+## Releasing
+
+To be able to create a release you need to be on the [maintainers](https://github.com/orgs/aiken-lang/teams/maintainers) team.
+This means that only core team members can create releases. We have a
+[github action](https://github.com/aiken-lang/aiken/blob/main/.github/workflows/release.yml) for creating the binaries and a github release.
+The process follows these steps:
+
+1. `cargo release --execute`
+2. After a release is created by the github action fill in the release notes. Try to tag contributors so that they show up in the release.
+3. Screenshot the result of `aikup` and post on twitter saying "We've just released vx.x.x". [example](https://twitter.com/aiken_eng/status/1693084816931987930?s=20)
+
+> `cargo release` takes arguments and flags to tell it how to bump the version number. Examples include `cargo release 1.0.16-alpha` and `cargo release major`.
+>
+> The root `Cargo.toml` in the repo contains this configuration for `cargo release`:
+>
+> ```toml
+> [workspace.metadata.release]
+> shared-version = true
+> tag-name = "v{{version}}"
+> ```
