+# Jenkins Pipeline Shared Library Sample
+
+This project provides easy example of shared library which can be used into Jenkins pipeline.
+
+Setup instructions
+
+1. In Jenkins, go to Manage Jenkins → Configure System. Under Global Pipeline Libraries, add a library with the following settings:
+  * Library name: jenkins-pipeline-shared-lib-sample
+  * Default version: Specify a Git reference (branch or commit SHA), e.g. master
+  * Retrieval method: Modern SCM
+  * Select the Git type
+  * Project repository: https://gitlab.mynisum.com/mtehami/jenkins-shared-library-example.git
+  * Credentials: (leave blank)
+  * You may have to turn off ssl verification using:     git.exe config --global http.sslVerify false
+
+2. Then create a Jenkins job with the following pipeline (note that the underscore _ is not a typo):
+
+```
+@Library('jenkins-pipeline-shared-lib-sample')_
+
+stage('Print Build Info') {
+    printBuildinfo {
+        name = "Sample Name"
+    }
+} stage('Disable balancer') {
+    disableBalancerUtils()
+} stage('Deploy') {
+    deploy()
+} stage('Enable balancer') {
+    enableBalancerUtils()
+} stage('Check Status') {
+    checkStatus()
+}
+```
+
+Run job!
