+## Description
+
+Deploy [Fluent-bit](https://github.com/fluent/fluent-bit) using ansible.
+
+### Requirements
+
+Role expects to be provided with the following information:
+* `fluentbit_main_config` - the main Fluent-bit configuration
+
+### Example
+Minimum Fluent-bit config that will send a test log, filter it, and output to stdout.
+
+```yaml
+fluentbit_main_config:
+  service:
+    flush: 5
+    log_level: info
+
+parsers:
+    - name: json
+      format: json
+      time_key: time
+      time_format: '%d/%b/%Y:%H:%M:%S %z'
+
+  pipeline:
+    inputs:
+        - name: dummy
+          dummy: '{"endpoint":"localhost", "value":"something"}'
+          tag: dummy
+    filters:
+        - name: grep
+          match: '*'
+          logical_op: or
+          regex:
+            - value something
+            - value error
+    outputs:
+        - name: stdout
+
+```
+
+For more details on setting up the Fluent-bit config, refer to official documentation:

 Installs and configures the PHP-FPM flavour of FastCGI.
 
+Note, for legacy reasons this role sets up PHP-FPM to use TCP/IP instead of a Unix socket by default. However, we *recommend* you change this by setting `unix_socket: true` unless you really need to run PHP-FPM over TCP/IP, as a Unix socket is much faster. If you do, be sure to set the `pool_group` variable to match your web server user, or the web server will be unable to interact with PHP.
