How do I install the Source Pause Tool?

I dont know how to download it

Also, join in SourceRuns Discord, because nobody read SR forum: https://discord.gg/sourceruns

>200 people a day do (hard to tell because ad blockers), so having answers here is valuable - especially because nothing in Discord can be found through search engines.
