After finish-up registration, the license key goes to your email. First, extract the datomic itself, then config the dev-transactor-template.properties transactor in ./config/samples/ with your license.

To pull datomic to your Clojure project, make sure you go to https://my.datomic.com/account. After that copy the line:

{#"my\.datomic\.com" {:username "youremail@company.com"
                      :password "xxxxxxx-yyyyyy-xxxx-zzzzz-xxxxxxxxtttt"}}

to ~/.lein/credentials.clj, then encrypt it using gpg, make sure not using passphrase. To encrypt it, run

gpg --default-recipient-self -e ~/.lein/credentials.clj > ~/.lein/credentials.clj.gpg

Now, in your Clojure project project.clj add:

:repositories {"my.datomic.com" {:url "https://my.datomic.com/repo"
                                 :creds :gpg}}
:dependencies [[com.datomic/datomic-pro $VERSION]]
