Featuring a description this time (#37)
* Add detail about additional RAM disk slots

Also corrects usernames, some grammar/clarity changes, and adds note about the Windows requirement

* Bullet adjustments and clarify accessing DS Classic Menu on DSi

I changed the PictoChat and flashcard instructions to individual sentences, because in my opinion the single bullet for a step looked bad.

* Add some details to the app installation question

This does technically make it repeat itself a bit, but the invalid title section may only be viewed *after* they've hit the issue.
Also corrects capitalization per CONTRIBUTING.md

* Add details on other ways of connecting

Also removes the Windows hotspot link

* Link to online checksum calculator

* Punctuation and more accurate NWFCUSBC info

Also, the last commit added the AltWFC online player list, but I believe I forgot to mention that

* Add information to top

#### How do I install apps or DSiWare to hiyaCFW's SDNAND?
You will need to use [TMFH](https://github.com/JeffRuLz/TMFH/releases/latest) to install apps to the SDNAND, but older DS homebrew may not be compatible.
- If you would like to install Game Card dumps, you should use a [forwarder](../ds-index/forwarders)
#### Why do I get the #-2435-8325 error code?
If your Nintendo DSi shows an error in this format when booting, with the # being a number, that means that bootstage 2 thinks something is wrong with your SDNAND. This is usually fixed by [reinstalling hiyaCFW](installing).
#### Why do I get "An error has occurred" message when booting hiyaCFW?
When the Nintendo DSi Menu detects a problem it will usually show this generic error message, some of the causes are:
##### The free space bug
The Nintendo DSi Menu has a bug when checking the free space on large storage devices. While this can't occur on the actual NAND (since the chip is only 256 MiB), it can happen when using an SD card.
What works and what doesn't goes by every other range of two gibibytes. For example, having 0-2 GiB of free space works, but 2-4 GiB doesn't. The same goes for 4-6 GiB vs 6-8 GiB, up until you get to the size of your SD card.
The latest hiyaCFW version can create dummy files to work around this, so make sure that you download the latest version of [hiyaCFW](https://github.com/RocketRobz/hiyaCFW/releases/latest/download/hiyaCFW.7z) and copy `hiya.dsi` from "for SDNAND SD card" to the root of your SD card.
##### Over 39 titles
The Nintendo DSi Menu has a limit of 39 titles. If you have more than that, delete some from the folders in `sd:/title` or use [TMFH](https://github.com/JeffRuLz/TMFH/releases/latest) to uninstall them.
##### Too much space used by DSiWare
There is also a limit of 200 blocks (25MB) for DSiWare in the `00030004` folder. This can be worked around by installing as system apps using [TMFH](https://github.com/JeffRuLz/TMFH/releases/latest).
##### Invalid title
There are several things you need to take into account when adding titles to hiyaCFW:
- Game Card dumps cannot be run without being using a [forwarder](../ds-index/forwarders)
- Homebrew need to be built correctly using modern tools to work from the Nintendo DSi Menu
