+👉 Use `matches` pipe to check the value of some variable. This pipe returns the given string if it matches the reference string, and returns an empty string otherwise. This is useful for running conditional commands based on some variable:
+
+```yml

+  # ...
+
+  - if:
+      eval: '{{ some_var | matches: some value }}'

+You can also pass regular expressions to `matches` pipe to check if given string matches given pattern:

+```yml
+if:
+  eval: '{{ database | matches: /Mongo/ }}'
