+# Project Wizards
+
+Creating a project in IntelliJ-based IDEs is achieved with [project wizards](https://www.jetbrains.com/help/idea/new-project-wizard.html) gathering information about the created project and generating it.
+
+IntelliJ Platform provides APIs to implement wizards:
+- [](new_project_wizard.md) — available since 2024.2
+- [](legacy_project_wizard.md) — an old API, not recommended to implement in plugins targeting versions 2024.2 and newer
