+# zppy Integration Test Automation
+
+This automation system streamlines the zppy integration testing workflow, reducing manual steps and wait time while maintaining quality control checkpoints.
+
+## Quick Start
+
+### Basic Usage (Interactive Mode)
+```bash
+./run_integration_test.bash
+```
+
+## Workflow Phases
+
+### Phase 1: Setup
+- Sets up e3sm_diags conda environment
+- Sets up zppy-interfaces conda environment
+- Sets up zppy conda environment
+- Generates config files
+- Submits initial SLURM jobs (6 configs)
+- Waits for jobs to complete
+
+### Phase 2: Bundles Part 2
+- Checks status of bundles runs
+- Submits bundles part 2 jobs
+- Waits for completion
+
+### Phase 3: Validation
+- Checks all status files
+- Runs pytest integration tests:
+  - test_bash_generation.py
+  - test_campaign.py
+  - test_defaults.py
+  - test_last_year.py
+  - test_bundles.py
+- Provides instructions for running test_images.py on compute node
+
+## Output and Logs
+
+The script provides color-coded output:
+- 🔵 **Blue**: Informational messages
+- 🟢 **Green**: Success messages
+- 🟡 **Yellow**: Warnings and checkpoints
+- 🔴 **Red**: Errors
+
+### SLURM Job Monitoring
+The script automatically monitors SLURM jobs and shows:
+```
+Jobs remaining: 42 (elapsed: 1234s)
+```
+
+### Status File Checking
+Automatically checks for errors in status files:
+```
+✓ v2: No errors found
+✓ Legacy v2: No errors found
+✓ v3: No errors found
+...
+```
+
+## Customization
+
+### Modify Test Configurations
+
+Edit the script to change which configs are run:
+
+```bash
+# In the generated Python code section, modify:
+"cfgs_to_run": [
+    "weekly_bundles",
+    "weekly_comprehensive_v2",
+    # Add or remove configs here
+],
+```
+
+### Adjust Timeouts
+
+```bash
+# In phase_1_setup(), change max wait time:
+wait_for_slurm_jobs 30 14400  # 30s interval, 4hr max
+
+# In phase_2_bundles_part2():
+wait_for_slurm_jobs 30 3600   # 30s interval, 1hr max
+```
+
+## Troubleshooting
+
+### Script Exits Early
+Check the error message. The script uses `set -e`, so it exits on any error.
+
+### Jobs Don't Complete
+- Check SLURM queue: `squeue -u <user>`
+- Check job logs in the output directories
+- Increase timeout: edit `wait_for_slurm_jobs` calls
+
+### Environment Issues
+```bash
+# Clean and rebuild
+conda remove --y --all --name test-diags-main-YYYYMMDD
+conda remove --y --all --name test-zi-main-YYYYMMDD
+conda remove --y --all --name test-zppy-main-YYYYMMDD
+
+# Check configurations and then re-run
+./run_integration_test.bash
+```

+
+## Example run
+
+```bash
+# The script WILL change branches and MAY cancel jobs.
+# For safety, confirm branches have no uncommitted changes beforehand:
+cd ~/ez/e3sm_diags
+git status
+cd ~/ez/zppy-interfaces
+git status
+cd ~/ez/zppy
+git status
+# For safety, confirm no jobs are currently running:
+squeue -u <user>
+
+cd /home/ac.forsyth2/ez/zppy_main_branch_tests/test_20260126
+cp ~/ez/zppy/tests/main_branch_testing/* . # Copy, so the script isn't affected by the branch change
+emacs run_integration_test.bash # Configure parameters
+
+screen # Run on screen
+cd /home/ac.forsyth2/ez/zppy_main_branch_tests/test_20260126 # If not there already
+# Bypass manual checkpoints, tee output:
+time ./run_integration_test.bash --date 20260126_run1 --auto 2>&1 | tee integration_test.log
+# CTRL A D to exit screen
+screen -ls # Check which node the screen is on.
+tail -f integration_test.log # Follow log updates
