+## Notes
+
+- The purpose of this submission is to keep prqlr 0.5.0, which has been archived from CRAN, existing on CRAN.
+- I don't fully understand why prqlr 0.5.0 was archived from CRAN,
+  because CRAN never contacted me or answered any of my questions.
+  So I don't know if this post fully fixes the prqlr 0.5.0 problem.
+- The Rust dependencies are not vendored because the size of the tarball vendoring the Rust dependencies
+  reached 12MB and does not meet the criteria for packages on CRAN.
+  Rust dependencies are downloaded from Crates.io during installation.
