Local Documentation for Linux Editor

So I recently downloaded the beta version of the Linux Editor, installing it on my Ubuntu partition, however when I go into the the Help → Unity Manual or Help → Scripting Reference they don’t actually launch anything. I looked around in where the offline documentation would usually be for Windows except in my Ubuntu files but I couldn’t find anything.

So my question is, are there any offline documentation files for the Linux editor or are they just absent? If they are absent is there anyway to get a hold of the offline version, since I need an offline reference due to a trip I’m about to take and the spotty internet that I will have.

TL;DR: No, they aren’t included in the current (Unity 5.4) Linux build.

Logically, the files should be in /opt/Unity/Editor/Data/Documentation (if you compare the folder structure to that of other operating systems). But there is nothing there. In fact, I can’t find the documentation in any part of /opt/Unity which makes me believe they didn’t include it.

I was able to get a hold of offline documentation by contacting another Unity developer who used a different OS. They were able to create a ZIP of the documentation and send it to me.

In such cases, the documentation can be found in the following directories:

  • Windows: _C:\Program Files\Unity\Editor\Data\Documentation\en\ScriptReference\ _
  • MAC/OSX: /Applications/Unity/Unity.app/Contents/Documentation/en/ScriptReference/

Since I also had this question, I wanted to provide an updated (March 2020) answer.

The documentation is downloaded if the Documentation module is selected during install, which is the default. You can check by going to Unity Hub → Installs → Menu > Add Modules.

The downloaded files are installed to ~/Unity/Hub/Editor/<Editor version>/Editor/Data/Documentation/Documentation/en/. For example, the Script Reference for my install is at ~/Unity/Hub/Editor/2019.2.17f1/Editor/Data/Documentation/Documentation/en/ScriptReference/index.html

Alternatively, you can download the Documentation from Unity - Manual: Offline documentation .
