 In a main function, create a webserver using the `ListenAndServe()` function. This server should have at least one endpoint that accepts a parameter and returns it in a response. An example of a finished exercise in in [ex-1-server](ex-1-servers/server.go)

-_ *NOTE*: `ListenAndServe()` is great for prototyping and non-production development. When you are building out your services, make sure you have security in mind. Use a custom `mux`. We will learn more aabout security best practices later on in the course. Check out [Reliable Webservices](../reliable-webservice-go/README.md).

+## [Exercise 2](/ex-2-web-frameworks/framework.go) Build a Server Using an opensource Framework
 
 The [Standard Library](https://pkg.go.dev/net/http) provides all the functionality needed to build a robust web server, but sometimes, instead of building out your own infrastructre, there is a benefit to adopting an opensource frameworks at the backbone of your server infrastructure. This exercise is you chance to experiment with some popular Go web frameworks.
 
-*Instructions:* Pick a web frame work and implement a server that can accept a username at add it to the database. Use the provided webframeworks.go file to implement this server and add the username top the database using the provided functions. Add logic to handle duplicate usernames, empty username parameters, or any additional error cases. An example of the finished exercise using the [Chi]() framework is in the directory [ex-2-webframeworks/framework.go](/ex-2-webframeworks/framework.go)
+_Instructions:_ Pick a web framework and implement a server that can accept a username, validate it, and print the username to standard out. Add logic to handle duplicate usernames, empty username parameters, or any additional error cases. When a username is accepted and printed to standard out return a 200 class status code. If the parameter is empty or invalid return a 400 class error code. Handle any other errors. _We will connect this server to a database in the Day 2 exercises_

 _*Note:* you do not have to do this with a web framework. Feel free to use the standard library `net/http` tooling if you are more comfortable. The opstins for using a web framework are just to try you hand at evaluating popular opensource tools. But just like adding any tool to your software start there are risks and rewards._
 
 Here are some examples of opensource frameworks:
-- [Chi](https://github.com/go-chi/chi)
-- [Gin](https://github.com/gin-gonic/gin) <!-- uses it own context that predates context.Context-->
-- [Fiber](https://github.com/gofiber/fiber) <!-- uses fasthhtp -->

 Using the [httptest](https://pkg.go.dev/net/http/httptest#example-ResponseRecorder) package add some tests for at least one of our newly created endpoints. You should have one test that checks for a 200s class error and one that tests for a 400s class error. Add additional test validations as time allows.
 
 Here are some examples of tests for the above opensource frameworks.
