+# API d'administration
+
+## Authentification
+
+L'ensemble des appels aux APIs HTTP du service `bouncer-admin` sont authentifiées via l'utilisation d'un jeton [JWT](https://datatracker.ietf.org/doc/html/rfc7519) signé par la clé privée du serveur.
+
+Le jeton d'accès doit être transmis avec l'ensemble des appels aux points d'entrée via l'entête HTTP `Authorization` en respectant la forme suivante:
+
+```
+Authorization: Bearer <jwt>
+```
+
+### Génération d'un jeton d'authentification
+
+La génération d'un jeton d'authentification s'effectue via la commande suivante:
+
+```shell
+bouncer auth create-token --subject "<subject>" --role "<role>"
+```
+
+Où:
+
+- `"<subject>"` est une chaîne de caractère arbitraire ayant pour objectif d'identifier de manière unique l'utilisateur associé au jeton;
+- `"<role>"` peut prendre une des deux valeurs `reader` ou `writer` correspondant aux droits suivants respectifs:
+    - droit en lecture sur l'ensemble des entités (proxy, layer);
+    - droit en lecture ET en écriture sur l'ensemble des entités.
+
+
+## Points d'entrée

+## Description

+Ce layer permet de bloquer l'accès à un site (ou une section de celui ci) ciblé par un proxy.
+
+## Type
+
+`circuitbreaker`
+
+## Options
+
+### `authorizedCIDRs`
+
+- **Type:** `[]string`
+- **Valeur par défaut:** `[]`
+- **Description:** Autoriser les adresses distantes contenues dans un des masques réseau (en notation ["CIDR"](https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing#CIDR_notation) définis à contourner la restriction d'accès.
+
+### `matchURLs`
+
+- **Type:** `[]string`
+- **Valeur par défaut:** `["*"]`
+- **Description:** Limiter l'action du layer à cette liste de patrons d'URLs. 
+
+    Par exemple, si vous souhaitez limiter votre restriction d'accès à l'ensemble d'une section "`/blog`" d'un site, vous pouvez déclarer la valeur `["*/blog*"]`. Les autres URLs du site ne seront pas affectées par la restriction.
+
+### `templateBlock`
+
+- **Type:** `string`
+- **Valeur par défaut:** `"default"`
+- **Description:** Bloc du template HTML pour effectuer le rendu de la page indiquant la restriction d'accès.
+
+    Voir le [fichier de configuration de référence](../../../../misc/packaging/common/config.yml), section `layers.circuitbreaker` pour voir les options permettant de personnaliser le chemin du répertoire contenant les templates.

+# Métriques
+
+Bouncer expose un certain nombre de métriques Prometheus sur le serveur proxy ainsi que sur le serveur d'administration. Ces métriques sont par défaut accessibles sur `/.bouncer/metrics`. 
+
+Il est possible de configurer le point d'entrée de ces métriques ainsi que d'ajouter une authentification de type `Basic Auth` [via la configuration](../../../misc/packaging/common/config.yml) (voir les clés `admin.metrics` et `proxy.metrics`).
+
+Outre les métriques par défaut fournies par la librairie [Prometheus](https://prometheus.io/docs/guides/go-application/#instrumenting-a-go-application-for-prometheus), les serveurs Bouncer exposent également des métriques propres.
+
+Chaque layer associé à un proxy peut également ses propres métriques spécifiques. [Voir la page de documentation](./layers/README.md) de chaque layer pour plus d'informations.
+
+## Métriques spécifiques

+### Serveur proxy
