 ## Functionality missing from the original
 
 * Multithreading
 * Networking
+* FFI and dynamic module loading
 * Some mathematical functions (`math/erf`, `math/erfc`, `math/gamma`, `math/log-gamma`, `math/nextafter`)
 * Secure RNG source (`os/cryptorand`)
-* Full terminal editing features (you can compile with them, but the REPL will crash often)

 3. Run `make`.
 4. Copy the contents of `bin` directory (`janet.exe` and `CWSDPMI.EXE`) to your DOS system.
 
+## FAQ
+
+### Why?
+
+Janet already is an extremely portable language that can run "as is" on a lot of systems and architectures, but DOS still was on the list of missing targets. Meanwhile, retro x86 hardware could benefit from running a modern, practical Lisp system, even if it would be fully offline and single-threaded.
+
+### Why amalgamated source code?
+
+Because it was easier to write my own Makefile for.
+
+### Can the same source code be used for building Janet for other platforms?
+
+Yes, but you will have to re-enable "standard" features in `janet.h` by commenting out corresponding `#define` directives, and also update the Makefile accordingly.
+
+### Was genAI used for porting?
+
+As the codebase is quite long, genAI was used for identifying some problematic bits within it and some intermediate experimentation, but all final patches were fully hand-written.
+
+### Will you submit your patches as a PR to the upstream Janet repo?
+
+Maybe.
