However, Cmder can in fact run in a variety of other terminal emulators, and even integrated IDEs. Assuming you have the latest version of Cmder, follow the following instructions to get Cmder working with your own terminal emulator.

For instructions on how to integrate Cmder with your IDE, please read our [Wiki section](https://github.com/cmderdev/cmder/wiki#cmder-integration).
