-code0-flow is a Rust library developed by Code0 for managing flows within the FlowQueue and FlowStore. This libray is only for the internal usage of the execution block services (Aquila, Draco & Tarurs) and is not intendet to get used elsewhere.
+Internal Rust library for CodeZero execution services (Aquila, Draco, Taurus). It manages flow definitions, config helpers, and health checks.
 
 ## Features
 
-- `flow_definition` update the Adapter & Runtime definitions
-- `flow_config` base configuration for each service
-- `flow_health` provide health checks including NATS connectivity for readiness probes
+- `flow_definition` read flow definitions from a filesystem layout (per-feature folders with `data_type/`, `flow_type/`, `runtime_definition/` JSONs) with optional feature/version filtering
+- `flow_service` push definitions to Aquila via gRPC (depends on `flow_definition`)
+- `flow_config` env helpers and `.env` loading
+- `flow_health` tonic health service with NATS readiness
 
-## FlowStore
-
-### Keys
-
-The key in the FlowStore in a Store will always have the pattern:
-
-`flow_id::project_id::flow_type_identifier::<any_flow_type_specific_data>`
-
-E.g. for REST:
-
-`1::1::REST::test.code0.tech::GET`
-
-This would be a REST Flow identifier
-
-## FlowDefinition
-
-```rust
-// Define FlowType
-let flow_type = FlowType {
-    identifier: String::from("REST"),
-    settings: vec![],
-    input_type_identifier: Some(String::from("HTTP_REQUEST_OBJECT")),
-    return_type_identifier: Some(String::from("HTTP_RESPONSE_OBJECT")),
-    editable: true,
-    name: vec![Translation {
-        code: String::from("en-US"),
-        content: String::from("Rest Endpoint"),
-    }],
-    description: vec![Translation {
-        code: String::from("en-US"),
-        content: String::from("A REST API is a web service that lets clients interact with data on a server using standard HTTP methods like GET, POST, PUT, and DELETE, usually returning results in JSON format."),
-    }],
-};
-
-// Define DataTypes
-let data_type = DataType {
-    variant: 5,
-    name: vec![Translation {
-        code: String::from("en-US"),
-        content: String::from("HTTP Headers"),
-    }],
-    identifier: String::from("HTTP_HEADER_MAP"),
-    input_types: vec![],
-    return_type: None,
-    parent_type_identifier: Some(String::from("ARRAY")),
-    rules: vec![DataTypeRule {
-        config: Some(Config::ContainsType(DataTypeContainsTypeRuleConfig {
-            data_type_identifier: String::from("HTTP_HEADER_ENTRY"),
-        })),
-    }],
-}
-
-// Send to get updated in Sagittarius
-let update_client = code0_flow::flow_definition::FlowUpdateService::from_url(aquila_url)
-           .with_data_types(vec![data_type])
-           .with_flow_types(vec![flow_type]);
-
-// Response --> true if successfull
-update_client.send().await;
-```
-
-## FlowHealth
-
-```rust
-use code0_flow::flow_health::HealthService;
-use tonic_health::pb::health_server::HealthServer;
-
-// Create health service with NATS URL
-let health_service = HealthService::new("nats://localhost:4222".to_string());
-
-// Use with tonic gRPC server
-let health_server = HealthServer::new(health_service);
-
-// The service provides:
-// - "liveness" check: Always returns Serving (application is running)
-// - "readiness" check: Returns Serving only if NATS connection is healthy
-```
