-> If you configured the `filenames/match-regex` rule, please note we have adapted the match regex rule into `eslint-plugin-github` as the original `eslint-filenames-plugin` is no longer maintained and needed an ESLint v9/flat config update. Please update the name to `github/filenames-match-regex` and keep the same configuration. Note, that the default rule is camelCase with one hump. If there are multiple humps like `camelCaseTest.js`, this default rule will error out. Here's an example for this rule with custom configuration:

-regex - Regex to match the filename structure. Defaults to camelCase.
+regex - Regex to match the filename structure. Defaults to kebab case or camelCase with one hump.
 
+Default:
+
+```json
+{
+  "filenames-match-regex": [

+}
+```

+If you want to add custom regex such as matching all camelCase, add the regex as a string. For example, for camelCase it would look like:
 
 ```json
 {
   "filenames-match-regex": [
     "error",
-    "^[a-z0-9-]+(.[a-z0-9-]+)?$"
+    "^([a-z0-9]+)([A-Z][a-z0-9]+)*$"
