What system to choose for documenting work processes in the company?

Question

HTML

The office has accumulated a lot of documents that describe all kinds of processes for working with clients, with the training of new employees. There are many standards for layout and programming.
The question arose of how to structure the whole thing and what system to choose for this?
The authorities think that it is convenient to deploy the wiki engine locally. I have an idea to create a private repository on gitHub and keep documentation there.
From the functionality, I would like to have code markup, insertion and execution of js code, convenient text design, it is desirable that the whole thing be in the cloud.
Are there any other options?

I’ve been using XWiki for the 3rd year

If it’s interesting, I can give you a link to download the customized distribution, now version 9.3.1 is already relevant, which has significantly advanced further in terms of convenience and capabilities. In principle, you can also run JS, but this is done through objects, i.e. rights are required, other supported scripts are run from the body of the page text. In my opinion, of all free wiki engines, it has the most convenient and user-friendly interface for the user, the widest possibilities, if something is missing, then a plugin is written or a plugin is installed, recently paid ones have begun to appear, but so far there are as many as 2 pcs.
Code markup:
extensions.xwiki.org/xwiki/bin/view/Extension/Code...
Convenient text entry:
extensions.xwiki.org/xwiki/bin/view/Extension/CKEd...
There is also the possibility of integration with OpenOffice
Local syntax:
extensions.xwiki.org/xwiki/bin/view/XWiki/XWikiSyntax
XWiki is a second generation wiki, written in Java, LGPL distribution license, features include blog, API tools, comments, LDAP authentication, page export to PDF. There is also the ability to program scripts (Velocity, Groovy, Python, Ruby and PHP) and support the syntax of popular wiki engines (Confluence, JSPWiki, Creole, MediaWiki, and TWiki). Used by many companies around the world. 25 interface languages, including Russian.

Answer 2

We use notion.so and are happy as flying elephants.

• The fact that it's SaaS may not fit; but at any time you can export the entire database of documents in Markdown format.
  
• After a certain amount of documents, you will have to switch to a tariff plan with payment of $8 per month for each user with editing rights. Anyone who does not need editing can be added as guests (without being included in the team), they will have read-only access and there can be as many as you like.
