+# CTF tools & some other stuff  
+
+**2023/01/21 Update:** I rarely play CTF now, so some of the tools might be outdated.
+
+## [ctf-tool](https://github.com/bruce30262/CTF/tree/master/ctf-tool)  
+Some installation scripts and test files for testing tools.
+
+## [Script](https://github.com/bruce30262/CTF/tree/master/script)
+Some useful scripts for CTF pwn challenges.
+
 [exp_template.py](https://github.com/bruce30262/CTF/blob/master/script/exp_template.py)  
 python script template for CTF pwnable challenges, using [pwntools](https://github.com/Gallopsled/pwntools).  
 
 [armtool.alias](https://github.com/bruce30262/CTF/blob/master/script/armtool.alias)  
-alias setting for qemu & ARM toolchain.
+alias setting for qemu & ARM toolchain. See also: [set_arm_env.sh](https://github.com/bruce30262/CTF/blob/master/script/set_arm_env.sh).
 
 [bruceutils.py](https://github.com/bruce30262/CTF/blob/master/script/bruceutils.py)  
 Some utilities (ex. pack & unpacking data, socket connection ...) written by me, in case of there is no pwntools to use.  
 
 [brucepwn](https://github.com/bruce30262/CTF/blob/master/script/brucepwn/brucepwn/brucepwn.py)  
-Self made utilities for CTF pwn challenges.  
+Self made utilities for CTF pwn challenges. ( **Written in python2**. Will update when I feel like it :P )  
 
 [change_ld.py](https://github.com/bruce30262/CTF/blob/master/script/change_ld.py)  
 Simple utility to assign new ld.so of the given binary.
 
-## Debugger
-Some config files & tools for the debugger  
-  
-[gdb](https://github.com/bruce30262/CTF/blob/master/debugger/gdb)  
-* Using [pwndbg](https://github.com/pwndbg/pwndbg) as the default GNU debugger.  
-* Will detect if gdb-multiarch is needed.
-
-[gef](https://github.com/bruce30262/CTF/blob/master/debugger/gef)  
-* [GEF](https://github.com/hugsy/gef) is also a great debugger.  
-* Will detect if gdb-multiarch is needed. 
-
-[gdbp](https://github.com/bruce30262/CTF/blob/master/debugger/gdbp)  
-* [My own peda](https://github.com/bruce30262/peda).  
-* Had used this for pretty long time, however I think it's time to move to a more updated gdb plugin.
-
-### Setting:  
-* Put `gdb`, `gef`, `gdbp` in the home directory, all of them must be executable.  
-* Add the alias setting in `dbg.alias`.

-## Shellcode
- shellcode for `execve("/bin/sh", 0, 0)`.  
- Currently support `x86`, `x64`, `ARM` & `AArch64`.  
- Also [scutils](https://github.com/bruce30262/CTF/tree/master/shellcode/utils) helps me generate shellcode more conveniently.
+## [Shellcode](https://github.com/bruce30262/CTF/tree/master/shellcode)
+Basic shellcode for `execve("/bin/sh", 0, 0)`. Currently support `x86`, `x64`, `ARM` & `AArch64`.  
+Nowadays you might just want to use [pwntools shellcraft](https://docs.pwntools.com/en/stable/shellcraft.html) instead, it's way more convenient.
