+# BLAST DB Manager
+
+## Overview
+BLAST DB Manager is a tool designed to automate the creation and updating of BLAST (Basic Local Alignment Search Tool) databases. It utilizes GitHub Actions for workflow automation and runs on a self-hosted EC2 instance for enhanced control and customization.
+
+## Features
+- Automated BLAST database creation and updates
+- Integration with GitHub Actions for CI/CD
+- Custom runner setup on EC2 for specialized environment control
+- Slack notifications for job status updates
+- S3 synchronization for database storage and distribution
+
+## Prerequisites
+- An AWS account with EC2 and S3 access
+- A GitHub repository
+- Python 3.x installed on the EC2 instance
+- Poetry for Python dependency management
+- NCBI BLAST+ toolkit
+
+## Setup
+
+### 1. EC2 Instance Setup
+1. Launch an EC2 instance with Amazon Linux 2023.
+2. Install required software:
+   ```bash
+   sudo yum update -y
+   sudo yum install -y python3 python3-pip ncbi-blast+
+   pip3 install poetry
+   ```
+
+### 2. GitHub Actions Runner Setup
+1. On your GitHub repository, go to Settings > Actions > Runners.
+2. Click "New self-hosted runner" and follow the installation instructions for Linux.
+3. Start the runner on your EC2 instance:
+   ```bash
+   cd actions-runner
+   ./run.sh
+   ```
+
+### 3. Repository Setup
+1. Clone your repository on the EC2 instance.
+2. Create a `.github/workflows` directory in your repository.
+3. Add the `update_blast_db.yml` workflow file to this directory.
+
+### 4. Configuration
+1. Create a `config/blast_config.yaml` file in your repository with the necessary configuration for your BLAST DB creation.
+2. Set up the following secrets in your GitHub repository:
+   - `GITHUB_WEBHOOK_SECRET`
+   - `SLACK_TOKEN`
+   - `AWS_ACCESS_KEY_ID`
+   - `AWS_SECRET_ACCESS_KEY`
+
+## Usage
+
+### Running the Workflow
+The BLAST DB update workflow can be triggered in two ways:
+1. Automatically on push to the `main` branch.
+2. Manually from the Actions tab in your GitHub repository.
+
+### Workflow Steps
+1. Checkout the repository
+2. Set up Python and Poetry
+3. Install dependencies
+4. Ensure BLAST is installed
+5. Run the BLAST DB update script
+6. Upload logs as artifacts

+
+## Customization
+- Modify `src/create_blast_db.py` to adjust the BLAST DB creation process.
+- Update `config/blast_config.yaml` to change BLAST DB configurations.
+- Edit `.github/workflows/update_blast_db.yml` to alter the CI/CD workflow.
+
+## Troubleshooting
+- Check the GitHub Actions logs for detailed error messages.
+- Ensure the EC2 instance has the necessary permissions to access required AWS services.
+- Verify that all required secrets are correctly set in the GitHub repository settings.
