6# Alternative (more granular) approach to a DNS library
7
8> Less is more.
9
10Complete and usable DNS library. All Resource Records are supported, including the DNSSEC types.
11It follows a lean and mean philosophy. If there is stuff you should know as a DNS programmer there
12isn't a convenience function for it. Server side and client side programming is supported, i.e. you
13can build servers and resolvers with it.
14
15We try to keep the "master" branch as sane as possible and at the bleeding edge of standards,
16avoiding 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.

95# Building
96
97This library uses Go modules and uses semantic versioning. Building is done with the `go` tool, so
98the following should work:
99
100    go get github.com/miekg/dns
101    go build github.com/miekg/dns
102
103## Examples
104
105A short "how to use the API" is at the beginning of doc.go (this also will show when you call `godoc
106github.com/miekg/dns`).
107
108Example programs can be found in the `github.com/miekg/exdns` repository.
