Describe the bug

Two main points:

https://www.cogentcore.org/core/setup/install

The <code> </code> blocks are not directly highlight-able (with brave browser on amd64 linux) which makes it basically impossible to copy only the installation command itself for cogentcore.

The only easy way to do it to highlight the whole line and do ctrl + C ; paste into an editor, and then copy the command to the terminal. Or manually type the whole thing.

it would be preferable if the installation command (or generally code blocks) had the behavior of single click copy

Additionally, the setup documentation assumes that you have GOPATH set correctly and that your GOBIN was already added to your PATH ; but this should be made explicit and not just assumed as it might confuse people.

core setup may be easy enough to remember or run, but it actually did not work for me on archlinux with my specific hardware, to install all the correct dependencies (#1223).

I recommend that the cogentcore/core runtime dependencies (installed by core setup) be listed somewhere in the installation documentation - even if this information is not useful to most people.

If cogentcore was packaged and installed as a package by the package manager on linux, installing it's runtime dependencies should be handled by the package manager. And it's deps should be installed as dependencies of cogentcore and not explicitly.

However, I assume the exact dependencies vary based on the hardware & os ; and core setup is supposed to detect this. That might be challenging to handle by the package manager automatically. It might work best with different flavors (so to speak) of the package which are intended for specific hardware and which include the specific runtime deps used by cogentcore for that hardware.

Still, i suggest informing the user of the dependencies for different hardware and operating systems, even if this is on a different page of documentation from the setup installation page.
