### Required Reading
请在下表中按照你的系统版本选择对应的页面。 Note that the "from" and "to" fields are inclusive. 也就是说，举个例子“从9.0.0到9.2.0”这一行表示9.0.0，9.1.0，和9.2.0。
Additionally, note that the last two columns of the chart refer to the last number of your version (which corresponds to the browser version installed to the system). 如果版本号以0结尾，则说明没有浏览器，如果大于0则表示浏览器已经安装。
例如，如果系统版本为“5.0.0-0U”，你需要定位到“无浏览器”这一列和“从5.0.0到5.1.0”这一行，因为系统版本在那个范围内并且无浏览器 。
Your device version can be found at the bottom right of the top screen of the System Settings.

**If you are unable to follow the instructions corresponding to your specific version due to missing prerequisites, then you should either update to the latest version or use the "All Versions" row for methods that work regardless of system version.**
For all versions you can also [Cartridge Update](cart-update) (or use a standard system update) to get to a higher version in the same column to follow its instructions.
如果你已经破解过你的3DS，并安装了基于EmuNAND的自制系统，请在SysNAND上进行本教程的所有操作。 Replace any files that already exist. Your data will be transferred from EmuNAND to your new B9S install at the end. If you use menuhax, you should [clear Home Menu's extdata](troubleshooting#clear-home-menu-extdata) to remove it before beginning.
This page is for instructions on how to install boot9strap to a *stock* 3DS or 2DS. If you already have arm9loaderhax installed and are looking to update to boot9strap, follow [A9LH to B9S](a9lh-to-b9s).
