+# Small projects with Elegant code base
+We have been seeing such questions in Rust forums for a long time: 
+
+- What projects would you recommend to a Rust beginner?
+- Looking for small projects with an elegant code base
+- Codes that is easy to read and learn
+
+So, collecting relative resourses and representing in _Rust By Practice_ seems not a bad idea.

+Tutorial [`https://www.philippflenker.com/hecto/`](https://www.philippflenker.com/hecto/) will lead you to build a text editor from scratch.
