# Vendored Dependencies
Dependencies are almost all vendored in at the standard Go `/vendor` path. This allows
people to build go-ethereum using the standard toolchain without any particular package
manager. It also plays nicely with `go get`, not requiring external code to be relied on.
The one single dependent package missing from `vendor` is `golang.org/x/net/context`. As
this is a package exposed via public library APIs, it must not be vendored as dependent
code woulnd't be able to instantiate.
To allow reproducible builds of go-ethereum nonetheless that don't need network access
during build time to fetch `golang.org/x/net/context`, a version was copied into our repo
at the very specific `/build/_vendor` path, which is added automatically by all CI build
scripts and the makefile too.
# Debian Packaging
Tagged releases and develop branch commits are available as installable Debian packages
