 ## Usage
 
+### Environment variables
+
+Use `.env.example` as reference. For conversation cache behavior in Redis, you can control it with one switch:
+
+- Global: `CONVERSATION_CACHE_ENABLED=true|false`
+- TTL de conversaciones: `CONVERSATION_HISTORY_TTL=2629800` (seconds; default 2629800 = 1 month)
+- Provider overrides:
+  - `OPENAI_CONVERSATION_CACHE_ENABLED=true|false`
+  - `GEMINI_CONVERSATION_CACHE_ENABLED=true|false`
+  - `OLLAMA_CONVERSATION_CACHE_ENABLED=true|false`
+
+Priority order:
+
+1. Provider-specific variable
+2. Global variable
+3. Default value (`true`)
+
