+# Introduction 
+
+
+The command chmod ug+x *.sh modifies file permissions for all shell script files in the current directory.
+Breaking it down:
+
+chmod - the command to change file permissions
+ug+x - the permission specification:
+
+u = user (file owner)
+g = group (users in the same group as the file)
++x = add execute permission
+
+
+*.sh - applies to all files ending with .sh (shell scripts)
+
+So this command gives execute permissions to both the file owner and group members for all shell script files in the current directory. After running this command, those .sh files can be executed directly (like ./script.sh) rather than needing to call them through an interpreter (like bash script.sh).
+This is commonly used when you have shell scripts that you want to make executable for yourself and others in your group.
+
+## Example Usage
+
+```bash
+chmod ug+x *.sh
+```

+# Introduction 
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+
+Following is a set of agentic rules to help Claude Code understand how to interact with this repository effectively:
+
+
+Create a file named `CLAUDE.md` in the root of the repository with the following content:
+
+```markdown
+
+```plaintext
+## Agentic Rules
+
+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Repository Status
+
+The repository is currently empty. Once code is added, this file should be updated to include:
+
+## Developer Commands
+- Build commands
+- Test commands
+- Lint/format commands
+- Development server commands
+
+## Architecture Overview
+
+- Project structure and organization
+- Key Design patterns and conversions
+- Important modules and their relationships
+- Configuration and setup requirements
+
+## Notes
+
+Update this file as the codebase evolves to help future Claude Code instances understand the project structure and development workflow.
+
+## Tasks
+
+1. First think through the problem, read the codebase for relevant files, and then write a plan.
+2. The plan should have a list of todo items that you can check off as you complete them
+3. Before you begin working, check in with me and I will verify the plan.
+4. Then, begin working on the todo items, marking them as complete as you go.
+5. Please every step of the way just give me a high level explanation of what changes you made.
+6. Make every task and code change you do as simple as possible. We want to avoid making any massive or complex changes. Every change should impact as little code as possible. Everything is about simplicity.
