+##Simple HTTP hello world:
+
+If you want to handle things at the level of just
+HTTP requests and responses, this is a simple example
+of returning "Hello <name>!" only on "/hello/<name>" paths,
+and a 404 on all others.
+
+Put it in a file called `http.jl` and then use the command `julia http.jl` to run it.
+If you open `localhost:8000/hello/user`, you'll get to see the server say hello.

-Middleware using `Meddle`:
+##Middleware using `Meddle`:
+
+This is an example of using our middleware framework, Meddle.
+It puts each request through a "stack" of handlers,
+each of which can modify the request and/or response objects.
+
+This particular example is a file server.
+It will serve files from the directory you run it in,
+and respond with `404`s if you give an invalid path.
+
+Put it in a file called `meddle.jl` and then use the command `julia meddle.jl` to run it.
+If you run it from inside your `webstack.jl` folder,
+you could then open `localhost:8000/examples/meddle.jl` to have it serve its own code to you.
