# Contributing to ABP Angular UI We would love for you to contribute to ABP Angular UI and help make it even better than it is today. # Development Run `yarn` to install all dependencies, then run `yarn prepare:workspace` to prepare the ABP packages (might take 2 minutes). Run `yarn start` to start the `dev-app`. Navigate to http://localhost:4200/. ## Package [Symlink Manager](https://github.com/mehmet-erim/symlink-manager) is used to manage symbolic link processes. Run `yarn symlink copy` to select the packages to develop. ## Application The `dev-app` project is the same as the Angular UI template project. `dev-app` is used to see changes instantly. If you will only develop the `dev-app`, you don't need to run `symlink-manager`. > Reminder! If you have developed the `dev-app` template, you should do the same for the application and module templates. For more information, see the [docs.abp.io](https://docs.abp.io) # Committing changes Before you commit, please ensure that your code passes the existing unit tests.
