+# Fluent Bit
+
+[Fluent Bit](https://fluentbit.io/) is a lightweight and high performance log processor.
+In this repository you will find the container images ready for production usage.
+Our stable images are based in [Distroless](https://github.com/GoogleContainerTools/distroless) focusing on security containing just the Fluent Bit binary, minimal system libraries and basic configuration.
+
+Optionally, we provide debug images which contain shells and tooling that can be used to troubleshoot or for testing purposes.
+
+For a detailed list of tags and versions available, please refer to the the official documentation:
+
+<https://docs.fluentbit.io/manual/installation/docker>
+
+## Getting Started
+
+Run a Fluent Bit instance that will receive messages over TCP port 24224 through the [Forward](https://docs.fluentbit.io/manual/pipeline/outputs/forward) protocol, and send the messages to the STDOUT interface in JSON format every second:
+
+```shell
+docker run -p 127.0.0.1:24224:24224 fluent/fluent-bit /fluent-bit/bin/fluent-bit -i forward -o stdout -p format=json_lines -f 1
+```
+
+Now run a separate container that will send a test message.
+This time the Docker container will use the Fluent Forward Protocol as the logging driver:
+
+```shell
+docker run --log-driver=fluentd -t ubuntu echo "Testing a log message"
+```
+
+On Fluent Bit container, it will print to stdout something like this:
+
+```shell
