+Jenkins
+=======
+
+Jenkins, an open-source automation server, is a powerful tool for continuous
+integration and delivery. While countless resources exist on this topic, we
+will explore unique insights and uncover hidden gems to make your installation
+journey smooth and hassle-free.
+
+Prerequisites
+-------------
+
+To install Jenkins on your machine, ensure that you have the following prerequisites:
+
+* Homebrew installed
+
+* Java Development Kit (JDK) installed
+
+* Administrative access to your machine
+
+Steps to Install Jenkins on Your Machine
+----------------------------------------
+
+* Install Jenkins using Homebrew by running the following command:
+
+```shell
+brew install jenkins-lts
+```
+
+The "lts" flag ensures that the long-term support version of Jenkins is installed.
+
+* If you want to access your Jenkins server from anywhere,
+
+  not just your local machine, you need to modify the Jenkins configuration file.
+
+  Open the file using the following command:
+
+```shell
+sudo vi /usr/local/opt/jenkins-lts/homebrew.mxcl.jenkins-lts.plist
+```
+
+* In the file, locate the line:
+
+```shell
+<string>--httpListenAddress=127.0.0.1</string>
+```
+
+Replace it with:
+
+```shell
+<string>--httpListenAddress=0.0.0.0</string>
+```
+
+This change allows Jenkins to listen on all available network interfaces.
+
+* Start the Jenkins server using the following command:
+
+```shell
+brew services start jenkins-lts
+```
+
+Jenkins will now start running as a background service on your machine.
+
+* By default, Jenkins uses port 8080. If you want to change the port, open
+
+  the Jenkins configuration file again:
+
+```shell
+sudo vi /usr/local/opt/jenkins-lts/homebrew.mxcl.jenkins-lts.plistg
+```
+
+Locate the line:
+
+```shell
+--httpPort=8080
+```
+
+Change `8080` to the desired port number.
+
+* To access Jenkins, open a web browser and enter the following URL:
+
+```plaintext
+http://localhost:8080
+```
+
+If you changed the port number in the previous step, replace `8080` with the
+new port number.
+
+* On the Jenkins setup wizard page, you need to unlock Jenkins. To obtain the
+
+  initial admin password, navigate to the following path in your terminal:
+
+```shell
+sudo cat /Users/Shared/Jenkins/Home/secrets/initialAdminPassword
+```
+
+Copy the password and paste it into the setup wizard.
+
+* Follow the on-screen instructions to complete the installation and set
+
+  up your Jenkins instance.
+
+Get ready to unleash the power of Jenkins on your macOS machine
