The Go SDK contains packages for interacting with most aspects of the stellar ecosystem. In addition to generally useful, low-level packages such as keypair (used for creating stellar-compliant public/secret key pairs), the Go SDK also contains code for the server applications and client tools written in go.
Godoc reference
The most accurate and up-to-date reference information on the Go SDK is found within godoc. The godoc.org service automatically updates the documentation for the Go SDK everytime github is updated. The godoc for all of our packages can be found at (https://godoc.org/github.com/stellar/go).
