+# Flow Analyzer Engine
+
+Salesforce Code Analyzer engine named `flowAnalyzer`. It sends local `.flow` / `.flow-meta.xml` files to an org-backed Connect API and maps findings back onto the original XML.
+
+Analyze POST: `/services/data/v68.0/flowbuilder/flow-analyzer/analysis/metadata-archive` (`multipart/form-data` ZIP in `fileData`).
+
+This package does **not** replace the local Python `flow` engine.
+
+## Configuration
+
+```yaml
+engines:
+  flowAnalyzer:
+    target_org: myOrg
+```
+
+`target_org` is required. The CLI `--target-org` flag should populate it. The engine never falls back to the default Salesforce CLI org.
+
+## Commands
+
+```
+sf code-analyzer run --rule-selector flowAnalyzer --target-org myOrg
+sf code-analyzer rules --rule-selector flowAnalyzer --target-org myOrg
+```
