:exclamation: | If you are having trouble installing NOJ or requires additional help setting up, you can contact us via [email protected] or start an issue. :-----------: | :----------------------------------------------------------------------------------------------------------------------------

CentOS 8 will be recommended for hosting NOJ, but all major operating systems are theoretically supported.

We recommend running NOJ on the following platforms:

  • Ubuntu 20.04 and above
  • CentOS Linux release 8.0 and above
  • Windows 10 Professional (requires additional setup)

Your web browser should be one of the following:

| ChromeChrome | FirefoxFirefox | IE Internet Explorer | Edge Edge | OperaOpera | SafariSafari | |:---------:|:-----------:|:-------------:|:-----------------:|:----------------:|:----------------:| |69 and above|62 and above|Not supported|69 and above|Not Supported|13.1 and above|

  • Chrome 69 and above
  • Edge 69 and above
  • Firefox 62 and above
  • Safari 13.1 and above

We do not provide any support for Opera, which doesn't mean Opera cannot access NOJ without error, it just means issues about compatibilities of Opera will not be fixed.

For installation options and troubleshooting tips, see NOJ Documentation.
