Hey Dillon! 👋

Thanks for creating this! I'm new to the OCaml ecosystem and currently researching the web side while writing a backend in OCaml and Dream.

I came to https://github.com/melange-re/melange-opam-template and some time later found your tweet about this project.

Do you think it's worth linking to that project at the end of your project's README, to spread the knowledge about the ecosystem? That template is focused on React but I think it's also useful for backend stuff if you remove React (I think, I haven't used it, just took a quick gander).

Also thanks for creating amazing free content and videos on Effect_TS, OCaml, and all that good FP stuff! 💪
