How to setup/install/test latest development branch revision of FFmpeg on Linux?

So far this is what i did:
cd /usr/local/bin && sudo wget -c https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-$(dpkg --print-architecture)-static.tar.xz && sudo tar -xf ffmpeg-git-* && sudo rm -f ffmpeg-git-*xz && cd ffmpeg-git-*static && ./ffmpeg -version
This one-liner should go to /usr/local/bin, download more or less latest prebuilt ffmpeg version and print version of it.

To run custom ffmpeg command using this new ffmpeg version, just run:
./ffmpeg yourparameters
Once finished, remove the downloaded ffmpeg directory:
cd;find /usr/local/bin/ffmpeg-git-* -delete
