+# ACME Testing environment
+
+## Objectives
+
+In our integration ACME tests, we use a simulated Let's Encrypt container based stack named boulder.
+
+The goal of this directory is to provide to developers a Traefik-boulder full stack environment.
+This environment may be used in order to quickly test developments on ACME certificates management.
+
+The provided Boulder stack is based on the environment used during integration tests.
+
+## Directory content
+
+* **compose-acme.yml** : Docker-Compose file which contains the description of Traefik and all the boulder stack containers to get,
+* **acme.toml** : Traefik configuration file used by the Traefik container described above,
+* **manage_acme_docker_environment.sh**  Shell script which does all needed checks and manages the docker-compose environment.
+
+## Shell script
+
+### Description
+
+To work fine, boulder needs a domain name, with a related IP and storage file. The shell script allows to check the environment before launching the Docker environment with the rights parameters and to managing this environment.
+
+### Use
+
+The script **manage_acme_docker_environment.sh** requires one argument. This argument can have 3 values :
+
+* **--start** : Check environment and launch a new Docker environment.
+* **--stop** : Stop and delete the current Docker environment.
+* **--restart--** : Concatenate **--stop** and **--start** actions.
