If you are a casual user with no development experience, and no preliminary knowledge of go, building from source is probably not a good solution for you.
## Build the development environment
## Configure the development environment
The first prerequisite of properly building distribution targets is to have a Go
development environment setup. Please follow [How to Write Go Code](https://golang.org/doc/code.html)
for proper setup. If done correctly, you should have a GOROOT and GOPATH set in the
environment.
If a Go development environment is setup, one can use `go get` to install the
`registry` command from the current latest:
Next, fetch the code from the repository using git:
go get github.com/distribution/distribution/cmd/registry
git clone https://github.com/distribution/distribution
cd distribution
The above will install the source repository into the `GOPATH`.
If you are planning to create a pull request with changes, you may want to clone directly from your [fork](https://help.github.com/en/articles/about-forks).
## Build and run from source
First, build the binaries:
$ make
+ bin/registry
+ bin/digest
+ bin/registry-api-descriptor-template
+ binaries
Now create the directory for the registry data (this might require you to set permissions properly)

### Repeatable Builds
### Build reference
For the full development experience, one should `cd` into
`$GOPATH/src/github.com/distribution/distribution`. From there, the regular `go`
commands, such as `go test`, should work per package (please see
[Developing](#developing) if they don't work).
The regular `go` commands, such as `go test`, should work per package.
A `Makefile` has been provided as a convenience to support repeatable builds.
Please install the following into `GOPATH` for it to work:
go get github.com/golang/lint/golint
Once these commands are available in the `GOPATH`, run `make` to get a full
build:
Run `make` to build the binaries:
$ make
+ clean
+ fmt
+ vet
+ lint
+ build

The above provides a repeatable build using the contents of the vendor
directory. This includes formatting, vetting, linting, building,
testing and generating tagged binaries. We can verify this worked by running
directory. We can verify this worked by running
the registry binary generated in the "./bin" directory:
$ ./bin/registry --version
./bin/registry github.com/distribution/distribution v2.0.0-alpha.2-80-g16d8b2c.m
Run `make test` to run all of the tests.
Run `make validate` to run the validators, including the linter and vendor validation. You must have docker with the buildx plugin installed to run the validators.
### Optional build tags
Optional [build tags](http://golang.org/pkg/go/build/) can be provided using
