# Documentation Status
Last updated: October 30, 2025
## Current State Summary
The documentation structure has been established with clear indicators of what's complete vs planned.
### Legend
- ✅ **Complete** - File exists with full content
- 📋 **Planned** - Mentioned in index but file doesn't exist yet
- 🚧 **In Progress** - File exists but needs expansion
---
## Getting Started (✅ Complete)
All essential getting-started guides are complete:
- ✅ `getting-started/installation.md` - Full installation guide
- ✅ `getting-started/quickstart.md` - Comprehensive tutorial with all three tiers
- ✅ `getting-started/vulkan-basics.md` - Complete Vulkan concepts guide
- ✅ `getting-started/choosing-a-tier.md` - Detailed tier comparison
- ✅ `getting-started/faq.md` - Extensive FAQ
- ✅ `getting-started/troubleshooting.md` - Comprehensive troubleshooting
**Status:** Ready for users ✅
---
## Guides (✅ Complete)
All tier guides are complete and professional:
- ✅ `guides/ez-tier-guide.md` - Complete EZ tier API walkthrough
- ✅ `guides/ex-tier-guide.md` - Complete EX tier guide (RuntimeManager, ShaderManager, PipelineBuilder)
- ✅ `guides/core-tier-guide.md` - Complete CORE tier documentation
- ✅ `guides/migration-guide.md` - Comprehensive migration patterns
**Status:** Ready for users ✅
**Content includes:**
- Philosophy and design principles
- Step-by-step tutorials
- Complete API coverage
- Working code examples
- Best practices
- Performance considerations
---
## Architecture (📋 Planned)
Directory needs to be created:
- 📋 `architecture/overview.md` - Project philosophy, design goals
- 📋 `architecture/three-tier-design.md` - Why three tiers, use cases
- 📋 `architecture/zero-cost-abstractions.md` - Performance guarantees, benchmarks
- 📋 `architecture/safety-guarantees.md` - Memory safety, Rust ownership
**Priority:** MEDIUM - Important for understanding design decisions
**Recommended content:**
- Pull from existing `md/` folder if relevant
- Focus on design decisions and trade-offs
- Include benchmark results from `benches/`
---
## API Reference (📋 Planned)
Directories need to be created:
- 📋 `api/core/` - 12 files (instance, device, queue, etc.)
- 📋 `api/ex/` - 6 files (runtime-manager, shader-manager, etc.)
- 📋 `api/ez/` - 3 files (ez-renderer, ez-frame, ez-config)
**Priority:** LOW - Users can use `cargo doc --open` for API docs
**Recommended approach:**
- Keep these as lightweight guides, not full API docs
- Focus on common usage patterns
- Link to rustdoc for detailed API
---
## Examples (📋 Planned)
Directory needs to be created:
- 📋 `examples/ez-examples.md` - Annotate existing `demos/ez/` code
- 📋 `examples/ex-examples.md` - Annotate existing `demos/ex/` code
- 📋 `examples/core-examples.md` - Annotate existing `demos/core/` code
**Priority:** MEDIUM-HIGH - Helps users understand demo code
**Recommended content:**
- Overview of each demo
- What concepts it demonstrates
- Line-by-line explanation of key parts
- When to use similar patterns
---
## Index Files (✅ Updated)
- ✅ `INDEX.md` - Updated with status indicators (✅/📋)
- ✅ `README.md` - Updated with status indicators and correct links
- ✅ Both files now clearly show what exists vs what's planned
---
## Recommended Next Steps
### Option 1: Complete Examples (High Value - Recommended)
Annotate existing demo code:
1. `examples/ez-examples.md` - Explain EZ demos
2. `examples/ex-examples.md` - Explain EX demos
3. `examples/core-examples.md` - Explain CORE demos
### Option 3: Create Architecture Docs (Medium Priority)
Document design decisions:
1. `architecture/overview.md` - Why shdrlib exists
2. `architecture/three-tier-design.md` - Design philosophy
3. `architecture/zero-cost-abstractions.md` - Performance story
4. `architecture/safety-guarantees.md` - Safety story
### Option 4: Minimal API Reference (Low Priority)
Light guides for common APIs (users have rustdoc):
1. Create directory structure
2. Add stub files pointing to rustdoc
3. Fill with usage examples over time

## Quick Commands
### View all documentation
```bash
# Start from the main docs README
cat docs/README.md
# Or view the full index
cat docs/INDEX.md
```
### Run existing demos
```bash
# EZ tier demos
cargo run --bin ez_01_hello_triangle
cargo run --bin ez_02_compute_multiply
cargo run --bin ez_03_buffers_demo
# EX tier demos
cargo run --bin ex_01_triangle_100_lines
cargo run --bin ex_02_compute_100_mul
cargo run --bin ex_03_textured_quad
# CORE tier demos
cargo run --bin 01_triangle_raw
cargo run --bin 02_compute_shader
cargo run --bin 05_custom_integration
```
### Generate API docs
```bash
cargo doc --open
```

## Notes
- **Getting Started** section is complete and ready for new users
- **Guides** are the highest priority missing content
- **Examples** documentation would add significant value
- **Architecture** docs help explain design decisions
- **API Reference** is lowest priority (rustdoc exists)
The current structure is solid - just needs content for the planned sections!
