# Getting Up to Speed With Go

Probably the most useful resoure I found was the [Tour of Go](https://tour.golang.org/).
It's easy to understand and teaches you all you need to know.

# Making a web api

> We need to memorize the `Handler` interface.

>     type Handler interface {
>         ServerHTTP(ResponseWriter, *Request)
>     }


# `godoc` [^golang-godoc]

> Godoc parses Go source code - including comments - and produces documentation as HTML or plain
> text.
> The end result is documentation tightly coupled with the code it documents.
> For example, through godoc's web interface [which is at <http://localhost:6060> by default] you can
> navigate from a function's documentation to its implementation with one click.

## Installing godoc // `command not found: godoc`

```bash
go get golang.org/x/tools/cmd/godoc
```
