	== Synopsis ==		== Synopsis ==
	NextPi was a customised DietPi version distributed with the original "KS1" nexts, it has been superseeded by NextPi2 - which ~~will work~~ on both KS1 and KS2 nexts (and other compatible clones) as long as the SD card is large enough (>=16GB).		NextPi was a customised DietPi version distributed with the original "KS1" nexts, it has been superseeded by NextPi2, an even more customised distro - which works on both KS1 and KS2 nexts (and all other compatible clones) as long as the SD card is large enough (>=16GB).

	NextPi ~~(and NextPi2) is~~ optimised for Read Only filesystems (making them safe to turn off without a clean shutdown) and are ~~designed~~ with the specific use of embedded in an 8-bit computer in mind.		All NextPi versions are optimised for Read Only filesystems (making them safe to turn off without a clean shutdown) and are intended with the specific use of embedded in an 8-bit computer in mind, especially the ability to power the computer off without issuing a shutdown command.

	The term Accelerator is somewhat of a misnomer, technologically. It's not an accelerator in the terms that it accelerates the next itself, but it permits the execution of code on a much faster processor - that of the Pi Zero. Think of it as a co-processor, or "companion computer".		The term Accelerator is somewhat of a misnomer, technologically.

Think of it as a co-processor, or "companion computer".

	The Linux install that makes up NextPi is not usable as a "General Purpose" operating system due to the read only nature of the main filesystem. The read only nature ~~also~~ helps minimise any breaking changes to the operating system that could prevent future patches installing correctly.		The Linux install that makes up NextPi is not usable as a "General Purpose" operating system due to the read only nature of the main filesystem and lack of network connection support as standard. The read only nature helps minimise any breaking changes to the operating system that could prevent future patches installing correctly as well as the aforementioned "easy power-off".

	NextPi does have writable FAT16 user partitions which can be used for user software development ~~and misc~~. ~~purposes although, for~~ developed games using the Pi for media playback, and executing assistant code /ram is more suited (see the documentation included with NextPi about filesystems for more details) ~~and NextPi 2 also has a~~ Persistent Cache system, managed by the nextpi-cache CLI API.		NextPi does have writable FAT16 user partitions which can be used for user software development, etc. For developed games using the Pi for media playback, and executing assistant code `/ram` is more suited (see the documentation included with NextPi about filesystems for more details) or leveraging the NextPi2 Persistent Cache system, managed by the nextpi-cache CLI API, to allow games to upload new functions one, and use them repeatedly after power-cycle.
