+# Gene Info Service for the iBeetleBase project
 
-This project uses Quarkus, the Supersonic Subatomic Java Framework.
 
-If you want to learn more about Quarkus, please visit its website: https://quarkus.io/ .
+This microservice is based on Quarkus (version 1.4.2).
+It can be used for querying gene information in JSON format.
+Currently, it holds gene information for Tribolium castaneum and Drosophila melanogaster.
 
 ## Running the application in dev mode
 
@@ -10,6 +11,20 @@ You can run your application in dev mode that enables live coding using:
 ```
 ./mvnw quarkus:dev
 ```
+## Querying the Service
+
+Once the service is running, gene information can be queried using cURL like this:
+```
+curl -X GET "http://localhost:8080/geneinfo/current/v1/DATABASE/ID"
+```
+where DATABASE is either `tribolium` or `flybase` and ID is the gene identifier.
+Gene identifiers can be in TC format (e.g. `TC016101`) or in FBgn format (e.g. `FBgn0010400`).
+Replacing ID with `identifiers` returns a list of all gene IDs for the specific database.
+
+Multiple genes can be queried with comma-separated requests:
+```
+curl -X GET "http://localhost:8080/geneinfo/current/v1/id?=TC016101,TC016102,FBgn10400"
+```
