Steam
Installation
Windows
Go to the Steam website, download and install Steam.
Linux
Depending on your distribution and package manager, you need to run a different command in your terminal to install Steam.
WARNING
Recent versions of Ubuntu install the Snap version of Steam, and Steam developers recommend against it.
sudo apt install steam
Disable Remote Play
If you don't use this feature, you can disable it from the settings. It won't run in the background this way.
Configuring Proton (Linux only)
Proton is a tool forked from Wine and developed by Valve to run Windows games on operating systems using Linux. It acts as a compatibility layer and you can enable it from the Steam settings.
You can check out this guide made by GamingOnLinux to configure it.
Improve download speed (Linux only)
If Steam downloads are slower than normal, you can disable HTTP2 by running these commands inside a terminal:
echo "@nClientDownloadEnableHTTP2PlatformLinux 0" >> ~/.steam/steam/steam_dev.cfg
echo "@fDownloadRateImprovementToAddAnotherConnection 1.0" >> ~/.steam/steam/steam_dev.cfg
