+# Eclipse StatET - R Help Server
+
+## Requirements
+
+  * Java
+  * RJSrv
+
+## Configuration
+
+Edit the configuration(s) for the R environments in the folder `renvs`:
+  - One configuration file per R environment
+  - The name of the file is the id of the R environment
+
+The server is based on Spring Boot; see documentation of Spring Boot e.g. how
+to configure the webserver.
+
+## Run the Server
+
+To run the server just start the jar:
+
+    java -jar org.eclipse.statet.rhelp.server.jar &
+
+### Special modes
+  * `-index-and-exit` - creates or updates the help index only
+
+## Access the Server
+
+### URI for API
+The URI to access the help of an R environment via IDE is specified as follows:
+
+    http://<name or ip>:<port>/<env id>
+
+For example: `http://serverwithhelp:8080/r35`
+
+The following defaults can be optionally omitted:
+  - `<port>` = 80
+  - `<env id>` = default
+
+So `http://serverwithhelp/` is equal to `http://serverwithhelp:80/default`.
+
+### Web
+The URL to access the help using a webbrowser is:
+
+    http://<name or ip>:<port>/rhelp/browse/<env id>
+
