 # Creating a Project and Obtaining Source Code
 
 
-When creating an OpenHarmony project, DevEco Device Tool automatically downloads the source code in one of the following types, depending on the use case: **OpenHarmony Stable Version**, **OpenHarmony Sample**, and **HarmonyOS Connect Solution**.
-
-
-**OpenHarmony Stable Version** provides source code of an OpenHarmony stable version, which is acquired from a mirror site. The OpenHarmony-v1.1.4-LTS, OpenHarmony-v3.0.3-LTS, and OpenHarmony-v3.1-Release versions are supported.
+When creating an OpenHarmony project, DevEco Device Tool automatically downloads the source code in one of the supported types.
 
+Source code of an OpenHarmony stable version is downloaded from a mirror site. The following versions are available: OpenHarmony-v3.0.3-LTS, OpenHarmony-v3.1-Release, OpenHarmony-v3.2-Beta3, OpenHarmony-v3.2-Beta4, OpenHarmony-v3.2-Beta5, and OpenHarmony-v3.2-Release.
 
 The source code from a mirror site is generally what's available when the stable version is released. Therefore, it may be out of date. To acquire the latest source code of a version, follow the instructions in [Acquiring Source Code from the Gitee Code Repository](../get-code/sourcecode-acquire.md). After acquiring the source code, import it to DevEco Device Tool by following the instructions in [Importing OpenHarmony Source Code](https://device.harmonyos.com/en/docs/documentation/guide/open_project-0000001071680043).
