 In a nutshell, Jenkins is the leading open-source automation server.
 Built with Java, it provides over 2,000 [plugins](https://plugins.jenkins.io/) to support automating virtually anything,
 so that humans can spend their time doing things machines cannot.

+# Getting Started (Development)
+
+To build and run Jenkins locally from source, follow these steps:
+
+### 1. Clone the Repository
+
+```bash
+git clone https://github.com/jenkinsci/jenkins.git
+cd jenkins
+```
+### 2. Build the Project
+Use Maven to compile and package Jenkins:
+```bash
+mvn clean install -DskipTests
+```
+To run tests during the build, omit the ```-DskipTests``` flag.
+> The build may take several minutes, depending on your system and internet speed.
+
+### 3. Run Jenkins
+Once built, you can launch Jenkins using:
+```bash
+java -jar war/target/jenkins.war
+```
+Jenkins will start on http://localhost:8080 by default.
+> ⚠️ Make sure Java 11 or higher and Apache Maven are installed and available in your PATH.
+
+### 4. Developer Tips
+- Use ```mvn hpi:run``` to start Jenkins in development mode with hot-reload support for plugins.
+- Logs will be shown in the console to help with debugging.
+- You can access the initial admin password in:
+```bash
+~/.jenkins/secrets/initialAdminPassword
+```
+If port 8080 is in use, run Jenkins on another port:
+```bash
+java -jar war/target/jenkins.war --httpPort=9090
+```
+
+### 5. Troubleshooting
+OutOfMemoryError: Try increasing memory limits:
+```bash
+MAVEN_OPTS="-Xmx2g -XX:MaxPermSize=512m"
+```
+- Permission issues on Unix/macOS: use sudo or ensure correct ownership of files.
+- Build fails on tests: Try a clean rebuild:
+```bash
+mvn clean install -DskipTests
+```
+### 6. Useful Commands
+
+| Task                | Command                         |
+| ------------------- | ------------------------------- |
+| Clean build         | `mvn clean install -DskipTests` |
+| Run with tests      | `mvn clean install`             |
+| Start in dev mode   | `mvn hpi:run`                   |
+| Run unit tests only | `mvn test`                      |
+| Build WAR only      | `mvn package -DskipTests`       |
