+# Is Hilbish POSIX compliant?
+No, it is not. POSIX compliance is a non-goal. Perhaps in the future,
+someone would be able to write a native plugin to support shell scripting
+(which would be against it's main goal, but ....)
+
+# Windows Support?
+It compiles for Windows (CI ensures it does), but otherwise it is not
+directly supported. If you'd like to improve this situation,
+checkout [the discussion](https://github.com/Rosettea/Hilbish/discussions/165).
+
+# Where is the API documentation?
+The builtin `doc` command supplies all documentation of Hilbish provided
+APIs. This will be on the website in the near future.
+
+# Why?
+Hilbish emerged from the desire of a Lua configured shell.
+It was the initial reason that it was created, but now it's more:
+to be hyper extensible, simpler and more user friendly.
