+Installation
+------------
+The package is supplied in dtx format and as a pre-extracted zip file,
+xecjk.tds.zip. The later is most convenient for most users: simply
+unzip this in your local texmf directory and run texhash to update the
+database of file locations. If you want to unpack the dtx yourself,
+running "xetex xeCJK.dtx" will extract the package whereas
+"xelatex xeCJK.dtx" will extract it and also typeset the documentation.
+
+The package requires LaTeX3 support as provided in the l3kernel and
+l3packages bundles and the fontspec package. All of these are available
+on CTAN as ready-to-install zip files. Suitable versions are available
+in the latest version of MiKTeX and TeX Live (updating the relevant
+packages online may be necessary).
+
+To compile the documentation without error, you will need some specific
+CJK scripts fonts (TrueType or OpenType).
