+
+## Installation
+
+1. Clone the repository:
+    ```sh
+    git clone https://github.com/bcExpt1123/java-alda.git
+    ```
+2. Navigate to the project directory:
+    ```sh
+    cd java-alda
+    ```
+
+## Usage
+
+Each algorithm and data structure has its own folder. Navigate to the folder of the algorithm or data structure you want to use and compile the Java file:
+```sh
+javac FileName.java
+```
+Run the compiled Java file:
+```sh
+java FileName
+```
