=== Skins

You can select third-party skins placed in assets/ckeditor-contrib/skins directory.

== Migration notes

This plugin stores contents in HTML format and renders as is. If you have old contents, these look weird.

You can use {redmine_per_project_formatting}[https://github.com/a-ono/redmine_per_project_formatting] plugin for backward compatibility or execute redmine_ckeditor:migrate task for migrating old text to HTML. rake redmine_ckeditor:migrate RAILS_ENV=production FROM=textile TO=html You can also use PROJECT parameter to migrate only specific projets rake redmine_ckeditor:migrate RAILS_ENV=production PROJECT=project_identifier1,project_identifier2 FROM=textile TO=html This task requires to {install Pandoc}[http://johnmacfarlane.net/pandoc/installing.html].
