+
+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
+```
