+Docker image with everything you might need for developing apps in Go.
+
+**Note that for newer mac hardware you have to use Docker Desktop or amd64 virtual machine in lima/other tools!**
+
+## What's inside
+
+Debian 12 (slim) is used as base image.

+## HOME
+
+Home directory is `/home/container`.
+
+## Caching
+
+Go's build cache resides in `/home/container/.cache`, `GOCACHE` environment variable is defined. You can mount it when needed in Dockerfile as:
+
+```Dockerfile
+RUN --mount=type=cache,target="$GOCACHE" go build
+```
+
+## Utilities examples
+
+### JUnit report generation (for Gitlab)
+
+```shell
+go test -v 2>&1 ./... | go-junit-report -set-exit-code > unit-report.xml
+```
