{% include toc title="條目內容" %}
### 必讀事項
There have been multiple improvements and advancements to methods for installing CFW over the last short while.
For this reason, it is recommended that you follow [Installing boot9strap (USM)](installing-boot9strap-(usm)) whenever possible.
However, "legacy" or outdated methods are kept here for various purposes. They will require that you have done [Seedminer](seedminer) first.
If you need help, join [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) and ask, in English, for assistance.
