+AxoSyslog started as a syslog-ng fork [[1]](#r1), branched off at v4.7.1 of
+syslog-ng with the following focus:
+  * cloud native (containers, helm charts, kubernetes integration),
+  * performance (eBPF, memory allocator, etc),
+  * security data tailored parsing and transformation (filterx, app-parser, app-transform, etc)
+
+This repository contains the AxoSyslog source tree, container images, and Helm charts
 created and maintained by [Axoflow](https://axoflow.com).

+
+## Quick-start
+
+To start using AxoSyslog, you can use one of these
+deployment mechanisms:
+  - pure containers (docker, podman)
+  - Helm charts (Kubernetes)
+  - packages (deb, rpm, etc)
+
+Once the binaries are deployed, create a configuration file called 
+`/etc/syslog-ng/syslog-ng.conf`, which will then be processed by
+the `syslog-ng` process.
+
+A simple example is to ingest syslog traffic on tcp/514 and write it to a
+file:
+
+```
+@version: 4.7
+@include "scl.conf"
+
+log {
+	source {
+		system();
+		network();
+	};
+	destination { file("/var/log/syslog"); };
+};
+```
+
+You can find more examples in the [Quickstart section of the
+documentation](https://axoflow.com/docs/axosyslog-core/quickstart/).

-### Difference from upstream images
-
-Our images are different from the [upstream syslog-ng images](https://hub.docker.com/r/balabit/syslog-ng/) in a number of ways:
-
-- They are based on Alpine Linux, instead of Debian testing for reliability and smaller size (thus smaller attack surface).
-- They incorporate cloud-native features and settings (such as the Kubernetes source).
-- They incorporate container-level optimizations (like the use of an alternative malloc library) for better performance and improved security.
-- They support the ARM architecture.
+The container images contain a default configuration file which you probably
+want to customize. Read more about using these images [directly via
+podman/docker](https://axoflow.com/docs/axosyslog-core/install/podman-systemd/)

 ## Documentation
 
 You can find [comprehensive documentation for AxoSyslog](https://axoflow.com/docs/axosyslog-core)
 on the [Axoflow website](https://axoflow.com/).
 
-The documentation is a combination of the syslog-ng reference guide and the
-AxoSyslog reference guide.  The [syslog-ng documentation](https://axoflow.com/docs/axosyslog-core)
-was included in there as the upstream documentation fell out of maintenance.
+## Difference from syslog-ng
+
+The original founder of syslog-ng forked off AxoSyslog from the original
+syslog-ng after the 4.7.1 release. AxoSyslog is a drop in replacement, retaining
+the original license, release schedule and processes.
