6 # Alternative (more granular) approach to a DNS library
7
8 > Less is more.
9
10 Complete and usable DNS library. All Resource Records are supported, including the DNSSEC types.
11 It follows a lean and mean philosophy. If there is stuff you should know as a DNS programmer there
12 isn't a convenience function for it. Server side and client side programming is supported, i.e. you
13 can build servers and resolvers with it.
14
15 We try to keep the "master" branch as sane as possible and at the bleeding edge of standards,
16 avoiding breaking changes wherever reasonable. We support the last two versions of Go.
17
18 # Goals
19
20 * KISS;
21 * Fast;
22 * Small API. If it's easy to code in Go, don't make a function for it.

94 # Building
95
96 Building is done with the `go` tool. If you have setup your GOPATH correctly, the following should
97 work:
98
99     go get github.com/miekg/dns
100     go build github.com/miekg/dns
101
102 ## Examples
103
104 A short "how to use the API" is at the beginning of doc.go (this also will show when you call `godoc
105 github.com/miekg/dns`).
106
107 Example programs can be found in the `github.com/miekg/exdns` repository.
