[Help needed] Conditional build with"sender" tag

Hello

I’ve read the Conditional Builds but I don’t understand where should I declare the condition.

I want to trigger a build ONLY if the sender is not Travis bot.

Where should I declare my condition?

PS: right now I’m using sender condition as declared in travis-conditions

if: sender != traviscibot OR sender != Travis # Don't build if build request was triggered by Travis

    - npm run build # Build new Readme
    - awesome_bot README.md --allow-redirect --allow-ssl --skip-save-results --allow-dupe # Check the links
