📝 added some commands for assembling / disassembling (for aarch64 specifically)

 ## Programming languages
 * **C** - `gcc -std=gnu99 -Werror -Wfatal-errors -Wall -Wpedantic blub.c -o blub`
     * if necessary, remove `-Wpedantic`, since it warns for features definitely included by using `gnu99` as compiler
-* **C++** - `g++ -Wall -c blob.cpp blub.cpp` -> `g++ -Wall -o blub blob.o blub.o`
+    * `gcc -c -std=gnu99 -Werror -Wfatal-errors -Wall -Wpedantic blub.c -o blub` the `-c` to get object file only instead of binary
+* **C++** - 
+    * `g++ -pedantic -Wall -Wextra -Werror -c blob.cpp blub.cpp` -> object files
+    * `g++ -Wall -o blub blob.o blub.o` -> binaries
     * `blob.cpp` gets linked (blub.cpp would likely start with something like `#include "blob.h"`)
+* **Assembly** - (this is called *assembling* instead of *compiling*) `gcc -c blub.s`
+    * on systems that aren't ARM:
+        1. `aarch64-linux-gnu-gcc -c blub_asm.s`
+        2. `aarch64-linux-gnu-gcc -c blub_c.c`
+        3. `aarch64-linux-gnu-g++-10 -c blub.cpp`
+        4. linking: `aarch64-linux-gnu-g++-10 -o blub blob.o blub_asm.o blub_c.o`
+        5. running: `qemu-aarch64 ./blub`
+    * assembling and disassembling single commands:
+        - `echo "adds x0, x0, #5" | llvm-mc -triple=aarch64 --show-encoding`
+        - `echo "0x00 0x14 0x00 0xb1" | llvm-mc -triple=aarch64 -disassemble --show-encoding`
 * **System Verilog** - `iverilog -Wall -g2012 1.sv 2.sv 3_tb.sv 3.sv -o 3_tb` <- tb for testbench simulation
