-     * @brief Construct a new Series

-     * @param filepath The backend will be determined by the filepath extension.
+     * @brief Construct a new Series.


Let's add a .. tip:: in the First Read overview:
https://openpmd-api.readthedocs.io/en/latest/usage/firstread.html#open

That explains %T and %E in 1-2 sentences.

.. tip:: Use the wildcards `%T` to match filename encoded iterations and `%E` to match supported extensions such as `.h5` and `.bp`.

ax3l

This is awesome. Please add the .. tip:: and then we ready.

todo: 1. temporarily initialize with dummy io handler 2. move the late initialization logic to IOHandler()
