I was following “Toolchain installation” and under the section [VSCode extensions] there is a link to Sway plugin.
I’m using Arch Linux and Code-OSS. Just by searching sway plugin under View > Extensions, I couldn’t find it. In order to be able to find it, I had to install AUR (en) - code-marketplace. Maybe it’s worth mentioning it in the instruction docs.
I would actually suggest extending documentation (where the code lines are) with tabs containing system based adjusted commands. Example: Chrome specific functionality | Selenium (here tabs are per language not per operating system).
