+
+HTML parsing and querying with CSS selectors.
+
+`scraper` is on [Crates.io][crate] and [GitHub][github].
+
+[crate]: https://crates.io/crates/scraper
+[github]: https://github.com/causal-agent/scraper
+[tests]: https://github.com/causal-agent/scraper/actions/workflows/test.yml
+
+Scraper provides an interface to Servo's `html5ever` and `selectors` crates, for browser-grade parsing and querying.
+
+## Examples
+
+### Parsing a document
+
+```rust
+use scraper::Html;
+
+let html = r#"
+    <!DOCTYPE html>
+    <meta charset="utf-8">
+    <title>Hello, world!</title>
+    <h1 class="foo">Hello, <i>world!</i></h1>
+"#;
+
+let document = Html::parse_document(html);
+```
+
+### Parsing a fragment
+
+```rust
+use scraper::Html;
+let fragment = Html::parse_fragment("<h1>Hello, <i>world!</i></h1>");
+```
+
+### Parsing a selector
+
+```rust
+use scraper::Selector;
+let selector = Selector::parse("h1.foo").unwrap();
+```
+
+### Selecting elements
+
+```rust
+use scraper::{Html, Selector};
+
+let html = r#"
+    <ul>
+        <li>Foo</li>
+        <li>Bar</li>
+        <li>Baz</li>
+    </ul>
+"#;
+
+let fragment = Html::parse_fragment(html);
+let selector = Selector::parse("li").unwrap();
+
+for element in fragment.select(&selector) {
+    assert_eq!("li", element.value().name());
+}
+```
+
+### Selecting descendent elements
+
+```rust
+use scraper::{Html, Selector};
+
+let html = r#"
+    <ul>
+        <li>Foo</li>
+        <li>Bar</li>
+        <li>Baz</li>
+    </ul>
+"#;
+
+let fragment = Html::parse_fragment(html);
+let ul_selector = Selector::parse("ul").unwrap();
+let li_selector = Selector::parse("li").unwrap();
+
+let ul = fragment.select(&ul_selector).next().unwrap();
+for element in ul.select(&li_selector) {
+    assert_eq!("li", element.value().name());
+}
+```
+
+### Accessing element attributes
+
+```rust
+use scraper::{Html, Selector};
+
+let fragment = Html::parse_fragment(r#"<input name="foo" value="bar">"#);
+let selector = Selector::parse(r#"input[name="foo"]"#).unwrap();
+
+let input = fragment.select(&selector).next().unwrap();
+assert_eq!(Some("bar"), input.value().attr("value"));
+```
+
+### Serializing HTML and inner HTML
+
+```rust
+use scraper::{Html, Selector};
+
+let fragment = Html::parse_fragment("<h1>Hello, <i>world!</i></h1>");
+let selector = Selector::parse("h1").unwrap();
+
+let h1 = fragment.select(&selector).next().unwrap();
+
+assert_eq!("<h1>Hello, <i>world!</i></h1>", h1.html());
+assert_eq!("Hello, <i>world!</i>", h1.inner_html());
+```
+
+### Accessing descendent text
+
+```rust
+use scraper::{Html, Selector};
+
+let fragment = Html::parse_fragment("<h1>Hello, <i>world!</i></h1>");
+let selector = Selector::parse("h1").unwrap();
+
+let h1 = fragment.select(&selector).next().unwrap();
+let text = h1.text().collect::<Vec<_>>();
+
+assert_eq!(vec!["Hello, ", "world!"], text);
+```
+
+### Manipulating the DOM
+
+```rust
+use html5ever::tree_builder::TreeSink;
+use scraper::{Html, Selector};
+
+let html = "<html><body>hello<p class=\"hello\">REMOVE ME</p></body></html>";
+let selector = Selector::parse(".hello").unwrap();
+let mut document = Html::parse_document(html);
+let node_ids: Vec<_> = document.select(&selector).map(|x| x.id()).collect();
+for id in node_ids {
+    document.remove_from_parent(&id);
+}
+assert_eq!(document.html(), "<html><head></head><body>hello</body></html>");
+```
