+- [docker tips][5]
+
+This Image provide a Linux Ubuntu LTS distribution with :
+- fully functionnal & colorized terminal
+- bash
+- curl
+- nano as editor
+
+Base image : [ubuntu](https://hub.docker.com/_/ubuntu/)
+
+This project come with a structure to facilitate further images (like pluie/libyaml)
+
+## Image Size
+
+- very small image ~ 9 MB
+
+
+## Image Usage
+
+```
+$ docker run --name ubuntu -it pluie/ubuntu
+```
+
+## Image Structure
+
+```
+project/
+   |
+   |-- install.d/   # deployed in /scripts on target container
+   |      |         # launch on docker image building process
+   |      |         # XX-name.sh - low XX are run first
+   |      |-- 00-util.sh
+   |      |-- 40-fix.sh
+   |
+   |-- pre-init.d/  # deployed in /scripts on target container
+   |      |         # launch on docker container running process
+   |      |-- 50-builder.sh
+   |
+   |-- build        # build docker image : ./build [TAG]
+   |-- common.sh    # don't modify - sourced by main.sh to execute pre-init.d scripts first
+   |-- install.sh   # don't modify - execute install.d scripts on docker building process
+   |-- main.sh      # source common.sh then execute entry point instruction
+   |-- util.sh      # sourced by common.sh
+```
+
+you can easily create your own images based on this structure.  
+keep an eye to pluie/libyalm wich extend pluie/ubuntu
+
+
+## Extend pluie/ubuntu Image
+
+RUN instructions are minimized  
+on extended image you only need to use :
+```
+RUN bash /scripts/install.sh
+```
+add your packages in a script in install.d directory  
+keep name below 40 because install.d/40-fix.sh clean package repository  
+each extended image inherit install.d && pre-init.d scripts
+
+extended images doesn't need to define ENTRYPOINT  
+you can keep intact build script in each extended project  
+manage your install & init instruction in install.d & pre-init.d directory  
+and write your own main.sh script
