+# Operating systems
+
+This project has views that promote a relatively minimal use of computers. These views align more with certain operating systems than others.
+
+## Advisable
+
+- **DOS**
+  - *[FreeDOS](https://freedos.org/)*  
+  (~ 15 MB, 'LiteUSB' edition)
+- **POSIX**
+  - *[Minix](https://minix3.org/)*  
+  (~ 288 MB, 'x86 CD' edition)
+  - **BSD**
+    - *[NetBSD](https://netbsd.org/)*  
+    (~ 622 MB, 'amd64 CD' edition)
+  - **Minimal Linux kernel**
+    - *[Tiny Core Linux](http://tinycorelinux.net/)*  
+    (~ 17 MB, 'Core' edition)
+
+
+
+## Inadvisable
+
+### Proprietary operating systems
+
+If the user is not entirely in control of the software, what's the point?
+
+### Operating systems using the generic Linux kernel
+
+The generic version of the Linux kernel is enormous as compatibility is a key feature of the Linux kernel.
+
+This extreme level of compatibility is futile in our case. A project that is relatively comparable in terms of compatibility is NetBSD, which provides separate releases per platform.
+
+Compiling the Linux kernel in order to reduce its size is a solution to this problem: an extreme example of this practice is the Tiny Core Linux project, which offers a functional operating system using BusyBox and the Linux kernel starting from only 17 MB.
