+## FAQ
+
+### Where can I find wordlists?
+
+- [SecLists](https://github.com/danielmiessler/SecLists)
+- [DirBuster](https://gitlab.com/kalilinux/packages/dirbuster)
+- [OneListForAll](https://github.com/six2dez/OneListForAll)
+
+### How do I get support? 
+
+Open an issue or ask in the [Discord server](https://cstef.dev/discord).
+
+### Is rwalk stable? 
+
+rwalk is stable but it's still in the early stages of development. It should work for most use cases but there may be bugs.
+
+### Where can I test this tool? 
+
+You can use the [ffuf.me](http://ffuf.me) website to test rwalk.
+I also wrote a [blog post](https://blog.cstef.dev/posts/web-scanning-efficiently) about it with a few cool examples.
