+## Attributes of high-quality computer code
+
+**Quality** of computer code can be seen as a **group of various attributes**.
+
+High-quality computer code should be:
+
+1. <font color="#A52A2A">**Versioned**</font>: incremental code
+2. <font color="#FFA500">**Well-written**</font> (formatted, documented, commented): easy to read by a human
+3. <font color="#008931">**Tested**</font>: extensively tested code
