+[![Go Report Card](https://goreportcard.com/badge/github.com/volker-raschek/docker-hub-description-updater)](https://goreportcard.com/report/github.com/volker-raschek/docker-hub-description-updater)

+
+By specifying the login data for hub.docker.com you can update the short and
+long description of a docker repository.
+
+## Usage
+
+Several options are available to update the descriptions. Either based on
+Markdown files or as a normal string, which is passed as argument when calling.
+The examples below describe two ways, the binary and container based way.
+
+### Example 1: Update full description of the repository with a Markdown file
+
+```bash
+dhdu \
+  -user=<username> \
+  -password=<password> \
+  -namespace=<namespace> \
+  -repository=<repository> \
+  -full-description-file=./README.md
+```
+
+```bash
+docker run \
+  --rm \
+  --volume $(pwd):/workspace \
+    volkerraschek/dhdu \
+      -user=<username> \
+      -password=<password> \
+      -namespace=<namespace> \
+      -repository=<repository> \
+      -full-description-file=./README.md
+```
+
+### Example 2: Update full description of the repository over an argument
+
+```bash
+dhdu -user=<username> \
+     -password=<password> \
+     -namespace=<namespace> \
+     -repository=<repository> \
+     -full-description="My awesome description"
+```
+
+```bash
+docker run \
+  --rm \
+  --volume $(pwd):/workspace \
+    volkerraschek/dhdu \
+      -user=<username> \
+      -password=<password> \
+      -namespace=<namespace> \
+      -repository=<repository> \
+      -full-description="My awesome description"
+```
+
+## Compiling the source code
+
+There are two different ways to compile dhdu from scratch. The easier ways is
+to use the pre-defined container image in the Makefile, which has included all
+dependancies to compile dhdu. Alternatively, if all dependencies are met,
+dhdu can also be compiled without the container image. Both variants are
+briefly described.
+
+### Compiling the source code via container image
+
+To compile dhdu via container image it's necessary, that a container runtime
+is installed. In the Makefile is predefined docker, but it's can be also used
+podman. Execute `make container-run/dhdu` to start the compiling process.
+
+```bash
+make container-run/dhdu
+```
+
+#### Compiling the source code without container image
+
+Make sure you have installed go >= v1.12. Execute `make dhdu` to compile
+dhdu without a container-image. There should be a similar output as when
+compiling dhdu via the container image.
