Note that if you know enough about CouchDB you can install the application without CouchApp. However, this is so inconvenient that I recommend you just install CouchApp.
Create a database called surveycouch and then set up
point to it. For example, copy
and change the database URL to something appropriate.
Next, push the application into CouchDB by running
couchapp push local (if you changed the name of the database location, you'll need
to use the same thing here).
Finally, visit http://localhost:5984/surveycouch/_design/surveycouch/index.html to see your application. Note that if you're CouchDB is running on another domain or port you will have to edit the URL accordingly.
