Chess By Blog

Chess By Blog has been tested on WordPress 2.0.4 to 3.0; it is not
supported for earlier versions.

Before installing, you should back up your WordPress blog,
particularly if you intend to use the persistent game feature since
this will make changes directly to your database. The changes should
only be limited to the body of the post which contains the chess
board, and I’m not aware of any issues with the code – but better safe
than sorry.

If you are upgrading, it is recommended that you first disable the
plugin, then remove the files in the old chess-by-blog
subdirectory. This is optional: however, due to the names of the
Javascript scripts created by the Google Web Toolkit, new files tend
to have different names and the old ones aren’t replaced – they just
take up disk space.

The top level contents of the zip folder look like this:

/chess-by-blog
+–readme.txt (this file!)
+–chess-by-blog.php
+–/chess-by-blog
+—-/themes
+—-(support files)
+–/src

The top level chess-by-blog directory should be copied to your WordPress
wp-content plugins directory. Optionally, unless you are building the
client side code yourself, you can delete the src directory.

You should now be able to activate the plugin from the WordPress
Plugins administration panel.
