+Custom
+======
+
+Add any custom aliases/settings to the `init.zsh` file.
+
+Any functions should go in the `functions` folder, where the name of the file is the name of the function.
+
+For example, this function from your .zshrc:
+```
+foo() {
+  print 'bar'
+}
+```
+
+becomes a file named 'foo' in the functions folder containing:
+```
+print 'bar'
+```
