 The recommanded mode for performance is the streaming mode, decisions are updated every 60 sec by default and that's the only communication between traefik and crowdsec. Every requests that happens hits the cache for quick decisions.
 
 ## Usage
 
+To get started, use the `docker-compose.yml` file.
+
+You can run it with:
+```bash
+make run
+```
+
+### Note
+Each middleware in traefik has it's own data and is instanciated by service.
+This means if there are 10 services protected by the bouncer in streaming alone or live mode, the cache will be duplicated to all 10 services.
+This is because traefik does not allow plugins to store data locally that can be consummed.
+
+The synchronisation with the crowdsec service will happen also 10 times in the period selected.
+It should be taken into account when fixing this period so each middleware has time to sync data from crowdsec.
+
+At each start of synchronisation, the middleware will wait a random number of seconds to avoid simultaneous calls to crowdsec.

 ### About
 
-Me and [mhanotaux](https://github.com/mhanotaux) have been using traefik since 2020 at [Primadviz](https://primadviz.com).
+Me and [mathieuHa](https://github.com/mathieuHa) have been using traefik since 2020 at [Primadviz](https://primadviz.com).
 We come from web developper and security engineer background and wanted to add the power of a very promesing technology (Crowdsec) into the edge router we love.
 
 We initially run into this project: https://github.com/fbonalair/traefik-crowdsec-bouncer
