+# Certbot ansible role
+
+Install certbot for debian and request certificats.
+
+This role is part of my ansible roles. It is made to interact with other roles that are listed here, and require some variables.
+
+In particular, the `nginx` role allows to proxy the request from a machine cut from the internet to the LE server.
+
+## Role required:
+
+- `nginx`: https://gitea.auro.re/Pains-Perdus/nginx.git
+
+## Variable required:
+
+```
+ip_LE_proxy: str, optionnal, the IP of the proxy to LE
+certbot_certs:
+  `domaine_name`:
+    links: str[], list of links pointing to the certificate/key (the keychain link will be suffixed by `.crt`, the key by `.key`)
+    hooks: str[], optional, list of commands to run after renewing the certificat
+```
+
+`certbot_certs` is a dictionnary, where the keys are the domaine names for the certificates.
+
+## Optionnal variables
+
+```
+http_sites: dictionnary of sites, used by the nginx role
+```
+
+## Add role to you ansible playbook:
+
+To add this role to your project, you can use git submodules: 
+
+```
+git submodule add ssh://git@gitea.auro.re:2222/Pains-Perdus/certbot.git roles/certbot
+git submodule init
+```
+
+## Http Sites
+
+The variable `http_sites` is a dictionnary of the http site managed by nginx. The additionnal (and optionnal) field `use_certbot` can be added to the variable of a site so that certbot generat its certificate.
+
+```
+http_sites:
+  `server_name`:
+    ...
+    use_certbot: bool, optionnal (default false), if set to true, add an entry to `certbot_certs` automagically.
+```
