+## Introduction
+ - SDKMAN is a command-line tool for managing software development kits (SDKs).
+ - It simplifies the process of installing, managing, and switching between different SDK versions.
+ - It supports popular SDKs like Java, Maven, Gradle,  Groovy, Scala, Kotlin, and more. 
+ {{< admonition type=tip  open=true >}}
+    Personally I use for maven gradle and Java (JDK)
+ {{< /admonition >}}
+ - SDKMAN provides a centralized repository of SDKs with various versions.
+ - It automates the installation and configuration of SDKs, saving developers time and effort.
+ - Developers can easily list available SDKs, install specific versions, and switch between them seamlessly.
+## Getting Started with SDKMAN
+
+  ### Installing SDKMAN on your system:
+ - Open your terminal or command prompt. for windows run from `gitbash`
+ - Run the following command to download and install SDKMAN: 
+      ```sh
+        curl -s "https://get.sdkman.io" | bash
+      ``` 
+  ### Setting up SDKMAN environment variables:
+ - After the installation completes, run the following command to initialize SDKMAN:
+      ```sh
+        source "$HOME/.sdkman/bin/sdkman-init.sh"
+      ```
+  ### Verifying the installation:
+ - To verify that SDKMAN is installed correctly, run the following command:
+      ```sh
+        sdk version
+      ```
+ - It should display the version of SDKMAN installed.
+
+## Managing SDKs with SDKMAN
+
+To effectively manage SDKs with SDKMAN, follow these steps:
+
+### Listing available SDKs and versions:
+ - To view the available SDKs and their versions, use the following command:
+    ```sh
+    sdk list <sdk>
+    ```
+ - Example for Java JDK:
+    ```sh
+    sdk list java
+    ```
+    This command will display a list of available Java JDK versions.
+
+### Installing SDKs using SDKMAN:
+ - To install a specific SDK version, use the following command:
+    ```sh
+    sdk install <sdk> <version>
+    ```
+ - Example for Java JDK:
+    ```sh
+    sdk install java 17.0.5-zulu
+    ```    
+    This command will install Java JDK version **17.0.5-zulu**.
+
+### Switching between different SDK versions:
+ - To switch between different SDK versions, use the following command:
+    ```sh
+    sdk use <sdk> <version>
+    ```
+ - Example for Java JDK: suppose if you installed already `sdk install java 11.0.17-zulu`
+    ```sh
+    sdk use java 11.0.17-zulu
+    ```    
+    This command will switch Java JDK version to **11.0.17-zulu**.
+
+ ### Setting a default SDK version:
+
+SDKMAN simplifies setting a default SDK version for each candidate, applying it automatically when you start a new session or open a terminal. Use the "default" command to set it effortlessly.
+
+ - Setting a default SDK version:
+    ```sh
+    sdk default <sdk> <version>
+    ```
+ - Example for setting the default Java JDK version:
+    ```sh
+    sdk default java 17.0.5-zulu
+    ```    
+    This command will set java jdk version **17.0.5-zulu** as default.    
+### Checking the current default SDK version:
+ - To check the current default version for an SDK candidate, use the following command:
+    ```sh
+    sdk default <sdk>
+    ```
+ - Example for checking the default Java JDK version:
+    ```sh
+    sdk default java
+    ```
+    This command will display the currently set default version of Java JDK.
+
+### Removing SDKs with ease:
+ - To remove an installed SDK, use the following command:
+    ```sh
+    sdk uninstall <sdk> <version>
+    ```
+ - Example for Java JDK :
+    ```sh
+    sdk uninstall java 11.0.17-zulu
+
+    ```
+    This command will uninstall Java JDK version **11.0.17-zulu**.
+
+
