+## Build and Run Commands
+
+```bash
+# Build the binary
+go build -o rollup .
+
+# Run directly
+go run main.go [command]
+
+# Run tests
+go test ./...
+
+# Run a single test
+go test -run TestName ./path/to/package
+```
+
+## Project Overview
+
+Rollup is a Go CLI tool that aggregates text-based files and webpages into markdown files. It has three main commands:
+- `files` - Rolls up local files into a single markdown file
+- `web` - Scrapes webpages and converts to markdown using Playwright
+- `generate` - Creates a default rollup.yml config file
+
+## Architecture
+
+**Entry Point**: `main.go` initializes Playwright browser and loads config before executing commands via Cobra.
+
+**Command Layer** (`cmd/`):
+- `root.go` - Cobra root command with global flags (--config, --verbose)
+- `files.go` - File aggregation with glob pattern matching for ignore/codegen detection
+- `web.go` - Web scraping orchestration, converts config site definitions to scraper configs
+- `generate.go` - Scans directory for text file types and generates rollup.yml
+
+**Internal Packages**:
+- `internal/config` - YAML config loading and validation. Defines `Config`, `SiteConfig`, `PathOverride` structs
+- `internal/scraper` - Playwright-based web scraping with rate limiting, HTML-to-markdown conversion via goquery and html-to-markdown library
+
+**Key Dependencies**:
+- `spf13/cobra` - CLI framework
+- `playwright-go` - Browser automation for web scraping
+- `PuerkitoBio/goquery` - HTML parsing and CSS selector extraction
+- `JohannesKaufmann/html-to-markdown` - HTML to markdown conversion
+
+## Configuration
+
+The tool reads from `rollup.yml` by default. Key config fields:
+- `file_extensions` - File types to include in rollup
+- `ignore_paths` / `code_generated_paths` - Glob patterns for exclusion
+- `sites` - Web scraping targets with CSS selectors, path filtering, rate limiting

 ## Configuration
 
-Rollup can be configured using a YAML file. By default, it looks for `rollup.yml` in the current directory. You can specify a different configuration file using the `--config` flag.
+Rollup reads from `rollup.yml` by default. Use `--config` to specify a different file.
 
-Example `rollup.yml`:

 ## Examples
 
-1. Rollup files with default configuration:
+### File Aggregation
 
-   ```bash
+```bash
-   rollup files
+# Rollup files using config file
-   ```
+rollup files
 
-2. Web scraping with multiple URLs:
+# Specify file types and ignore patterns
+rollup files --types=go,js,ts --ignore="vendor/**,*_test.go"
 
-   ```bash
+# Rollup a specific directory
-   rollup web --urls=https://example.com,https://another-example.com
+rollup files --path=/path/to/project
-   ```
+```
 
-3. Generate a default configuration file:
+### Web Scraping
 
-   ```bash
+```bash
-   rollup generate
+# Scrape URLs from command line
-   ```
+rollup web --urls=https://example.com/docs
 
-4. Use a custom configuration file:
+# Scrape multiple URLs
+rollup web --urls=https://example.com,https://another.com
 
-   ```bash
+# Extract specific content with CSS selector
-   rollup files --config=my-config.yml
+rollup web --urls=https://example.com --css=".article-content"
-   ```
 
-5. Web scraping with separate output files:
+# Exclude elements from scraped content
+rollup web --urls=https://example.com --css=".content" --exclude=".ads,.sidebar"
 
-   ```bash
+# Output to separate files
-   rollup web --urls=https://example.com,https://another-example.com --output=separate
+rollup web --urls=https://example.com --output=separate
-   ```
+```
 
-6. Rollup files with specific types and ignore patterns:
+### Configuration Generation
 
-   ```bash
+```bash
-   rollup files --types=go,md --ignore=vendor/**,*_test.go
+# Generate rollup.yml based on files in current directory
-   ```
+rollup generate
+```
 
-7. Web scraping with depth and CSS selector:
+### Using Custom Config
-   ```bash
+
-   rollup web --urls=https://example.com --depth=2 --css=.main-content
+```bash
-   ```
+rollup files --config=my-config.yml
+rollup web --config=my-config.yml
+```
+
+## Output
+
+### File Rollup Output
+
+The `files` command generates a markdown file named `<project-name>-<timestamp>.rollup.md` containing all matched files:
+
+```markdown
+# File: src/main.go
+
+​```go
+package main
+// ... file contents
+​```
+
+# File: docs/README.md (Code-generated, Read-only)
+
+​```md
+// ... file contents
+​```
+```
+
+### Web Rollup Output
+
+The `web` command generates markdown files from scraped content, with filenames based on the page title or URL.
