     """
     Class used to estimate approximate Bayesian posterior distributions or
     perform Bayesian optimization using a Gaussian process surrogate model
+
+    Initial parameters:
+
+    Parameters
+    ----------
+    theta : array-like
+        Input features (n_samples x n_features).  Defaults to None.
+    y : array-like
+        Input result of forward model (n_samples,). Defaults to None.
+    lnprior : function
+        Defines the log prior over the input features.
+    lnlike : function
+        Defines the log likelihood function.  In this function, it is assumed
+        that the forward model is evaluated on the input theta and the output
+        is used to evaluate the log likelihood.
+    priorSample : function
+        Method to randomly sample points over region allowed by prior
+    bounds : tuple/iterable
+        Hard bounds for parameters
+    gp : george.GP, optional
+        Gaussian Process that learns the likelihood conditioned on forward
+        model input-output pairs (theta, y). It's recommended that users
+        specify their own kernel, GP using george. If None is provided, then
+        approxposterior initialized a GP with a single ExpSquaredKernel as
+        these work well in practice.
+    algorithm : str, optional
+        Point selection algorithm that specifies which utility (also
+        referred to as acquisition) function to use.  Defaults to bape.
+        Options are bape (Bayesian Active Learning for Posterior Estimation,
+        Kandasamy et al. (2015)), agp (Adapted Gaussian Process Approximation,
+        Wang & Li (2017)), alternate (between AGP and BAPE), and jones
+        (Jones et al. (1998) expected improvement).
+        Case doesn't matter. If alternate, runs agp on even numbers and bape
+        on odd.
+
+        For approximate Bayesian posterior estimation, bape or alternate
+        are typically the best optimizations. For Bayesian optimization,
+        jones (expected improvement) usually performs best.
