+### What it does
+Checks for nested `if` statements which can be collapsed
+by `&&`-combining their conditions.
+
+### Why is this bad?
+Each `if`-statement adds one level of nesting, which
+makes code look more complex than it really is.
+
+### Example
+```
+if x {
+    if y {
+        // …
+    }
+}
+```
+
+Use instead:
+```
+if x && y {
+    // …
+}
+```
