+How to use AOTIR in right way ? 
+Hi
+
+I write a simple hello.c to test AOTIR. 
+
+```
+#include <stdio.h>
+#include <stdlib.h>
+
+
+int main()
+{
+    puts("hello, world!");
+    puts("hello, hello, hello  ");
+    return 0;
+}
+```
+
+When I want to use AOTIR feature, 
+
+1. change ~/.fex-emu/Config.json:AOTIRCapture to 1. 
+2. run prog:
+```
+~/source/FEX/build-Release-Thunk/Bin/FEXLoader -- ./hello
+```
+to generate aotir file in ~/.fex-emu/aotir/ directory,  
+3. change AOTIRCatpure back to 0, AOTIRLoad to 1, 
+4. run above command again, now it will use aotir feature 
+
+**First Question:**
+Have a simple way to use this feature ?  I dont want to change config file again and again. 
+
+If i set both AOTIRCapture and AOTIRLoad to 1, then FEX crashed in a null pointer deference.
+
+**Second Question:**
+```
+bogus@bogus:~/source/test/hello$ ~/source/FEX/build-Release-Thunk/Bin/FEXLoader -- ./hello
+try to open file: /home/bogus/.fex-emu/aotir/ld.so.cache-16224829478350186670-sTlP.aotir 
+try to open file: /home/bogus/.fex-emu/aotir/libc.so.6-15624069436683325548-sTlP.aotir 
+hello, world!
+hello, hello, hello  
+```
+I found the FEX not use hello-*.aotir, why ?
+
+**Third Question:**
+what is aotir format? I drag the file into Ghidra , it seems not be recognized.
