageWidth", str(ihdr.width))
-    >>> xmp.set_property(NS_TIFF, "ImageHeight", str(ihdr.height))
-    >>> xmp.set_property(NS_TIFF, "BitsPerSample", '3')
-    >>> xmp.set_property(NS_DC, "Title", u'Stürm und Drang')
-    >>> xmp.set_property(NS_DC, "Creator", 'Glymur')
-
-We can then append the XMP in a UUID box just as before::

 **Glymur** is an interface to the OpenJPEG library

+JPEG 2000 images is currently limited to images that can fit in memory
-**Glymur** can read images using OpenJPEG library versions as far back as 1.3,
-but it is strongly recommended to use version 2.1.0, which is the most recently 
-released version of OpenJPEG at this time.
 
-In regards to metadata, most JP2 boxes are properly interpreted.
+Of particular focus is retrieval of metadata.  Reading Exif UUIDs is supported,

+some very limited support for reading JPX metadata.  For instance,
+**asoc** and **labl** boxes are recognized, so GMLJP2 metadata can

+Glymur works on Python 2.6, 2.7, 3.3, and 3.4.
-you should use the 0.5 series of Glymur.
 
-For more information about OpenJPEG, please consult http://www.openjpeg.org.
+OpenJPEG Installation
+=====================
+Glymur will read JPEG 2000 images with versions 1.3, 1.4, 1.5, 2.0, and 2.1 of
+OpenJPEG.  Writing images is only supported with the 1.5 or better, however,
+and version 2.1 is strongly recommended.  For more information about OpenJPEG,
+please consult http://www.openjpeg.org.
+
+If you use MacPorts or if you have a sufficiently recent version of
+Linux, your package manager should already provide you with a version of
+OpenJPEG 1.X which glymur can already use.  If your platform is windows,
+I suggest using the windows installers provided to you by the OpenJPEG
+folks at https://code.google.com/p/openjpeg/downloads/list .
 
 Glymur Installation
 ===================
 You can retrieve the source for Glymur from either of
 
     * https://pypi.python.org/pypi/Glymur/ (stable releases)
-    * http://github.com/quintusdias/glymur (bleeding edge, use the devel branch)
+    * http://github.com/quintusdias/glymur (bleeding edge)
 
 but you should also be able to install Glymur via pip ::
 
     $ pip install glymur
 
-In addition to the package, this also gives you a command line script
+This will install the **jp2dump** script that can be used from the unix command
-**jp2dump** that can be used from the command line line to print JPEG 2000
+line, so you should adjust your **$PATH**
-metadata.
+to take advantage of it.  For example, if you install with pip's
+`--user` option on linux ::
+
+    $ export PATH=$HOME/.local/bin:$PATH
