-## 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

 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.
 
-Example `rollup.yml`:
+**Scrape Configuration Parameters:**
+
+- `requests_per_second`: *(float, optional)* The rate at which requests are made per second during web scraping. Default is `1.0`.
+- `burst_limit`: *(integer, optional)* The maximum number of requests that can be made in a burst. Default is `5`.
+
+These parameters help control the request rate to avoid overloading the target servers and to comply with their rate limits.
