+**systeroid** is implemented using [procfs](https://en.wikipedia.org/wiki/Procfs) which is the virtual file system that is typically mapped to a mount point named `/proc` at boot time. This means checking the value of some kernel parameter requires opening a file in this virtual filesystem, reading its contents, parsing them and, closing the file. In Linux, these dynamically configurable kernel options are available under `/proc/sys` which contains directories representing the sections of the kernel and readable/writable virtual files. For example, to enable/disable IP forwarding, `1` or `0` could be written in `/proc/sys/net/ipv4/ip_forward`.

+### Logo
+
+**systeroid** logo was originally painted by [Ryan Tippery](https://www.ryantippery.com/about) as a part of the [Compositions](https://www.ryantippery.com/compositions/) art collection and it is put together by me using the [Filled Spots](https://www.fontspace.com/filled-spots-font-f30755) font. Shout out to Ryan for letting me use his painting for the logo! <3 Also, check out his [store](https://www.ryantippery.com/store) for a fine piece of similar art. Kudos!
