-### Meson
-
-The build process is similar to other Meson builds.
-For a system wide installation requiring root privileges:
-
-```bash
-meson --prefix=/usr build
-ninja -C build install
-```
-
-For a local installation in ~/.local:
-
-```bash
-meson --prefix=~/.local -Dinstall-active-runtime=false build
-ninja -C build install
