 The following will create and sign a token, then verify it and output the original claims:
 
-     echo {\"foo\":\"bar\"} | bin/jwt -key test/sample_key -alg RS256 -sign - | bin/jwt -key test/sample_key.pub -verify -
+     echo {\"foo\":\"bar\"} | ./jwt -key ../../test/sample_key -alg RS256 -sign - | ./jwt -key ../../test/sample_key.pub -alg RS256 -verify -
 
 To simply display a token, use:
 
-    echo $JWT | jwt -show -
+    echo $JWT | ./jwt -show -
