+# NAME
+HOME/.docker/confg.json - Default Docker configuration file
+
+# INTRODUCTION
+
+By default, the Docker command line stores its configuration files in a
+directory called `.docker` within your `HOME` directory.  Docker manages most of
+the files in the configuration directory and you should not modify them.
+However, you *can modify* the `config.json` file to control certain aspects of
+how the `docker` command behaves.
+
+Currently, you can modify the `docker` command behavior using environment
+variables or command-line options. You can also use options within
+`config.json` to modify some of the same behavior. When using these
+mechanisms, you must keep in mind the order of precedence among them. Command
+line options override environment variables and environment variables override
+properties you specify in a `config.json` file.
+
+The `config.json` file stores a JSON encoding of several properties:
+
+* The `HttpHeaders` property specifies a set of headers to include in all messages
+sent from the Docker client to the daemon. Docker does not try to interpret or
+understand these header; it simply puts them into the messages. Docker does not
+allow these headers to change any headers it sets for itself.
+
+* The `psFormat` property specifies the default format for `docker ps` output.
+When the `--format` flag is not provided with the `docker ps` command,
+Docker's client uses this property. If this property is not set, the client
+falls back to the default table format. For a list of supported formatting
+directives, see **docker-ps(1)**.
+
+* The `detachKeys` property specifies the default key sequence which
+detaches the container. When the `--detach-keys` flag is not provide
+with the `docker attach`, `docker exec`, `docker run` or `docker
+start`, Docker's client uses this property. If this property is not
+set, the client falls back to the default sequence `ctrl-p,ctrl-q`.
+
+
+* The `imagesFormat` property  specifies the default format for `docker images`
+output. When the `--format` flag is not provided with the `docker images`
+command, Docker's client uses this property. If this property is not set, the
+client falls back to the default table format. For a list of supported
+formatting directives, see **docker-images(1)**.
+
+You can specify a different location for the configuration files via the
+`DOCKER_CONFIG` environment variable or the `--config` command line option. If
+both are specified, then the `--config` option overrides the `DOCKER_CONFIG`
+environment variable:
+
+    docker --config ~/testconfigs/ ps
+
+This command instructs Docker to use the configuration files in the
+`~/testconfigs/` directory when running the `ps` command.
+
+## Examples
+
+Following is a sample `config.json` file:
+
+    {
+      "HttpHeaders": {
+        "MyHeader": "MyValue"
+      },
+      "psFormat": "table {{.ID}}\\t{{.Image}}\\t{{.Command}}\\t{{.Labels}}",
+      "imagesFormat": "table {{.ID}}\\t{{.Repository}}\\t{{.Tag}}\\t{{.CreatedAt}}",
+      "detachKeys": "ctrl-e,e"
+    }
