+Code for exporting data from ArchivesSpace to ArcLight, along with additional utility scripts for data handling and transformation.
+
+## Quick Start
+
+This directory contains a complete, working installation of arcflow with creator records support. To run it:
+
+```bash
+# 1. Install dependencies
+pip install -r requirements.txt
+
+# 2. Configure credentials
+cp .archivessnake.yml.example .archivessnake.yml
+nano .archivessnake.yml  # Add your ArchivesSpace credentials
+
+# 3. Run arcflow
+python -m arcflow.main \
+  --arclight-dir /path/to/your/arclight-app \
+  --aspace-dir /path/to/your/archivesspace \
+  --solr-url http://localhost:8983/solr/blacklight-core \
+  --aspace-solr-url http://localhost:8983/solr/archivesspace
+```

+
+## Features
+
+- **Collection Indexing**: Exports EAD XML from ArchivesSpace and indexes to ArcLight Solr
+- **Creator Records**: Extracts creator agent information and indexes as standalone documents
+- **Biographical Notes**: Injects creator biographical/historical notes into collection EAD XML
+- **PDF Generation**: Generates finding aid PDFs via ArchivesSpace jobs
+- **Incremental Updates**: Supports modified-since filtering for efficient updates
+
+## Creator Records
+
+ArcFlow now generates standalone creator documents in addition to collection records. Creator documents:
+
+- Include biographical/historical notes from ArchivesSpace agent records
+- Link to all collections where the creator is listed
+- Can be searched and displayed independently in ArcLight
+- Are marked with `is_creator: true` to distinguish from collections
+- Must be fed into a Solr instance with fields to match their specific facets (See: Configure Solr Schema below)
+
+### Agent Filtering
+
+**ArcFlow automatically filters agents to include only legitimate creators** of archival materials. The following agent types are **excluded** from indexing:
+
+- ✗ **System users** - ArchivesSpace software users (identified by `is_user` field)
+- ✗ **System-generated agents** - Auto-created for users (identified by `system_generated` field)
+- ✗ **Software agents** - Excluded by not querying the `/agents/software` endpoint
+- ✗ **Repository agents** - Corporate entities representing the repository itself (identified by `is_repo_agent` field)
+- ✗ **Donor-only agents** - Agents with only the 'donor' role and no creator role
+
+**Agents are included if they meet any of these criteria:**
+
+- ✓ Have the **'creator' role** in linked_agent_roles
+- ✓ Are **linked to published records** (and not excluded by filters above)
+
+This filtering ensures that only legitimate archival creators are discoverable in ArcLight, while protecting privacy and security by excluding system users and donors.
+
+### How Creator Records Work
+
+1. **Extraction**: Agent data is exported from ArchivesSpace for use in creator records
+2. **Filtering**: Creator vs. non-creator agents are determined via Solr queries built from `_get_target_agent_criteria()` and `_get_nontarget_agent_criteria()`, which exclude system users, donors, and other non-creator agents  
+3. **Processing**: For each target creator agent, ArcFlow generates an EAC-CPF XML document that includes bioghist notes
+4. **Linking**: Handled via Solr using the persistent_id field (agents and collections linked through bioghist references)
+5. **Indexing**: Creator XML files are indexed to Solr using `traject_config_eac_cpf.rb`
+
+### Creator Document Format
+
+Creator documents are stored as XML files in `agents/` directory using the ArchivesSpace EAC-CPF export:
+
+```xml
+<?xml version="1.0" encoding="UTF-8"?>
+<eac-cpf xml:lang="eng" xmlns="urn:isbn:1-931666-33-4" xmlns:html="http://www.w3.org/1999/xhtml" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:isbn:1-931666-33-4 https://eac.staatsbibliothek-berlin.de/schema/cpf.xsd">

+
+### Indexing Creator Documents
+
+#### Configure Solr Schema (Required Before Indexing)
+
+⚠️ **CRITICAL PREREQUISITE** - Before you can index creator records to Solr, you must configure the Solr schema.
+
+**See [SOLR_SCHEMA.md](SOLR_SCHEMA.md) for complete instructions on:**
+- Which fields to add (is_creator, creator_persistent_id, etc.)
+- Three methods to add them (Schema API recommended, managed-schema, or schema.xml)
+- How to verify they're added
+- Troubleshooting "unknown field" errors
+
+**Quick Schema Setup (Schema API method):**
+```bash
+# Add is_creator field
+curl -X POST -H 'Content-type:application/json' \
+  http://localhost:8983/solr/blacklight-core/schema \
+  -d '{"add-field": {"name": "is_creator", "type": "boolean", "indexed": true, "stored": true}}'
+
+# Add other required fields (see SOLR_SCHEMA.md for complete list)
+```
+
+**Verify schema is configured:**
+```bash
+curl "http://localhost:8983/solr/blacklight-core/schema/fields/is_creator"
+# Should return field definition, not 404
+```
+
+⚠️ **If you skip this step, you'll get:**
+```
+ERROR: [doc=creator_corporate_entities_584] unknown field 'is_creator'
+```
+
+This is a **one-time setup** per Solr instance.
+
+---
+
+### Traject Configuration for Creator Indexing
+
+The `traject_config_eac_cpf.rb` file defines how EAC-CPF creator records are mapped to Solr fields.
+
+**Search Order**: arcflow searches for the traject config following the collection records pattern:
+1. **arcuit_dir parameter** (if provided via `--arcuit-dir`) - Highest priority, most up-to-date user control
+2. **arcuit gem** (via `bundle show arcuit`) - For backward compatibility when arcuit_dir not provided
+3. **example_traject_config_eac_cpf.rb** in arcflow - Fallback for module usage without arcuit
+
+**Example File**: arcflow includes `example_traject_config_eac_cpf.rb` as a reference implementation. For production:
+- Copy this file to your arcuit gem as `traject_config_eac_cpf.rb`, or
+- Specify the location with `--arcuit-dir /path/to/arcuit`
+
+**Logging**: arcflow clearly logs which traject config file is being used when creator indexing runs.
+
+To index creator documents to Solr manually:
+
+```bash
+bundle exec traject \
+  -u http://localhost:8983/solr/blacklight-core \
+  -i xml \
+  -c traject_config_eac_cpf.rb \
+  /path/to/agents/*.xml
+```
+
+Or integrate into your ArcFlow deployment workflow.
+
