+# Weave Gitops Release Process
+
+The current release process for weave gitops is fairly straightforward. You need to:
+- Create the actual release
+- Update the `weave-gitops-docs` repository with documentation for the new version
+- Update the `CLI Installation` section of the `README.md` in the `weave-gitops` repository to reference the new version
+
+# Creating the release
+- Go to the `Releases` page for the weave-gitops repository
+- Click on `Draft a New Release`
+- Fill in the `Tag Version` field with the new version (format: `vN.N.N` or `vN.N.N-rc.N` for a pre-release). We have configured go-releaser to implicitly make a version ending in `-rc.N` a pre-release and one without the `rc-N` a full release (but that can be changed after the fact by editing the release if so desired).
+- Fill in the `Release Title` with the same version from the `Tag Version`
+- Click on `Publish Release`
+
+The go-releaser will spin for a bit, generating a changelog and artifacts.
+
+# Updating weave-gitops-docs
+Assuming any changes to user-visible behavior have already been documented for the new release (this should happen when the changes go into `weave-gitops`), you just need to create a new documentation version:
+- Create a branch from main
+- Checkout the new branch
+- Update `docs/installation.md`:
+  - Put the new version in the `curl` command
+  - Run `wego version` in a downloaded copy of the new release binary and update the `You should see:` section with the output
+- Create a new set of versioned documentation:
+  - Run:
+
+```console
+npm run docusaurus docs:version N.N.N
+```
+
+where the `N.N.N` matches the `N.N.N` from the weave gitops version.
+
+- Add and commit the new files (which will be a new directory containing copies of the files in main at the current point in time).
+- Create a PR and merge when approved
+
+# Updating the README
+- Once the release is available, change the version in the `curl` command shown in the `CLI Installation` section of the `README.md` in the weave-gitops repository
+- Create a PR and merge when approved
+
+That's it!
