 SLS is a statically-typed, stack-based language with pure postfix notation
 combining the execution model of HP's RPL, the type system of C and Rust, and
 modern array operations from Uiua.

+
+**MacOS**
+
+Reference Linux build instructions.
+
+For C there is the `python3 build.py macos` command, but it is untested as I
+didn't test it on a Mac. I also don't know if `python3 build.py build` would also
+work on a Mac.
+
+Python and Rust should just be the same or similar to Linux.
+
+**RP2040**
+
+Only tested on Linux. Only SLS_C supports RP2040.
+
+Install Pico SDK to `~/pico/pico-sdk`, or set environment variable
+`PICO_SDK_PATH` to your installation path. You will also need to install the
+appropriate compiler.
+
+Debian GNU/Linux
+```bash
+sudo apt install gcc-arm-none-eabi

 **C** was my selected language. It was an excellent choice for my project as it
 is well suited for systems programming. It is a low level, yet powerful
 language. While string utilities are not as robust as most modern languages, I
 still feel like it was an excellent choice. Other major interpreted languages
 also use C to implement their interpreters, such as Lua and Python.
 
+Manual memory management was a slight difficulty for me. The only way I could
+find what was causing a segmentation fault was to run the binary with `gdb`.
+Still my experience programming C in a Linux environment was fun and rewarding.
+I became accustomed to utilizing the man pages (or manual pages) for
+documentation on the C standard library.
+
+I did use structs and unions heavily which we learned about when we looked at C.
+With them I was able to use polymorphism in defining tokens and data types.
+
+I am able to successfully compile and run this implementation on a Raspberry Pi
+Pico with a RP2040 microcontroller. You can interact with the REPL over a serial
+connection.

 **Rust** was the first language I tackled porting my project to. I am not as
 familiar with Rust as I am Python, so thats why I wanted to get going on this
 port first. I avoided using external libraries with C as they can be famously
