 # Integration:
 ruri is ready to integrate into other projects, with the MIT License, it is compatiblte to be redistribute with almost all license, or commercial/closed source.      
 An example is ruri's own build action [build-all.sh](build/build-all.sh), it runs containers for 9 different architectures to build itself, that shows its broad application prospects.      
+Another example is [rurima](https://github.com/Moe-hacker/rurima), I made ruri built-in into it, so it can be run as a subcommand.      
 See [Integration](doc/Integration.md) for a guide to integrate ruri into your projects.    
 # Usage:

 You can also add other options like `ruri -D -o test.conf -d cap_chmod -k cap_sys_admin -w -u /test /bin/sh`      
 So next time, just use `ruri -c /path/to/test.conf` to run the container.      
 ## integrate with source:
-If your project supports, you can also edit the main.c, remove `main()` function and use ruri as a lib. But make sure that you know how main.c works, especially how CONTAINER struct works.

+main() has been replaced to ruri, and every funcion in ruri have ruri_ or nekofeng_ prefix now, so you need not worry about conflicts of symbols now.
