# Station checker > Read a station document before installing it: what Quasar would refuse, and what you would be accepting. Source: https://quasar.achaverot.fr/docs/tools/station-checker/ Paste a station document. This runs the checks Quasar runs before storing one, and shows the permissions in the same plain words the install screen uses — which is the part worth reading when somebody sends you a station. Nothing is installed and nothing leaves this page. Writing one instead? Use the [station builder](/tools/station-builder/).
