+## Analytics Configuration
+
+Analytics is powered by Logflare, a centralized logging and analytics platform.
+It requires a PostgreSQL database for storing analytics data.
+
+```rust
+Analytics::default()
+    .with_postgres_backend_url("postgresql://...")    // PostgreSQL backend URL (required)
+    .with_postgres_backend_schema("_analytics")       // Backend schema
+    .with_db_hostname("localhost")                    // Database hostname
+    .with_db_port(5432)                               // Database port
+    .with_db_username("supabase_admin")               // Database username
+    .with_db_password("password")                     // Database password
+    .with_db_database("_supabase")                    // Database name
+    .with_public_access_token("your-public-token")   // Public API token
+    .with_private_access_token("your-private-token") // Private API token
+    .with_encryption_key("base64-key...")             // Encryption key for sensitive data
+    .with_single_tenant(true)                         // Single-tenant mode
+    .with_supabase_mode(true)                         // Supabase integration mode
+    .with_log_level("warn")                           // Log verbosity
+    .with_tag("1.26.13")                              // Image version
+    .with_env("KEY", "value")                         // Custom environment variable
