+## Building Vanilla Image
+
+To build `macos-sonoma-vanilla`:
+
+```bash
+packer build templates/vanilla-sonoma.pkr.hcl
+```
+
+Optionally, SIP can be disabled for each image by running the following commands:
+
+```bash
+packer build -var vm_name=sonoma-vanilla templates/disable-sip.pkr.hcl
+```
+
+## Building Base Image
+
+```bash
+packer build -var vm_name=sonoma-vanilla templates/base.pkr.hcl

+
+## Building Xcode Image
+
+```bash
+packer build -var macos_version=sonoma -var xcode_version="[15.4]" templates/xcode.pkr.hcl

+## macOS Packer Templates for Tart
 
-Repository with Packer templates to build [Tart VMs](https://github.com/cirruslabs/tart) to use with [Cirrus CI](https://cirrus-ci.org/guide/macOS/).
+Repository with Packer templates to build macOS [Tart](https://tart.run/) virtual machines to use with self-hosted
+GitHub Actions runners, [Cirrus Runners](https://cirrus-runners.app/) or [any other automation](https://tart.run/integrations/cirrus-cli/).
 
-* `macos-{monterey,ventura}-vanilla` image has nothing pre-installed
-* `macos-{monterey,ventura}-base` image has only `brew` pre-installed
-* `macos-{monterey,ventura}-xcode:N` image is based on `macos-{monterey,ventura}-base` image and has `Xcode N` with [`Flutter`](https://flutter.dev/) pre-installed
+The following image variants are currently available:
 
-See a full list of VMs available on Cirrus CI [here](https://github.com/orgs/cirruslabs/packages?tab=packages&q=macos-).
+* `macos-{golden-gate,tahoe,sequoia,sonoma}-vanilla` — a vanilla macOS installation with helpful tweaks such as auto-login, but no additional software preinstalled
+* `macos-{tahoe,sequoia,sonoma}-base` — based on `macos-{tahoe,sequoia,sonoma}-vanilla` image, it comes with `brew` and [other useful software](https://github.com/cirruslabs/macos-image-templates/blob/main/templates/base.pkr.hcl) pre-installed, but without Xcode
+* `macos-{tahoe,sequoia,sonoma}-xcode:N` — based on `macos-{tahoe,sequoia,sonoma}-base` image and has `Xcode N` with [`Flutter`](https://flutter.dev/) pre-installed
+* `macos-runner:{tahoe,sequoia,sonoma}` — a variant of `xcode:N` with several versions of `Xcode` pre-installed and [`xcodes` tool](https://github.com/XcodesOrg/xcodes) to switch between them.
 
-## Building Vanilla Image
+See a full list of VMs available [here](https://github.com/orgs/cirruslabs/packages?tab=packages&q=macos-).
 
-To build `macos-monterey-vanilla`:
+## Release Cadence
 
-```bash
-packer build templates/vanilla-monterey.pkr.hcl
-```
+Once a new version of Xcode is released, we will initiate a GitHub release which will automatically build and push
+a new version of the `macos-{tahoe,sequoia}-xcode:N`. This generally happens the next weekend after a release.
+Please watch this repository releases to get notified about new images.
 
-To build `macos-ventura-vanilla`:
+## Update Cadence
 
-```bash
-packer build templates/vanilla-ventura.pkr.hcl
-```
+Some of the images are regularly getting rebuild in order to update the pre-installed packages. 
 
-Optionally, SIP can be disabled for each image by running the following commands:
-
-```bash
-packer build -var vm_name=monterey-vanilla templates/disable-sip.pkr.hcl
-```
-
-```bash
-packer build -var vm_name=ventura-vanilla templates/disable-sip.pkr.hcl
-```
-
-## Building Base Image
-
-```bash
-packer build -var-file="variables.pkrvars.hcl" templates/base.pkr.hcl
-```
-
-## Building Xcode Image
-
-```bash
-packer build -var-file="variables.pkrvars.hcl" templates/xcode.pkr.hcl
-```
+[This workflow](.github/workflows/monthly.yml) defines images that are getting rebuilt monthly on the first Saturday of the month.
