+
+I made this simple website as a fun project to help me understand better: algorithms and data structures. And also to have some practice in: Java, JavaScript, CSS, HTML and responsive web design(RWD). If you discover some errors in the code or typos I haven't noticed please just let me know or feel free to contribute with Github, fork the project and make a pull request :)
+
+Sections are divided into:
+
+  - Big o cheat sheets
+  - intro
+  - big o notation
+  - data structures
+  - algorithms
+
+### Tech
