+# Enforce consistent spacing before and after keywords (`keyword-spacing`)
+
+## Rule Details
+
+This rule extends the base [`eslint/keyword-spacing`](https://eslint.org/docs/rules/keyword-spacing) rule.
+This version adds support for generic type parameters on function calls.
+
+## How to use
+
+```cjson
+{
+  // note you must disable the base rule as it can report incorrect errors
+  "keyword-spacing": "off",
+  "@typescript-eslint/keyword-spacing": ["error"]
+}
+```
+
+## Options
+
+See [`eslint/keyword-spacing` options](https://eslint.org/docs/rules/keyword-spacing#options).
+
