+# Github config and workflows
+
+In this folder there is configuration for codecoverage, dependabot, and ci
+workflows that check the library more deeply than the default configurations.
+
+This folder can be or was merged using a --allow-unrelated-histories merge
+strategy from <https://github.com/jonhoo/rust-ci-conf/> which provides a
+reasonably sensible base for writing your own ci on. By using this strategy
+the history of the CI repo is included in your repo, and future updates to
+the CI can be merged later.
+
+To perform this merge run:
+
+```shell
+git remote add ci https://github.com/jonhoo/rust-ci-conf.git
+git fetch ci
+git merge --allow-unrelated-histories ci/main
+```
+
+An overview of the files in this project is available at:
+<https://www.youtube.com/watch?v=xUH-4y92jPg&t=491s>, which contains some
+rationale for decisions and runs through an example of solving minimal version
+and OpenSSL issues.
