+# Crowdsec Bouncer Traefik plugin
+
+This plugins aims to implement a Crowdsec Bouncer into a traefik plugin
+
+## Usage
+
+
+### Configuration
+
+For each plugin, the Traefik static configuration must define the module name (as is usual for Go packages).
+
+The following declaration (given here in YAML) defines a plugin:
+
+```yaml
+# Static configuration
+
+experimental:
+  localPlugins:
+    bouncer:
+      moduleName: github.com/maxlerebourg/crowdsec-bouncer-traefik-plugin
+```
+
+```yaml
+# Dynamic configuration
+
+http:
+  routers:
+    my-router:
+      rule: host(`woami.localhost`)
+      service: service-foo
+      entryPoints:
+        - web
+      middlewares:
+        - my-plugin
+
+  services:
+    service-foo:
+      loadBalancer:
+        servers:
+          - url: http://127.0.0.1:5000
+  
+  middlewares:
+    crowdsec:
+      plugin:
+        bouncer:
+          enabled: true
+          crowdseclapikey: 40796d93c2958f9e58345514e67740e5
+```
+
+### Local Mode
+
+Traefik also offers a developer mode that can be used for temporary testing of plugins not hosted on GitHub.
+To use a plugin in local mode, the Traefik static configuration must define the module name (as is usual for Go packages) and a path to a [Go workspace](https://golang.org/doc/gopath_code.html#Workspaces), which can be the local GOPATH or any directory.
+
+The plugins must be placed in `./plugins-local` directory,
+which should be in the working directory of the process running the Traefik binary.
+The source code of the plugin should be organized as follows:
+
+```
+./plugins-local/
+    └── src
+        └── github.com
+            └── maxlerebourg
