 ## Status
 
-**Nothing works yet**. This is very early development code, a long way pre-alpha.
+Very early pre-alpha; user interface mostly works (enough to demonstrate), back end is hardly started.
 
 ## What is it supposed to do?
 
 To understand what I'm aiming for, read [this essay](http://blog.journeyman.cc/2016/10/preparing-for-next-independence.html). Design documentation, such as there is of it yet, is in the *dummy* sub-directory. Also look at [src/clj/youyesyet/db/schema.clj](https://github.com/simon-brooke/youyesyet/blob/master/src/clj/youyesyet/db/schema.clj).

 **NOTE THAT** in the namespace *youyesyet.db.schema*, there are a series of functions *create-xxx-table!*. These are a snare and a delusion; they are how I originally bootstrapped the database, but are no longer used (and should probably be deleted). The database is now constructed using [migratus](https://github.com/yogthos/migratus).
