+**XFunctions** is meant to be a completely compatible implementation that covers the full functionality of XLOOKUP and XMATCH.
 
 The add-in should work in all Windows versions of Excel, with separate 32-bit and 64-bit add-ins.
+If the add-in is loaded into a version of Excel that already supports the XLOOKUP and XMATCH functions, the add-in will register the add-in functions under the names XLOOKUP.FROM.ADDIN and XMATCH.FROM.ADDIN respectively.

 TODO
 ----
-* Decide whether to use the same names or different ones (e.g. "XLookup_" to make clear it's not the built-in "XLOOKUP" function)
 * Understand compatibility for sheets between real functions and the XFunctions version - internally the workbook knows whether a function in a formula is a built-in function or an xll function . . . how does it behave when loaded backwards or forwards?
-* Decide what to do when loading in an instance where the real functions are present
 * Clean up, add tests etc.
+* Fix up example books again, in a version where XLOOKPU is not yet supported.
