# Task ID: 38

**Title:** Create User Documentation

**Status:** done

**Dependencies:** 11, 12, 14, 16, 18, 22, 23, 25

**Priority:** low

**Description:** Write comprehensive user documentation including installation, configuration, and command reference.

**Details:**

Create documentation in `docs/`:

`README.md` (project root):
- Quick start guide
- Installation instructions
- Basic usage examples

`docs/installation.md`:
- Prerequisites (Python 3.10+, Azure AD app registration)
- pip install instructions
- Configuration setup

`docs/configuration.md`:
- config.toml structure
- Tenant profile setup
- Environment variables

`docs/commands.md`:
- Full CLI reference generated from Typer
- Examples for each command
- Common workflows

`docs/troubleshooting.md`:
- Common errors and solutions
- Debug logging
- API permission issues

**Test Strategy:**

Review documentation for completeness, verify all commands are documented, test installation instructions on clean system.

## Implementation Notes

### Session: 2026-01-31 10:05 - Agent: claude-opus-4-5-20251101

**Status:** Implemented

#### What Was Done
- Created `docs/` directory structure
- Created `docs/installation.md` - Prerequisites, pip install, certificate setup, tenant configuration
- Created `docs/configuration.md` - config.toml structure, tenant profiles, environment variables, auth methods
- Created `docs/commands.md` - Full CLI reference with all 6 command groups, options, and examples
- Created `docs/troubleshooting.md` - Exit codes (0-8), error handling, debug logging, common workflows
- Created `README.md` - Quick start guide, feature overview, example usage, links to docs/

#### Key Decisions Made
- **Documentation structure**: Followed task spec exactly with separate files for installation, configuration, commands, and troubleshooting
- **Command reference**: Generated from actual CLI `--help` output to ensure accuracy vs spec docs
- **Exit codes**: Documented all 8 exit codes (0-8) including CONTRACT_ERROR even though PRD says not user-facing
- **README vs CLAUDE.md**: Created README.md for users, CLAUDE.md remains for AI agents as recommended

#### Files Created
- `docs/installation.md` (4,680 bytes) - Installation prerequisites and setup
- `docs/configuration.md` (6,532 bytes) - Config file and tenant management
- `docs/commands.md` (16,623 bytes) - Complete CLI command reference
- `docs/troubleshooting.md` (9,346 bytes) - Error handling and debugging
- `README.md` (5,711 bytes) - Project overview and quick start

#### Patterns Discovered
- CLI has `api-check` command (not in original spec) - documented for contract validation
- `--no-cache` option mentioned in specs but not implemented in actual CLI (global options differ slightly)
- Policy type aliases work both ways: `calling` → `TeamsCallingPolicy` and vice versa

#### Open Items for Next Agent
- None - task fully complete

#### Gotchas and Warnings
- License file referenced in README but doesn't exist yet (may need to create LICENSE file)
- GitHub repo URL in README is placeholder (`your-org/teams-phone-cli`)
