+# External Jenkins pipeline helpers
+
+## Usage:
+Inside Jenkins pipeline script run two following commands:
+```groovy
+// This shell command will download groovy helpers file
+sh "curl -L http://[git-url]/[organization]/[repo-name]/raw/branch/master/helpers.groovy -o helpers.groovy"
+
+// This will load script to the pipeline
+load "helpers.groovy"
+```
+> This can be used in scripting pipeline syntax only!
+
+After all you will have in your pipeline all functions that `helpers.groovy` provides:
+- stageWithChecks
+- setSuccessCheck
+- withGiteaCreds
