+## Cryptic repository keys
+
+This folder contains RSA-encrypted symmetric AES keys.
+These are used by buildkite agents to decrypt the secrets embedded within this repository.
+Each buildkite agent contains an RSA secret key that is used to unlock the symmetric AES key that was used to encrypt the secrets within this repository.
+For more information, see the [`cryptic` buildkite plugin repository](https://github.com/staticfloat/cryptic-buildkite-plugin).

+## Experimental pipeline (`master` branch only)
+
+This is the [`julia-master->experimental`](https://buildkite.com/julialang/julia-master-experimental) pipeline.
+
+We use this pipeline for builders that are not yet stable enough to go into the main pipeline.
+
+These builders are triggered by GitHub webhook events, such as pushes and pull requests.
