+# Contributing to LeaksLab
+
+Thank you for helping grow the most complete AI system prompt library on GitHub.
+
+## What We Accept
+
+### High Priority
+- **New AI tool system prompts** not yet in the library
+- **Updated versions** of existing prompts (tools update frequently)
+- **Tool schemas** (JSON function/tool definitions used by AI agents)
+- **Model configurations** (context window, temperature settings, model identifiers)
+
+### Also Accepted
+- Fixes to formatting or encoding issues
+- Better organization within existing directories
+- Additional analysis or documentation for existing tools
+
+### Not Accepted
+- Proprietary code, weights, or model binaries
+- Content that violates a tool's Terms of Service in a harmful way
+- Fabricated or AI-generated "fake" prompts
+- Duplicate content without clear differentiation
+
+---
+
+## How to Contribute
+
+### 1. Fork the Repository
+
+```bash
+git clone https://github.com/VoXc2/system-prompts-and-models-of-ai-tools.git
+cd system-prompts-and-models-of-ai-tools
+```
+
+### 2. Add Your Files
+
+**Directory structure:**
+```
+Tool Name/
+  system_prompt.md          # The system prompt (required)
+  tools.json                # Tool/function schemas if available (optional)
+  model.md                  # Model info (optional)
+  README.md                 # Brief notes about source/version (optional)
+```
+
+**Naming conventions:**
+- Use the tool's official name for the directory
+- `system_prompt.md` for the main system prompt
+- `tools.json` for tool/function schemas
+- `model.md` for model configuration info
+
+### 3. Update the README Index
+
+Add your tool to the appropriate table in `README.md`:
+
+```markdown
+| Tool Name | ✅ | ✅ | Category | `Tool Name/` |
+```
+
+Categories: `Coding Agent` | `Browser AI` | `General AI` | `Autonomous Agent` | `App Builder` | `Productivity AI` | `Terminal AI` | `UI Generator` | `Search AI`
+
+### 4. Open a Pull Request
+
+**PR title format:** `Add [Tool Name] system prompt` or `Update [Tool Name] to v[version]`
+
+**PR description should include:**
+- Where the prompt came from (public disclosure, your own extraction, community research)
+- Version/date of the prompt if known
+- Any interesting patterns or notable aspects worth highlighting
+
+---
+
+## Quality Standards
+
+### For System Prompts
+- Must be the actual system prompt, not a paraphrase
+- Include the full prompt — partial prompts are less useful
+- Preserve exact formatting (whitespace, line breaks matter in prompts)
+- Mark clearly if it's a partial extraction
+
+### For Tool Schemas
+- Use valid JSON
+- Include all available fields (name, description, parameters)
+- If extracted programmatically, note the extraction method
+
+### For README Updates
+- Keep the table alphabetically sorted within each section
+- Use the exact category labels listed above
+- Link to the correct directory path
+
+---
+
+## Code of Conduct
+
+- Be respectful to other contributors
+- Don't claim credit for others' work
+- If you're submitting content originally found/extracted by someone else, credit them in the PR description
+- No spam PRs — quality over quantity
