+#### `rules:exists`

+`exists` accepts an array of paths and will match if any of these paths exist
+as files in the repository.
+
+For example:
+
+```yaml
+job:
+  script: docker build -t my-image:$CI_COMMIT_REF_SLUG .
+  rules:
+    - exists:
+      - Dockerfile

+You can also use glob patterns to match multiple files in any directory within

+For example:
+
+```yaml
+job:
+  script: bundle exec rspec
+  rules:
+    - exists:
+      - spec/**.rb

+
+NOTE: **Note:**
+For performance reasons, using `exists` with patterns is limited to 10000
+checks. After the 10000th check, rules with patterned globs will always match.
