+## 'function' keyword is non-standard. Delete it.
+
+### Problematic code:
+
+```sh
+#!/bin/sh
+function hello() {
+  echo "Hello World"
+}
+```
+
+### Correct code:
+
+```sh
+#!/bin/sh
+hello() {
+  echo "Hello World"
+}
+```
+
+### Rationale:
+
+`function` is a non-standard keyword that can be used to declare functions in Bash and Ksh.
+
+In POSIX `sh` and `dash`, a function is instead declared without the `function` keyword as in the correct example. 
+
+### Exceptions:
+
+None.
+
+### Related resources:
+
+* Help by adding links to BashFAQ, StackOverflow, man pages, POSIX, etc!
