 Qiling has supported **Gdb remote debugging** now (x86, x86-64 for now).
 
-Currently supported features include `si`, `ni`, `c`, read register, read memory, add/remove breakpoint.

 # Qiling Gdbserver
 
-Qiling supports **Gdb remote debugging**, which listens at default port **9999** if enable.
+Qiling supports **Gdb remote debugging** with an embedded gdbserer.

-Run gdb and `set architecture i386:intel` for x86 or `set architecture i386:x86-64` for x86-64
+By default, gdbserver listens at **localhost**, port **9999**.
 
-Then `target remote ip:port` and run the python script.
-
-Currently supported commands include `si`, `ni`, `c`, `k`, read register, read memory, add/remove breakpoints.
+The emulated code will break at entrypoint, waiting for connection & control from gdb client.

 ### Debug with IDA
 
-The script is the same as above.
+Firstly, run Qiling code, with gdbserver enable, like in the sample script above.
 
-Run IDA and set options like this:
+Then run IDA and set options like in the below screenshot:
 
 ![GDB-IDA](./GDBSERVER-IDA.png)
 
-Note: Make sure you have selected the arch of target file.
-
-Then run the script and you can Debug wth IDA now.

-## Example
+Note: Make sure you select the architecture of target code.
 
 Below is an example on how we use gdb to debug an x86-64 binary in Qiling.
