+
+## Project Overview
+
+Daggy is a work orchestration framework for running workflows modeled as directed acyclic graphs (DAGs). It's designed for data processing pipelines where tasks have dependencies on each other.
+
+The system consists of several components:
+- **libdaggy**: Core library with DAG implementation, thread pool, task executors, and loggers
+- **daggyd**: REST server that receives and runs DAG specifications 
+- **daggyr**: Remote worker service that runs as a task executor
+- **utils/daggyc**: Command-line client
+- **webui**: Web interface for monitoring DAG execution
+
+## Build Commands
+
+### Prerequisites
+- cmake >= 3.14
+- gcc >= 8
+- npm (for the webui)
+- libslurm (optional)
+
+### Basic Build
+```sh
+# Create build directory
+mkdir -p build
+cd build
+
+# Configure with CMake
+cmake ..
+
+# Build
+make -j$(nproc)
+```
+
+### Build with Optional Features
+```sh
+# Enable Slurm support
+cmake -DDAGGY_ENABLE_SLURM=ON ..
+
+# Enable Redis support
+cmake -DDAGGY_ENABLE_REDIS=ON ..
+
+# Enable both features
+cmake -DDAGGY_ENABLE_SLURM=ON -DDAGGY_ENABLE_REDIS=ON ..
+```
+
+### Web UI
+```sh
+cd webui
+npm install
+npm run build
+```
+
+### Running Tests
+```sh
+# Run all tests
+cd build
+tests/tests
+
+# Run specific test case
+cd build
+tests/tests "[specific_test_tag]"
+```
+
+## Running the Application
+
+### Running daggyd with Web UI
+```sh
+build/bin/daggyd -v --assets-dir webui/dist
+```
+
+## Architecture
+
+Daggy uses a modular architecture consisting of:
+
+1. **DAG Core**: Implementation of directed acyclic graph data structure with task dependencies
+2. **Task Executors**: Different executors for running tasks:
+   - ForkingTaskExecutor (local execution)
+   - SlurmTaskExecutor (for HPC environments)
+   - DaggyRunnerTaskExecutor (for remote execution)
+   - SSHTaskExecutor (for SSH-based remote execution)
+   - NoopTaskExecutor (for testing)
+
+3. **State Loggers**: Track execution state
+   - OStreamLogger (in-memory state management)
+   - RedisLogger (persisting state to Redis)
+
+4. **Dynamic Task Features**:
+   - Task parameterization
+   - Runtime task generation
+
+Tasks are defined in JSON with dependencies specified via "parents" or "children" attributes, allowing complex workflow patterns.
