Notes from setting dato up from scratch

Hi @sgrove,

I'm excited about playing around with dato — seems like the future. I've got it running, but had a few problems along the way. After I cloned, I tried to run figwheel and got:

dato/ on master 
› lein figwheel
Possibly confusing dependencies found:
[lein-cljsbuild "1.0.6" :exclusions [org.clojure/clojurescript]] -> [lein-cljsbuild/cljs-compat "1.0.0-SNAPSHOT"] -> [org.clojure/clojure "1.5.1"]
 overrides
[lein-ancient "0.6.7"] -> [version-clj "0.1.2"] -> [org.clojure/clojure "1.6.0"]
 and
[lein-ancient "0.6.7"] -> [ancient-clj "0.3.9" :exclusions [com.amazonaws/aws-java-sdk-s3]] -> [org.clojure/clojure "1.6.0" :exclusions [joda-time org.clojure/clojure]]
 and
[lein-ancient "0.6.7"] -> [rewrite-clj "0.4.12"] -> [org.clojure/clojure "1.6.0" :exclusions [org.clojure/clojure]]

Consider using these exclusions:
[lein-ancient "0.6.7" :exclusions [org.clojure/clojure]]
[lein-ancient "0.6.7" :exclusions [org.clojure/clojure]]
[lein-ancient "0.6.7" :exclusions [org.clojure/clojure]]

Aborting due to :pedantic? :abort

I made the suggested changes, and the dependencies resolve fine. But now:

Subprocess failed

Running git submodule init && git submodule update solved this.

Also, I only needed the following env vars in my profiles.clj to get lein run working:

           :env          {:is-dev true
                          :datomic-local-uri "datomic:dev://localhost:4334/dato"}

Found out through experimentation that the database name doesn't matter, and doesn't need to exist before you do lein run. And that PORT is the web server port, not DATO_PORT =)

I'm still having a bit of trouble with the nrepl server, but I'll mess around with that when I actually need it.

Might be worth adding a few notes to the README for the next guy who comes along?

Cheers.
