It currently works with Maven only, and not with Docker. A working Dockerfile will be added later.

+# Twitter Service
+
+
+## API
+
+You can use the search under: [http://localhost:8084/search/tweets.json?q=Google](http://localhost:8080/search/tweets.json?q=Google)
+where `q` is your search string.
+
+It mainly mirrors the search API from Twitter. My implementation contains some basic fields with the same names as in
+the official API. If you need more, please let me know.
+
+
+## API Keys
+
+Unfortunately you have to provide your own API Keys, as sharing them is forbidden. In the worst case there would be five
+people using the same keys at the same time. This probably asks for a ban.
+
+I really don't want to risk it, as my application for a [Twitter Developer Platform](https://developer.twitter.com/)
+account was ridiculously complicated. You have to answer four questions, with at least 400 (?) words, and as detailed as
+possible. My application apparently wasn't detailed enough, so they asked me follow up questions. After two emails, one
+with ~1.200 words, they were finally satisfied.
+
+Furthermore people with an existing account, like I had, can't create new apps anymore, unless they apply again.
+
+So I would advise you to [apply for an account](https://developer.twitter.com/en/apply-for-access) yourself, or maybe
+ask someone else from the group if they have a spare key.
+
+The keys then go into `application.yml` below `oauth:`, i.e. `consumer-key`, `consumer-secret`, `access-token`,
+`access-token-secret`.
+
+
+## Docker
+
+The `Dockerfile` doesn't work yet, it's WIP.
