+### What it does
+Checks for usage of `!` or `!=` in an if condition with an
+else branch.
+
+### Why is this bad?
+Negations reduce the readability of statements.
+
+### Example
+```
+if !v.is_empty() {
+    a()
+} else {
+    b()
+}
+```
+
+Could be written:
+
+```
+if v.is_empty() {
+    b()
+} else {
+    a()
+}
+```
