  While the definition itself works unmodified, you can select the version of Alpine the container uses by updating the `VARIANT` arg in the included `devcontainer.json` (and rebuilding if you've already created the container).
 
 ```json
-"args": { "VARIANT": "3.13" }
+"args": { "VARIANT": "3.14" }
 ```
 
 You can also directly reference pre-built versions of `.devcontainer/base.Dockerfile` by using the `image` property in `.devcontainer/devcontainer.json` or updating the `FROM` statement in your own  `Dockerfile` to one of the following. An example `Dockerfile` is included in this repository.
 
 - `mcr.microsoft.com/vscode/devcontainers/base:alpine` (latest)
-- `mcr.microsoft.com/vscode/devcontainers/base:alpine-3.11`
 - `mcr.microsoft.com/vscode/devcontainers/base:alpine-3.12`
 - `mcr.microsoft.com/vscode/devcontainers/base:alpine-3.13`
 - `mcr.microsoft.com/vscode/devcontainers/base:alpine-3.14`
+- `mcr.microsoft.com/vscode/devcontainers/base:alpine-3.15`
 
 You can decide how often you want updates by referencing a [semantic version](https://semver.org/) of each image. For example:
 
 - `mcr.microsoft.com/vscode/devcontainers/base:0-alpine`
-- `mcr.microsoft.com/vscode/devcontainers/base:0.201-alpine`
-- `mcr.microsoft.com/vscode/devcontainers/base:0.201.5-alpine`
+- `mcr.microsoft.com/vscode/devcontainers/base:0.204-alpine`
+- `mcr.microsoft.com/vscode/devcontainers/base:0.204.0-alpine`
