+#' Generate Multiple Random Normal Walks
+#'
+#' @family Generator Functions
+#'
+#' @author Steven P. Sanderson II, MPH
+#'
+#' @details
+#' This function generates multiple random walks, which are sequences of steps
+#' where each step is a random draw from a normal distribution. The user can
+#' specify the number of walks, the number of steps in each walk, and the
+#' parameters of the normal distribution (mean and standard deviation). The
+#' function also allows for sampling a proportion of the steps and optionally
+#' sampling with replacement.
+#'
+#' The output tibble includes several computed columns for each walk, such as the
+#' cumulative sum, product, minimum, and maximum of the steps.
+#'
+#' @description
+#' The `random_normal_walk` function is useful for simulating random processes
+#' and can be applied in various fields such as finance, physics, and biology
+#' to model different stochastic behaviors.
+#'
+#' @param .num_walks An integer specifying the number of random walks to generate. Default is 25.
+#' @param .n An integer specifying the number of steps in each walk. Default is 100.
+#' @param .mu A numeric value indicating the mean of the normal distribution. Default is 0.
+#' @param .sd A numeric value indicating the standard deviation of the normal distribution. Default is 0.1.
+#' @param .initial_value A numeric value indicating the initial value of the walks. Default is 0.
+#' @param .samp A logical value indicating whether to sample the normal distribution values. Default is TRUE.
+#' @param .replace A logical value indicating whether sampling is with replacement. Default is TRUE.
+#' @param .sample_size A numeric value between 0 and 1 specifying the proportion of `.n` to sample. Default is 0.8.
+#'
+#' @return A tibble containing the generated random walks with the following columns:
+#' \itemize{
+#'   \item `walk_number`: Factor representing the walk number.
+#'   \item `x`: Step index.
+#'   \item `y`: Normal distribution values.
+#'   \item `cum_sum`: Cumulative sum of `y`.
+#'   \item `cum_prod`: Cumulative product of `y`.
+#'   \item `cum_min`: Cumulative minimum of `y`.
+#'   \item `cum_max`: Cumulative maximum of `y`.
+#' }
+#' The tibble includes attributes for the function parameters.
+#'
+#' @examples
+#' # Generate 10 random walks with 50 steps each
