--   The module itself, following proper naming conventions: `python.d/<module_dir>/<module_name>.chart.py`
--   A README.md file for the plugin under `python.d/<module_dir>`. 
--   The configuration file for the module: `conf.d/python.d/<module_name>.conf`. Python config files are in YAML format, and should include comments describing what options are present. The instructions are also needed in the configuration section of the README.md 
--   A basic configuration for the plugin in the appropriate global config file: `conf.d/python.d.conf`, which is also in YAML format.  Either add a line that reads `# <module_name>: yes` if the module is to be enabled by default, or one that reads `<module_name>: no` if it is to be disabled by default.

+# Gearman
+
+Module monitors Gearman worker statistics. A chart
+is shown for each job as well as one showing a summary
+of all workers.
+
+Note: Charts may show as a line graph rather than an area 
+graph if you load Netdata with no jobs running. To change 
+this go to "Settings" > "Which dimensions to show?" and 
+select "All".
+
+Plugin can obtain data from tcp socket **OR** unix socket.
+
+**Requirement:**
+Socket MUST be readable by netdata user.
+
+It produces:
+
+ * Workers queued
+ * Workers idle
+ * Workers running
+
+### configuration
+
+```yaml
+localhost:
+  name     : 'local'
+  host     : 'localhost'
+  port     : 4730
+  
+  # TLS information can be provided as well
+  tls      : no
+  cert     : /path/to/cert
+  key      : /path/to/key
+```
+
+When no configuration file is found, module tries to connect to TCP/IP socket: `localhost:4730`.

+# There are 2 sections:
+#  - global variables
+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# penalty indicates whether to apply penalty to update_every in case of failures.
+# Penalty will increase every 5 failed updates in a row. Maximum penalty is 10 minutes.
+# penalty: yes
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency

+#     penalty: yes            # the JOB's penalty
+#     autodetection_retry: 0  # the JOB's re-check interval in seconds
+#
+# Additionally to the above, gearman also supports the following:
+#
+#     hostname: localhost     # The host running the Gearman server
