+# Updating Alloy to a new Go version
+
+There is more to updating Go than simply updating the `go.mod` file.
+You will need to submit two pull requests:
+
+1. [Create a new build image.][build-image-instructions]
+2. Update Alloy to use the new Go version, and the new build image.
+   See [this][example-pr] pull request for an example.
+   At this point you can just search and replace all instances of the old version with the new one.
+   For example, "1.22.1" would be replaced with "1.22.5".
+
+The Go image which is used may sometimes have a name, like "bullseye". 
+The origins of the name are explained in more detail in [Go's DockerHub repository][go-dockerhub]:
+
+> Some of these tags may have names like bookworm or bullseye in them. 
+> These are the suite code names for releases of Debian⁠ and indicate which release the image is based on. 
+> If your image needs to install any additional packages beyond what comes with the image, 
+> you'll likely want to specify one of these explicitly to minimize breakage when there are new releases of Debian.

 The Grafana Alloy build images are used for CI workflows to manage builds of
 Grafana Alloy.
 
-There are the following images:
+There are several [images][alloy-build-image-dockerhub]:
 
 * `grafana/alloy-build-image:vX.Y.Z` (for building Linux containers)
-* `grafana/alloy-build-image:vX.Y.Z-boringcrypto` (for building Linux containers with boringcrypto)
+* `grafana/alloy-build-image:vX.Y.Z-boringcrypto` (currently unused, may be used for building Linux containers with boringcrypto)
 * `grafana/alloy-build-image:vX.Y.Z-windows` (for building Windows containers)
 
 (Where `X.Y.Z` is replaced with some semantic version, like 0.1.0).
 
-## Pushing new images
+[alloy-build-image-dockerhub]:https://hub.docker.com/repository/docker/grafana/alloy-build-image/general
 
-Once a commit is merged to main which updates the build-image Dockerfiles, a
-maintainer must push a tag matching the pattern `build-image/vX.Y.Z` to the
-grafana/alloy repo. For example, to create version v0.1.0 of the build images,
-a maintainer would push the tag `build-image/v0.1.0`.
+## Creating new images
+
+### Step 1: Update the main branch
+
+Open a PR to update the build images. 
+See [this][example-pr] pull request for an example.
+You need to change the following files:
+ * `tools/build-image/Dockerfile`
+ * `tools/build-image/windows/Dockerfile`
+ * `.drone/drone.yaml`
+ * `.drone/pipelines/build_images.jsonnet`
+ * `.github/workflows/check-linux-build-image.yml`
+
+[example-pr]:https://github.com/grafana/alloy/pull/1241/files
+
+### Step 2: Create a Git tag
+
+After the PR is merged to `main`, a maintainer must push a tag matching the pattern 
+`build-image/vX.Y.Z` to the `grafana/alloy` repo. 
+For example, to create version `0.1.1` of the build images,
+a maintainer would push the tag `build-image/v0.1.1`:
+
+```
+git checkout main
+git pull
+git tag -s build-image/v0.1.1
+git push origin build-image/v0.1.1
+```
 
 Automation will trigger off of this tag being pushed, building and pushing the
 new build images to Docker Hub.
