I tried your method - the name zip file that got downloaded to my computer from the above link is: "electrolinux-moodle-ckeditor-03812af
I then extracted the zip file and I could see the following files in this folder:
ckeditor, lang, .gitignore,lib.php, module.js,reademe,settings.php and todo
I then copied all the above files to moodle/lib/editor/ckeditor
I am using binarious theme so as per your above suggestion I have added this line: $CFG->texteditors='ckeditor,tinymce,htmlarea';
at the bottom of the config.php file in the binarious theme folder.
I then logged into my moodle site and clicked notification tab - there is no setting shown.
On manage text editors, I dont see the ckeditor.
Not sure why??
