 Description: Gaussian processes are flexible distributions to model functional data. Whilst
     theoretically appealing, they are computationally cumbersome except for small datasets.
-    This package implements two methods for scaling GP inference in Stan. First, a sparse
-    approximation of the likelihood that is generally applicable and, second, an exact method for
-    regularly spaced data modeled by stationary kernels using fast Fourier methods.
+    This package implements two methods for scaling Gaussian process inference in 'Stan'. First, a
+    sparse approximation of the likelihood that is generally applicable and, second, an exact method
+    for regularly spaced data modeled by stationary kernels using fast Fourier methods. Utility
+    functions are provided to compile and fit 'Stan' models using the 'cmdstanr' interface.

-## R CMD check results
+# Revisions in response to comments from 2023-12-18 for resubmission of 0.1.0.
+
+Thank you for the comments. Please find point-by-point responses below. Code changes are available at https://github.com/onnela-lab/gptoolsStan/pull/4.
+
+> Please always write package names, software names and API (application programming interface) names in single quotes in title and description. e.g: --> 'Stan' Please note that package names are case sensitive.
+
+We have wrapped 'Stan' and 'cmdstanr' in single quotes.
+
+> Please always explain all acronyms in the description text. -> 'GP'
+
+We have expanded acronyms.
+
+> If there are references describing the methods in your package, please add these in the description field of your DESCRIPTION file in the form
+> authors (year) <doi:...>
+> authors (year) <arXiv:...>
+> authors (year, ISBN:...)
+> or if those are not available: <https:...>
+> with no space after 'doi:', 'arXiv:', 'https:' and angle brackets for auto-linking. (If you want to add a title as well please put it in quotes: "Title")
+
+We have added a reference.
+
+> Please add `\value` to `.Rd` files regarding exported methods and explain the functions results in the documentation. Please write about the structure of the output (class) and also what the output means. (If a function does not return a value, please document that too, e.g. `\value{No return value, called for side effects}` or similar)
+> Missing Rd-tags:
+>
+>    - `gptools_include_path.Rd: \value`
+
+We have added a `\value` tag.
+
+> Please add small executable examples in your Rd-files to illustrate the use of the exported function but also enable automatic testing.
+
+We have added an example to the `.Rd` files. It is however wrapped in `\dontrun` because running the example requires that 'cmdstan' and 'cmdstanr' are installed.
+
