+### Disabling safety checks
+
+For purposes like quick prototyping, you can disable the safety checks by appending the `--skip-lint` option to Anchor CLI commands:
+
+```bash
+anchor build --skip-lint
+# or
+anchor test --skip-lint
+```
+
+Or, you can disable the safety checks globally by setting `skip-lint` to `true` in the `[features]` section of your `Anchor.toml` file.
+
+```toml
+[features]
+skip-lint = true
+```
