## Working with your own SDK
To create your own SDK, You need to create a class extends [SdkType](https://upsource.jetbrains.com/idea-ce/file/idea-ce-974a6ed084613aa5b0e345fbeb50de59720ab283/platform/lang-api/src/com/intellij/openapi/projectRoots/SdkType.java), leave `saveAdditionalData` blank, and register it in the `com.intellij.sdkType` extension point.

To let user select an SDK, see [ProjectJdksEditor](https://upsource.jetbrains.com/idea-ce/file/idea-ce-8c9022ae739b82b2ee8f3355da98b9bbce2cb915/java/idea-ui/src/com/intellij/openapi/projectRoots/ui/ProjectJdksEditor.java).
However, it is not recommended to use "SDK" in non-IDEA IDEs. "SDK" is IntelliJ-specific and doesn't work in PyCharm, RubyMine, etc.
The most recommended way of managing your "SDK" settings is to create a [`CustomStepProjectGenerator`](https://upsource.jetbrains.com/idea-ce/file/idea-ce-8c9022ae739b82b2ee8f3355da98b9bbce2cb915/platform/lang-impl/src/com/intellij/ide/util/projectWizard/CustomStepProjectGenerator.java)
implementation and save settings in a [`PersistentStateComponent`](http://www.jetbrains.org/intellij/sdk/docs/basics/persisting_state_of_components.html).
