+# Configuring Clippy
+
+> **Note:** The configuration file is unstable and may be deprecated in the future.
+
+Some lints can be configured in a TOML file named `clippy.toml` or `.clippy.toml`. It contains a
+basic `variable = value` mapping eg.
+
+```toml
+avoid-breaking-exported-api = false
+blacklisted-names = ["toto", "tata", "titi"]
+cognitive-complexity-threshold = 30
+```
+
+See the [list of lints](https://rust-lang.github.io/rust-clippy/master/index.html) for more information about which
+lints can be configured and the meaning of the variables.
+
+To deactivate the "for further information visit *lint-link*" message you can define the `CLIPPY_DISABLE_DOCS_LINKS`
+environment variable.
+
+### Allowing/denying lints
+
+You can add options to your code to `allow`/`warn`/`deny` Clippy lints:
+
+* the whole set of `Warn` lints using the `clippy` lint group (`#![deny(clippy::all)]`)
+
+* all lints using both the `clippy` and `clippy::pedantic` lint groups (`#![deny(clippy::all)]`,
+  `#![deny(clippy::pedantic)]`). Note that `clippy::pedantic` contains some very aggressive lints prone to false
+  positives.
+
+* only some lints (`#![deny(clippy::single_match, clippy::box_vec)]`, etc.)
+
+* `allow`/`warn`/`deny` can be limited to a single function or module using `#[allow(...)]`, etc.
+
+Note: `allow` means to suppress the lint for your code. With `warn` the lint will only emit a warning, while with `deny`
+the lint will emit an error, when triggering for your code. An error causes clippy to exit with an error code, so is
+useful in scripts like CI/CD.
+
+If you do not want to include your lint levels in your code, you can globally enable/disable lints by passing extra
+flags to Clippy during the run:
+
+To allow `lint_name`, run
+
+```terminal
+cargo clippy -- -A clippy::lint_name
+```
+
+And to warn on `lint_name`, run
+
+```terminal
+cargo clippy -- -W clippy::lint_name
+```
+
+This also works with lint groups. For example you can run Clippy with warnings for all lints enabled:
+
+```terminal
+cargo clippy -- -W clippy::pedantic
+```
+
+If you care only about a single lint, you can allow all others and then explicitly warn on the lint(s) you are
+interested in:
+
+```terminal
+cargo clippy -- -A clippy::all -W clippy::useless_format -W clippy::...
+```
+
+### Specifying the minimum supported Rust version
+
+Projects that intend to support old versions of Rust can disable lints pertaining to newer features by specifying the
+minimum supported Rust version (MSRV) in the clippy configuration file.
+
+```toml
+msrv = "1.30.0"
+```
+
+The MSRV can also be specified as an inner attribute, like below.
+
+```rust
+#![feature(custom_inner_attributes)]
+#![clippy::msrv = "1.30.0"]
+
+fn main() {
+    ...
+}
+```
+
+You can also omit the patch version when specifying the MSRV, so `msrv = 1.30`
+is equivalent to `msrv = 1.30.0`.
+
+Note: `custom_inner_attributes` is an unstable feature so it has to be enabled explicitly.
+
+Lints that recognize this configuration option can be
+found [here](https://rust-lang.github.io/rust-clippy/master/index.html#msrv)
