 ### Default worker configuration
 Worker should have some default configuration which is applied to worker itself or may be used in given jobs (implicitly if something is missing, or explicitly with special variables). This configuration should be hardcoded and can be rewritten by explicitly declared configuration file. Format of this configuration is yaml like in the job config.
 ```
---- # only one document with all configuration needed
+---  # only one document with all configuration needed
 job-collector:
     hostname: "localhost"
     port: 36587

     file-collector:

+        username: "654321"  # can be ignored in specific modules
+        password: "123456"  # can be ignored in specific modules
+    cache:  # only in case that there is cache module
         cache-dir: "/tmp/cache"

     file: "log.txt"
