+# Testing devnet3 Configuration
+
+## Setup
+
+The local-devnet has been configured to test devnet3 features with the local zeam image.
+
+### Changes Made:
+
+1. **zeam-cmd.sh**: Updated to use `0xpartha/zeam:local` image
+2. **local-devnet/validator-config.yaml**: Added commented attestation_committee_count parameter
+
+## devnet3 Features Being Tested
+
+### 1. Automatic Aggregator Selection
+- One node will be randomly selected as aggregator on startup
+- The `isAggregator` flag in validator-config.yaml will be automatically updated
+- Only the selected aggregator will receive `--is-aggregator` flag
+
+### 2. Optional Attestation Committee Count
+- Currently commented out (clients use hardcoded default)
+- Can be enabled by uncommenting: `attestation_committee_count: 1`
+- When set, all clients receive `--attestation-committee-count <value>` flag
+
+## Test Commands
+
+### Basic Test - Single Node (zeam_0)
+```bash
+# Run the test script
+./test-local-zeam.sh
+
+# Or manually:
+NETWORK_DIR=local-devnet ./spin-node.sh --node zeam_0 --generateGenesis --cleanData
+```
+
+### Test with Manual Aggregator Selection
+```bash
+# Specify zeam_0 as aggregator
+NETWORK_DIR=local-devnet ./spin-node.sh --node zeam_0 --generateGenesis --cleanData --aggregator zeam_0
+```
+
+### Test Multiple Nodes
+```bash
+# Run all nodes (zeam_0 will be randomly selected as aggregator)
+NETWORK_DIR=local-devnet ./spin-node.sh --node all --generateGenesis --cleanData
+
+# Run specific nodes with zeam_0 as aggregator
+NETWORK_DIR=local-devnet ./spin-node.sh --node "zeam_0 ream_0" --generateGenesis --cleanData --aggregator zeam_0
+```
+
+### Test with Attestation Committee Count Override
+```bash
+# 1. Uncomment attestation_committee_count in local-devnet/genesis/validator-config.yaml
+# 2. Set desired value (e.g., attestation_committee_count: 4)
+# 3. Run:
+NETWORK_DIR=local-devnet ./spin-node.sh --node zeam_0 --generateGenesis --cleanData
+```
+
+## Expected Behavior
+
+### Aggregator Selection
+1. Script displays: "Randomly selected aggregator: zeam_0 (index 0 out of 7 nodes)" OR "Using user-specified aggregator: zeam_0"
+2. Script updates validator-config.yaml: sets `isAggregator: true` for selected node
+3. parse-vc.sh output shows: "Is Aggregator: true" for aggregator, "false" for others
+4. zeam command includes `--is-aggregator` flag for aggregator only
+
+### Attestation Committee Count
+**When NOT set (default):**
+- parse-vc.sh does NOT display "Attestation Committee Count"
+- zeam command does NOT include `--attestation-committee-count` flag
+- Client uses its hardcoded default
+
+**When set (e.g., to 4):**
+- parse-vc.sh displays: "Attestation Committee Count: 4"
+- zeam command includes: `--attestation-committee-count 4`
+- Client uses the specified value
+
+## Verification
+
+### Check Docker Container
+```bash
+# Inspect the running container
+docker inspect zeam_0
+
+# Check container logs
+docker logs zeam_0
+
+# Verify command-line arguments
+docker inspect zeam_0 | grep -A20 Args
+```
+
+### Check Configuration
+```bash
+# Verify aggregator selection in validator-config.yaml
+yq eval '.validators[] | select(.name == "zeam_0") | .isAggregator' local-devnet/genesis/validator-config.yaml
+
+# Check all aggregators
+yq eval '.validators[] | select(.isAggregator == true) | .name' local-devnet/genesis/validator-config.yaml
+```
+
+### Monitor Node Output
+```bash
+# Watch zeam_0 logs in real-time
+docker logs -f zeam_0
+
+# Check for aggregator-related messages
+docker logs zeam_0 2>&1 | grep -i aggregat
+```
+
+## Cleanup
+
+```bash
+# Stop and remove zeam_0 container
+docker rm -f zeam_0
+
+# Stop all nodes
+NETWORK_DIR=local-devnet ./spin-node.sh --node all --stop
+
+# Clean data directories
+rm -rf local-devnet/data/*
+```
+
+## Troubleshooting
+
+### Image Not Found
+If you get "image not found" error:
+```bash
+# Check if image exists
+docker images | grep zeam
+
+# Pull/build the image if needed
+# (build instructions depend on your zeam setup)
+```
+
+### Port Conflicts
+If ports are already in use:
+```bash
+# Check what's using the port
+lsof -i :8081  # zeam_0 metrics port
+lsof -i :9001  # zeam_0 QUIC port
+
+# Kill conflicting processes or change ports in validator-config.yaml
+```
+
+### Genesis Generation Fails
+```bash
+# Ensure yq is installed
+brew install yq  # macOS
+# or follow: https://github.com/mikefarah/yq#install
+
+# Check validator-config.yaml syntax
+yq eval . local-devnet/genesis/validator-config.yaml
+```
+
+## Notes
+
+- The `0xpartha/zeam:local` image should have the latest devnet3 changes
+- All devnet3 features (aggregator selection, optional attestation_committee_count) are enabled
+- The configuration is set up for local testing with 127.0.0.1 IPs
+- Hash-sig keys will be generated automatically on first run with `--generateGenesis`
