+[![Build Status](https://github.com/fsouza/go-dockerclient/workflows/Build/badge.svg)](https://github.com/fsouza/go-dockerclient/actions?query=branch:master+workflow:Build)
+[![GoDoc](https://img.shields.io/badge/api-Godoc-blue.svg?style=flat-square)](https://pkg.go.dev/github.com/fsouza/go-dockerclient)
+
+This package presents a client for the Docker remote API. It also provides
+support for the extensions in the [Swarm API](https://docs.docker.com/swarm/swarm-api/).
+
+This package also provides support for docker's network API, which is a simple
+passthrough to the libnetwork remote API.
+
+For more details, check the [remote API
+documentation](https://docs.docker.com/engine/api/latest/).
+
+## Difference between go-dockerclient and the official SDK
+
+Link for the official SDK: https://docs.docker.com/develop/sdk/
+
+go-dockerclient was created before Docker had an official Go SDK and is
+still maintained and active because it's still used out there. New features in
+the Docker API do not get automatically implemented here: it's based on demand,
+if someone wants it, they can file an issue or a PR and the feature may get
+implemented/merged.
+
+For new projects, using the official SDK is probably more appropriate as
+go-dockerclient lags behind the official SDK.
+
+When using the official SDK, keep in mind that because of how the its
+dependencies are organized, you may need some extra steps in order to be able
+to import it in your projects (see
+[#784](https://github.com/fsouza/go-dockerclient/issues/784) and
+[moby/moby#28269](https://github.com/moby/moby/issues/28269)).
+
+## Example
+
+```go
+package main
+
+import (
+	"fmt"
+
+	docker "github.com/fsouza/go-dockerclient"
+)
+
+func main() {
+	client, err := docker.NewClientFromEnv()
+	if err != nil {
+		panic(err)
+	}
+	imgs, err := client.ListImages(docker.ListImagesOptions{All: false})
+	if err != nil {
+		panic(err)
+	}
+	for _, img := range imgs {
+		fmt.Println("ID: ", img.ID)
+		fmt.Println("RepoTags: ", img.RepoTags)
+		fmt.Println("Created: ", img.Created)
+		fmt.Println("Size: ", img.Size)
+		fmt.Println("VirtualSize: ", img.VirtualSize)
+		fmt.Println("ParentId: ", img.ParentID)
+	}
+}
+```
+
+## Using with TLS
+
+In order to instantiate the client for a TLS-enabled daemon, you should use
+NewTLSClient, passing the endpoint and path for key and certificates as
+parameters.
+
+```go
+package main
+
+import (
+	"fmt"
+
+	docker "github.com/fsouza/go-dockerclient"
+)
+
+func main() {
+	const endpoint = "tcp://[ip]:[port]"
+	path := os.Getenv("DOCKER_CERT_PATH")
+	ca := fmt.Sprintf("%s/ca.pem", path)
+	cert := fmt.Sprintf("%s/cert.pem", path)
+	key := fmt.Sprintf("%s/key.pem", path)
+	client, _ := docker.NewTLSClient(endpoint, cert, key, ca)
+	// use client
+}
+```
+
+If using [docker-machine](https://docs.docker.com/machine/), or another
+application that exports environment variables `DOCKER_HOST`,
+`DOCKER_TLS_VERIFY`, `DOCKER_CERT_PATH`, `DOCKER_API_VERSION`, you can use
+NewClientFromEnv.
+
+
+```go
+package main
+
+import (
+	"fmt"
+
+	docker "github.com/fsouza/go-dockerclient"
+)
+
+func main() {
+	client, err := docker.NewClientFromEnv()
+	if err != nil {
+		// handle err
+	}
+	// use client
+}
+```
+
+See the documentation for more details.
+
+## Developing
+
+All development commands can be seen in the [Makefile](Makefile).
+
+Commited code must pass:
+
+* [golangci-lint](https://github.com/golangci/golangci-lint)
+* [go test](https://golang.org/cmd/go/#hdr-Test_packages)
+
+Running ``make test`` will run all checks, as well as install any required
+dependencies.
+
+## Modules
+
+go-dockerclient supports Go modules.
+
+If you're using dep, you can check the [releases
+page](https://github.com/fsouza/go-dockerclient/releases) for the latest
+release fully compatible with dep.
+
+With other vendoring tools, users need to specify go-dockerclient's
+dependencies manually.
+
+## Using with Docker 1.9 and Go 1.4
+
+There's a tag for using go-dockerclient with Docker 1.9 (which requires
+compiling go-dockerclient with Go 1.4), the tag name is ``docker-1.9/go-1.4``.
+
+The instructions below can be used to get a version of go-dockerclient that compiles with Go 1.4:
+
+```
+% git clone -b docker-1.9/go-1.4 https://github.com/fsouza/go-dockerclient.git $GOPATH/src/github.com/fsouza/go-dockerclient
+% git clone -b v1.9.1 https://github.com/docker/docker.git $GOPATH/src/github.com/docker/docker
+% go get github.com/fsouza/go-dockerclient
+```
