Frequently Asked Questions

  • Where do the definitions come from?

    Definitions come from our database and are sourced from official documentation and manual pages so that you don't have to read them. We have technical writers constantly improving definitions to make sure they're consistent, concise and can stand alone. We are also constantly adding programs to our database. 
  • What's the difference between the kmdr-cli and the browser extension?

    By nature of already using their browser, the learner experience is more streamlined with the browser extension when taking advantage of the command details and features in app.kmdr.sh. The extension also supports more advanced features than kmdr-cli such as multi-line commands. The definitions returned in kmdr-cli and the browser extension are the same.
  • How can I receive software updates?

    Chrome and Firefox users will receive updates as soon as we release the new version.
  • What browsers are supported?

    Chrome and Firefox
  • What CLI programs/tools does kmdr understand?

    There are hundreds! You can visit the detailed list at app.kmdr.sh/coverage
  • Does the extension work on any website?

    So long you are able to select text on the website, then yes! It does not render definitions for commands in images or PDFs.
  • What payment methods do you accept?

    Google Pay or any other credit card like Visa, MasterCard and American Express. We use Stripe as our payment platform.
  • Does kmdr work with scripts?

    The ability to select multiple lines of code using the extension means you can get explanations for full files, or parts of a script that you want to understand. The program, subcommand or option that you want to learn may very well be a part of a complex structure that's multiple lines and when that's the case you'll want to use the kmdr extension. We use syntax highlighting to help you differentiate the parts of the code you are looking at and explain the attributes of the commands within it.
  • Which shells can be parsed by kmdr?

    Bash
  • Does it work offline?

    No. As of now, you can only use kmdr-cli and the browser extension as long as those clients can reach out to our API backend servers.
