-== Overview
+== Deliverable
 
-Modshells transforms monolithic shell configuration files (`.bashrc`, `.zshrc`, etc.) into a modular directory structure. Instead of maintaining a single, sprawling configuration file, Modshells organises configurations into logical categories that are automatically sourced.
+**Modshells** is a command-line tool that transforms monolithic shell configuration files into a modular, maintainable directory structure. The tool:
 
-=== The Problem
+1. **Creates** a standardised directory hierarchy for shell configurations
+2. **Detects** installed shells on your system (Bash, Zsh, Fish, Nushell, and 6 others)
+3. **Injects** sourcing logic into shell configuration files (with backup)
+4. **Ensures idempotency** - safe to run multiple times without side effects
 
-Traditional shell configuration becomes unwieldy:
+=== Current Status
 
-* Single files grow to hundreds of lines
-* Related configurations scattered throughout
-* Difficult to share configurations across shells
-* No clear separation of concerns
-* Risky manual editing of critical dotfiles

+|===
+| Aspect | Status
+
+| Directory creation | Working
+| Shell detection | Stub (returns hardcoded list)
+| Config backup | Not implemented
+| Source injection | Not implemented
+|===
 
-=== The Solution
+*This is alpha software.* The core architecture is complete, but the primary feature (modularising shell configs) is not yet functional. See <<Development Status>> for details.
 
-Modshells creates a standardised modular structure:
+=== What You Get
+
+After running `modshells`, your shell configurations are organised into:

-Each directory contains shell-agnostic or shell-specific configuration snippets that are automatically sourced in order.
+Each shell's config file (`.bashrc`, `.zshrc`, etc.) sources these directories automatically. Add a new alias? Drop a file into `misc/`. OS-specific tweak? Put it in `os/`. Done.
