+Data structure and Algorithm (DSA)
+
+## Contribution Guidelines
+### 1. Folders or files naming
+The folder or file should have the below conditions:
+- The name should be in lower case.
+- The word should be separate with a **dash(-)**.
+- It can only contain **dash(-)** it cannot have other specific characters.
+- A new file should add to the **index(README.md)**.
+For example:
+```
+DSA
+  | searching
+    | readme.md -> should create an readme for the index
+    | c-or-cpp
+      | linear-search.cpp
+      | binary-search.cpp
+    | python
+      | linear-search.py
+      | binary-search.py
+    | csharp
+      | linear-search.cs
+      | binary-search.cs
+```
+### 2. Naming Convention
+The programming should keep the naming convention rule of each programming language
