# Getting Started

### Setting up the SD-Card
|
|
|
|
The first thing to do is determine if your Switch is vulnerable to fusee-gelee, the exploit we will be using to launch CFW.
|
|
|
|
This vulnerability was independently discovered by several different Switch hacking teams, and multiple variants of it were released to the public in April 2018 after a 90-day disclosure period ended. Nintendo and NVIDIA were made aware of the issue before the public release as a result, and Switch systems that are not vulnerable to the exploit started being spotted in the wild in July 2018. NVIDIA [publicly acknowledged the flaw](https://nvidia.custhelp.com/app/answers/detail/a_id/4660/~/security-notice%3A-nvidia-tegra-rcm-vulnerability) in April as well.
|
|
|
|
Patched units can be identified by their serial number. This number can be found on the bottom of your Switch adjacent to the USB-C port, or in the Settings applet at **System -> Serial Information**.

### Check Vulnerability
|
|
|
|
The homebrew community has crowdsourced a list of known serial numbers which are vulnerable to fusee-gelee.
|
|
|
|
- If your serial number is on this list as "potentially patched", follow the guide and see if your system works.
|
|
- If your serial number is listed as "patched", there is nothing you can do at this time.
|
|
- If your system is patched, it is highly advised to keep it on 4.1.0 or lower, if possible, as there may be a vulnerability for these versions in the far future.

|
?> **Notice**
|
|
If you are unsure if your serial is patched, you can test your console yourself following the instructions [here.](sending_payload.md)

### Console Preparation
|
|
|
|
!> **Important**
|
|
Before setting up the console for homebrew, it is important to have at least one eShop game, application (such as Youtube or Hulu), or a game demo such as [10 Second Run RETURNS](https://www.nintendo.com/games/detail/10-second-run-returns-switch). A game cartridge will also work, but note that the cartridge will have to be inserted in order to run homebrew if you wish to go this route. Once you have a game or application, you are prepared to continue on with the guide.
