How to install Syntaxhighlighter plugin for CKeditor on drupal 7?

Question

Drupal

Tell me how to install the plugin ckeditor.com/addon/syntaxhighlight for ckeditor.
I tried a bunch of options, but the {code} button did not appear. At the same time, in the list of plugins in the ckeditor setting, syntaxhighlight is displayed and the checkbox is checked.
In fact, I thought that having built myself ckeditor.com/builder ckeditor with the necessary plugins, I will install it once and forget it, but the additional plugins in the assembly I compiled do not work.
According to this dock docs.ckeditor.com/#!/guide/dev_installation is also not clear, well, I downloaded, copied, opened http:///ckeditor/samples/index.html and what? in the modules, then ckeditor did not appear from this.
Please explain how to do it.
PS I'm a noob in Drupal

Answer 1

Nikit Khaner Have you tried any of these instructions yourself? Firstly, they are all different, Secondly, the third link. I tried the instructions on the first link even before I came here with a question. I tried again, but the button did not appear.

Answer 2

here using the 3rd link https://www.drupal.org/sandbox/eduardoa/2157351 - enabled the plugin automatically, without problems on pure Drupal 7 + CKeditor.
Because this module is in the sandbox (under development), then you can’t just download it, you need to use git clone, if you can’t, I can send the archive privately.
ps Without this module also included using articles, there were no particular problems...
