 We can start the TCP server as follows:
 
 ````shell
-java -jar target/ixa-pipe-nerc-1.5.3.jar server -l en --port 2060 -m en-91-18-conll03.bin
+java -jar target/ixa-pipe-nerc-$version.jar server -l en --port 2060 -m en-91-18-conll03.bin
 ````
 Once the server is running we can send NAF documents containing (at least) the term layer like this:
 
 ````shell
- cat file.pos.naf | java -jar ../ixa-pipe-nerc/target/ixa-pipe-nerc-1.5.3.jar client -p 2060
