 When performing end-state correction simulations using the `emle-sire` interface
 there is no need to specify the `lambda_interpolate` keyword when creating an
 `EMLECalculator` instance. Instead, interpolation can be enabled when creating a
-`Sire` dynamics object via the same keyword. (See the [tutorial](https://github.com/OpenBioSim/sire/blob/feature_emle/doc/source/tutorial/part08/01_eml.rst) for details.)
