EOS

cat << 'EOS'
You should make the following settings:
    export VAR_HOME=$HOME/.variant
    export VAR_VERSION=0f2c812942c99ec3f32e44848d8bd3f91e8300ed
    export PATH=$HOME/.variant/bin:$PATH

If you want to change the version to be executed, change `VAR_VERSION`:
    export VAR_VERSION=0.10.0
    export VAR_VERSION=master
