+# if not set a comma-separated list will be printed to stdout
 DOCKER_AUTOTAG_OUTPUT_FILE=
+# adds a given suffix to every determined tag
 DOCKER_AUTOTAG_SUFFIX=
+# version string to use; returns 'latest' if nothing is specified
 DOCKER_AUTOTAG_VERSION=
+# comma-seprated list of static tags to add to the result set
 DOCKER_AUTOTAG_EXTRA_TAGS=
+# 'latest' tag would only be used if determined tag list is empty; adds always 'latest' to the result

+## 'v' prefixes e.g. from git tags will be removed
+DOCKER_AUTOTAG_VERSION=v1.0.1 docker-autotag
+# 1.0.1,1.0,1
+
+## unsufficient semver version strings will be tried to convert automatically
+## if conversion doesn't work return 'latest'
+DOCKER_AUTOTAG_VERSION=1.0 docker-autotag
+# 1.0.0,1.0,1
