 1. Checks that the number of inputs matches what the basis being evaluated expects (e.g., one input for a 1-D basis, N inputs for an N-D basis, or the sum of N 1-D bases), and raises a `ValueError` if this is not the case.
 2. Calls `_get_samples` method, which returns equidistant samples over the domain of the basis function. The domain may depend on the type of basis.
-3. Calls the `_evaluate` method.
+3. Calls the [`_evaluate`](nemos.basis._basis.Basis._evaluate) method on these samples.
 4. Returns both the sample grid points of shape `(m1, ..., mN)`, and the evaluation output at each grid point of shape `(m1, ..., mN, n_basis_funcs)`, where `mi` is the number of sample points for the i-th axis of the grid.
