 ## Create a codespace
 1. In your browser, navigate to the [Official Repository of Azure CLI](https://github.com/Azure/azure-cli).
 2. Above the file list, click **Code** > **Codespaces** > **Create codespace on dev**.

 Once codespace is created (takes a while), you will see the following prompt in the integrated terminal:

 ### Prune command-line interface
 Typically, the interface generated directly from the specification isn’t ideal. You can refine it in the [Workspace Editor](https://azure.github.io/aaz-dev-tools/pages/usage/workspace-editor/) to make it meet our requirements. You can open or create a workspace at:

 If everything is selected correctly, you will be redirected to the following UI. You can interactively edit our ideal command line interface based on that:

 When you have completed all the editing in Workspace Editor and clicked EXPORT in its upper right corner. It's ready to switch to [CLI Generator](https://azure.github.io/aaz-dev-tools/pages/usage/cli-generator/) to generate code of Azure CLI:
 1. You need to select the target for generating code. If you don't know where to generate the code, usually Azure CLI Extension is all you need:

 ### Implement custom logic (optional)
 Sometimes, the generated code may not fully meet the requirements. In such cases, you'll need to make some customizations based on it. This process can be relatively complex, so please refer to the [relevant documentation](https://azure.github.io/aaz-dev-tools/pages/usage/customization/).
