About GitHub Marketplace
This article applies to installing and purchasing GitHub Apps from GitHub Marketplace. For more information on installing GitHub Apps from a source other than GitHub Marketplace, see "Installing a GitHub App from a third party."
If you install a GitHub App on your personal account and you choose a paid plan, you will pay for your app subscription on your personal account's current billing date using your existing payment method.
如果您选择免费试用付费计划，可在试用期内随时取消，无需付费，但取消后将自动失去对应用程序的访问权限。 您付费的订阅将在 14 天试用结束时开始。 有关详细信息，请参阅“关于 GitHub Marketplace 的计费”。

About installing GitHub Apps
In order to use a GitHub App on your repositories or organization, you must install the app.
When you install an app, you grant the app permission to access the organization and repository resources that it requested. During the installation process, GitHub will tell you which permissions the GitHub App requested. For more information about the REST API requests the GitHub App can make with those permissions, see "GitHub 应用程序所需的权限."
When you install an app, you will also choose which repositories to grant the GitHub App access to.
Before installing a GitHub App, you should ensure you trust the owner of the GitHub App. You should also review the permissions that the GitHub App is requesting and make sure you are comfortable granting those permissions. For more information about the REST API requests the GitHub App can make with those permissions, see "GitHub 应用程序所需的权限."
There is no limit to how many apps you can install.
Difference between installation and authorization
After you install a GitHub App, you may also be asked to authorize the app.
在帐户或组织上安装 GitHub App 时，即表示向应用授予访问其请求的组织和存储库资源的权限。 还需要指定应用可以访问的存储库。
授权 GitHub App 时，即表示根据应用请求的帐户权限授予应用访问 GitHub 帐户的权限。 还需要授予应用代表你执行操作的权限。
无需授权应用即可安装 GitHub App。 同样，无需安装应用即可授权应用。
For more information about authorizing GitHub Apps, see "授权 GitHub Apps."
