+## Error: No angular.json file found
+
+Storybook supports Angular multi-project workspace. You can setup Storybook for each project in the workspace. When running npx storybook@latest init you will be asked for which project Storybook should be set up. Essentially, during initialization, the .storybook folder will be created and the angular.json will be edited to add the Storybook configuration for the selected project. Therefore it is important to always run the init command from the root of the workspace, where the angular.json file is located.

 With this, we would like to point out that if you plan on using addons created by our fantastic community, you need to consider that some of those addons might be working with an outdated version of Storybook.
 
 We're actively working to provide a better way to address this situation, but in the meantime, we would ask for a bit of caution on your end so that you don't run into unexpected problems. Let us know by creating an issue in the [Storybook repo](https://github.com/storybookjs/storybook/issues) so that we can gather information and create a curated list with those addons to help not only you but the rest of the community.
