+# LinearSolveAutotune.jl
+
+Automatic benchmarking and tuning for LinearSolve.jl algorithms.
+
+## Quick Start
+
+```julia
+using LinearSolve, LinearSolveAutotune
+
+# Run benchmarks with default settings (small, medium, and large sizes)
+results = autotune_setup()
+
+# View a summary of results
+display(results)
+
+# Plot all benchmark results
+plot(results)
+
+# Share your results with the community (optional)
+share_results(results)
+```
+
+## Features
+
+- **Automatic Algorithm Benchmarking**: Tests all available LU factorization methods
+- **Multi-size Testing**: Flexible size categories from small to very large matrices
+- **Element Type Support**: Tests with Float32, Float64, ComplexF32, ComplexF64
+- **GPU Support**: Automatically detects and benchmarks GPU algorithms if available
+- **Performance Visualization**: Generate plots on demand with `plot(results)`
+- **Community Sharing**: Optional telemetry to help improve algorithm selection
+
+## Size Categories
+
+The package now uses flexible size categories:
+
+- `:tiny` - Matrices from 5×5 to 20×20 (very small problems)
+- `:small` - Matrices from 20×20 to 100×100 (small problems)
+- `:medium` - Matrices from 100×100 to 300×300 (typical problems)
+- `:large` - Matrices from 300×300 to 1000×1000 (larger problems)
+- `:big` - Matrices from 10000×10000 to 100000×100000 (GPU/HPC)
+
+## Usage Examples
+
+### Basic Benchmarking
+
+```julia
+# Default: small, medium, and large sizes
+results = autotune_setup()
+
+# Test all size ranges
+results = autotune_setup(sizes = [:small, :medium, :large, :big])
+
+# Large matrices only (for GPU systems)
+results = autotune_setup(sizes = [:large, :big])
+
+# Custom configuration
+results = autotune_setup(
+    sizes = [:medium, :large],
+    samples = 10,
+    seconds = 1.0,
+    eltypes = (Float64, ComplexF64)
+)
+
+# View results and plot
+display(results)
+plot(results)
+```
+
+### Sharing Results
+
+After running benchmarks, you can optionally share your results with the LinearSolve.jl community to help improve automatic algorithm selection:
+
+```julia
+# Share your benchmark results
+share_results(results)
+```
+
+## Setting Up GitHub Authentication
+
+To share results, you need GitHub authentication. We recommend using the GitHub CLI:
+
+### Method 1: GitHub CLI (Recommended)
+
+1. **Install GitHub CLI**
+   - macOS: `brew install gh`
+   - Windows: `winget install --id GitHub.cli`
+   - Linux: See [cli.github.com](https://cli.github.com/manual/installation)
+
+2. **Authenticate**
+   ```bash
+   gh auth login
+   ```
+   Follow the prompts to authenticate with your GitHub account.
+
+3. **Verify authentication**
+   ```bash
+   gh auth status
+   ```
+
+### Method 2: GitHub Personal Access Token
+
+If you prefer using a token:
+
+1. Go to [GitHub Settings > Tokens](https://github.com/settings/tokens/new)
+2. Add description: "LinearSolve.jl Telemetry"
+3. Select scope: `public_repo`
+4. Click "Generate token" and copy it
+5. In Julia:
+   ```julia
+   ENV["GITHUB_TOKEN"] = "your_token_here"
+   share_results(results, sysinfo, plots)
+   ```
+
+## How It Works
+
+1. **Benchmarking**: The `autotune_setup()` function runs comprehensive benchmarks of all available LinearSolve.jl algorithms across different matrix sizes and element types.
+
+2. **Analysis**: Results are analyzed to find the best-performing algorithm for each size range and element type combination.
+
+3. **Preferences**: Optionally sets Julia preferences to automatically use the best algorithms for your system.
+
+4. **Sharing**: The `share_results()` function allows you to contribute your benchmark data to the community collection at [LinearSolve.jl Issue #669](https://github.com/SciML/LinearSolve.jl/issues/669).
+
+## Privacy and Telemetry
+
+- Sharing results is **completely optional**
+- Only benchmark performance data and system specifications are shared
+- No personal information is collected
+- All shared data is publicly visible on GitHub
+- You can review the exact data before sharing
+
+## API Reference
+
+### `autotune_setup`
+
+```julia
+autotune_setup(;
+    sizes = [:small, :medium, :large],
+    set_preferences = true,
+    samples = 5,
+    seconds = 0.5,
+    eltypes = (Float32, Float64, ComplexF32, ComplexF64),
+    skip_missing_algs = false
+)
+```
+
+**Parameters:**
+- `sizes`: Vector of size categories to test
+- `set_preferences`: Update LinearSolve preferences
+- `samples`: Number of benchmark samples per test
+- `seconds`: Maximum time per benchmark
+- `eltypes`: Element types to benchmark
+- `skip_missing_algs`: Continue if algorithms are missing
+
+**Returns:**
+- `results`: AutotuneResults object containing benchmark data and system info
+
+### `share_results`
+
+```julia
+share_results(results)
+```
+
+**Parameters:**
+- `results`: AutotuneResults object from `autotune_setup`
