The following steps need to be performed only once for each language that supports stubs:
1. Change the file element type for the language (the element type returned from `ParserDefinition.getFileNodeType()`) to a class that extends [`IStubFileElementType`](%gh-ic%/platform/core-impl/src/com/intellij/psi/tree/IStubFileElementType.java) and override its `getExternalId()` method (see also following item).
-2. In the [plugin.xml](plugin_configuration_file.md), define the `com.intellij.stubElementTypeHolder` extension and specify the interface which contains the `IElementType` constants used by the language's parser.
+2. In the [plugin.xml](plugin_configuration_file.md), define the extension and specify the interface which contains the `IElementType` constants used by the language's parser.
Define the common `externalIdPrefix` to be used for all stub element types (see [](#adding-stub-elements)).
See [`StubElementTypeHolderEP`](%gh-ic%/platform/core-api/src/com/intellij/psi/stubs/StubElementTypeHolderEP.java) docs for important requirements.
