+- Assemble assembly code file into object file with machine code:
+
+`llvm-mc --filetype=obj -o {{path/to/output.o}} {{path/to/input.s}}`
+
+- Disassemble object file with machine code into assembly code file:
+
+`llvm-mc --disassemble -o {{path/to/output.s}} {{path/to/input.o}}`
+
+- Compile LLVM bit code file into assembly code:
+
+`llvm-mc -o {{path/to/output.s}} {{path/to/input.bc}}`
+
+- Assemble assembly code from standard input stream and show encoding to standard output stream:
+
+`echo "{{addl %eax, %ebx}}" | llvm-mc -show-encoding -show-inst`
+
+- Disassemble machine code from standard input stream for specified triple:
+
+`echo "{{0xCD 0x21}}" | llvm-mc --disassemble -triple={{target_name}}`
