 # goset
 
+One would argue that implementing set in go is easy. Thus, a library for a set is unnecessary. I agree, but if you have
+to implement it over and over again for many projects, it becomes tedious. So, I wrote a simple library, hoping it would
+save me a few lines in my projects.
+
+As any other go library, you can install it by
+```shell
+go get gitea.suyono.dev/suyono/goset
+```
