+define the `CLIPPY_DISABLE_WIKI_LINKS` environment variable.
+
+### Allowing/denying lints
+
+You can add options to `allow`/`warn`/`deny`:
+
+* the whole set of `Warn` lints using the `clippy` lint group (`#![deny(clippy)]`)
+
+* all lints using both the `clippy` and `clippy_pedantic` lint groups (`#![deny(clippy)]`,
+ `#![deny(clippy_pedantic)]`). Note that `clippy_pedantic` contains some very aggressive
+ lints prone to false positives.
+
+* only some lints (`#![deny(single_match, box_vec)]`, etc)
+
+* `allow`/`warn`/`deny` can be limited to a single function or module using `#[allow(...)]`, etc
+
+Note: `deny` produces errors instead of warnings.
