Entered the theme review theme on make.wordpress.org. Today a lot of software was installed:

• Virtualbox (for a linux sandbox for WordPress)
• Installed the recommended bugtragging plugins in the sandbox.

Then I read the extensive documentation on coding standards, and the things a theme reviewer should look at.

The codesniffer gave some problems. The recipe found here worked.  The documentation in a zip-file on Slack missed many practical details. And so did the page on Github with the codesniffer code.

First phpcs was installed via apt-get. The next steps are contained in this shell history dump:

2010  phpcs --standard=WordPress wp-config.php
 2011  pear
