 ## Quick start
 
 This image require the kernel module ip_vs loaded on the host (`modprobe ip_vs`) and need to be run with : --cap-add=NET_ADMIN --net=host
 
-    docker run --cap-add=NET_ADMIN --net=host -d osixia/keepalived
+    docker run --cap-add=NET_ADMIN --net=host -d osixia/keepalived:0.2.0
+
+## Beginner Guide
+
+### Use your own Keepalived config
+This image comes with a keepalived config file that can be easily customized via environment variables for a quick bootstrap,
+but setting your own keepalived.conf is possible. 2 options:
+
+- Link your config file at run time to `/container/service/keepalived/assets/keepalived.conf` :
+
+      docker run --volume /data/my-keepalived.conf:/container/service/keepalived/assets/keepalived.conf --detach osixia/keepalived:0.2.0
+
+- Add your config file by extending or cloning this image, please refer to the [Advanced User Guide](#advanced-user-guide)
+
+### Debug
+
+The container default log level is **info**.
+Available levels are: `none`, `error`, `warning`, `info`, `debug` and `trace`.
+
+Example command to run the container in `debug` mode:
+
+	docker run --detach osixia/keepalived:0.2.0 --loglevel debug
+
+See all command line options:
+
+	docker run osixia/keepalived:0.2.0 --help
+
 
 ## Environment Variables
 
-Environement variables defaults are set in **image/env.yaml**. You can modify environment variable values directly in this file and rebuild the image ([see manual build](#manual-build)). You can also override those values at run time with -e argument or by setting your own env.yaml file as a docker volume to `/container/environment/env.yaml`. See examples below.
+Environment variables defaults are set in **image/environment/default.yaml**
+
+See how to [set your own environment variables](#set-your-own-environment-variables)

+
 ### Set environment variables at run time :
 
 Environment variable can be set directly by adding the -e argument in the command line, for example :
 
-	docker run -e KEEPALIVED_INTERFACE="eno1" -e KEEPALIVED_PASSWORD="password!" \
-	-e KEEPALIVED_PRIORITY="100" -d osixia/keepalived
+	docker run --env KEEPALIVED_INTERFACE="eno1" --env KEEPALIVED_PASSWORD="password!" \
+	--env KEEPALIVED_PRIORITY="100" --detach osixia/keepalived
 
 Or by setting your own `env.yaml` file as a docker volume to `/container/environment/env.yaml`
 
-	docker run -v /data/my-env.yaml:/container/environment/env.yaml \
-	-d osixia/keepalived
+	docker run --volume /data/my-env.yaml:/container/environment/env.yaml \
+	--detach osixia/keepalived
+
+### Set your own environment variables
+
+#### Use command line argument
+Environment variables can be set by adding the --env argument in the command line, for example:
+
+    docker run --env KEEPALIVED_INTERFACE="eno1" --env KEEPALIVED_PASSWORD="password!" \
+    --env KEEPALIVED_PRIORITY="100" --detach osixia/keepalived:0.2.0
+
+
+#### Link environment file
+
+For example if your environment file is in :  /data/environment/my-env.yaml
+
+	docker run --volume /data/environment/my-env.yaml:/container/environment/01-custom/env.yaml \
+	--detach osixia/keepalived:0.2.0
+
+Take care to link your environment file to `/container/environment/XX-somedir` (with XX < 99 so they will be processed before default environment files) and not  directly to `/container/environment` because this directory contains predefined baseimage environment files to fix container environment (INITRD, LANG, LANGUAGE and LC_CTYPE).
+
+#### Make your own image or extend this image
+
+This is the best solution if you have a private registry. Please refer to the [Advanced User Guide](#advanced-user-guide) just below.

+### Extend osixia/keepalived:0.2.0 image
+
+If you need to add your custom TLS certificate, bootstrap config or environment files the easiest way is to extends this image.
