+## Preview Releases
+
+The preview versions are released 2 weeks before releasing a minor or major version of ABP Framework. They are released for developers to try and provide feedback to us to release more stable versions. 
+
+### Using Preview Versions
+
+#### New Solutions
+
+To create a project for testing the preview version, you can select the "preview" option on the [download page](https://abp.io/get-started) or use the "**--preview**" parameter with the [ABP CLI](CLI.md) new command:
+
+````bash
+abp new Acme.BookStore --preview
+````
+
+This command will create a new project using the latest RC/Preview NuGet packages, NPM packages and solution template. Whenever the stable version is released, you can switch the packages to the stable version for your solution using the `abp switch-to-stable` command in the root folder of your solution.
+
+#### Existing Solutions
+
+If you already have a solution and want to use/test the latest RC/Preview version, use the following [ABP CLI](CLI.md) command in the root folder of your solution.
+
+````bash
+abp switch-to-preview
+````
+
+You can return back to the latest stable using the `abp switch-to-stable ` command later.
+
+````bash
+abp switch-to-stable
+````
+
+### Providing Feedback
+
+You can open an issue on the [GitHub repository](https://github.com/abpframework/abp/issues/new), if you find a bug or want to provide any kind of feedback.
