+Docker images for building Apache CloudStack SystemVM Templates.
+
+This will give portable, immutable and reproducable mechanism to build templates for releases. A very good candidate to be used by the Jenkins slaves of the project.

+## Build templates
+
+Building SystemVM templates with the Docker container is rather easy, a few steps are required:
+
+### Pull Docker images
+
+Let's assume we want to build templates based on Packer. We pull that image first:
+
+    docker pull khos2ow/cloudstack-systemvm-builder:packer
+
+You need to replace `packer` tag by `veewee` if you are building templates for CloudStack before `4.11.x.y`.
+
+### Build local repository
+
+You can clone the CloudStack source code from repository locally on your machine and build templates against that.
+
+#### Clone Apache CloudStack source code
+
+The first step required is to clone the CloudStack source code somewhere on the filesystem, in `/tmp` for example:
+
+    git clone https://github.com/apache/cloudstack.git /tmp/cloudstack
+
+Now that you have done so we can continue.
+
+#### Build templates of local repository
+
+Now that we have cloned the CloudStack source code locally, we can build templates by mapping `/tmp` into `/mnt/build` in the container. (Note that the container always expects the `cloudstack` code exists in `/mnt/build` path.)
+
+    docker run \
+        -v /tmp:/mnt/build \
+        khos2ow/cloudstack-systemvm-builder:packer TODO [ARGS...]
+
+Or if your local cloudstack folder has other name, you need to map it to `/mnt/build/cloudstack`.
+
+    docker run \
+        -v /tmp/cloudstack-custom-name:/mnt/build/cloudstack \
+        khos2ow/cloudstack-systemvm-builder:packer TODO [ARGS...]
+
+After the build has finished the *various formats* templates are available in */tmp/cloudstack/tools/appliance/dist* on the host system.
+
+### Build remote repository
+
+Also you can build templates of any remote repository without the need to manually clone it first. You only need to specify git remote and git ref you intend to build from.
+
+#### Build templates of remote repository
+
+Now let's assume we want to build templates of `HEAD` of `master` branch from https://github.com/apache/cloudstack repository, we build templates by mapping `/tmp` into `/mnt/build` in the container. The container will clone the repository (defined by `--git-remote` flag) and check out the REF (defined by `--git-ref` flag) in `/mnt/build/cloudstack` inside the container and can be accessed from `/tmp/cloudstack` from the host machine.
+
+    docker run \
+        -v /tmp:/mnt/build \
+        khos2ow/cloudstack-systemvm-builder:packer \
+            --git-remote https://github.com/apache/cloudstack.git \
+            --git-ref master \
+            TODO [ARGS...]
+
+Note that any valid git Refspec is acceptable, such as:
+
+- `refs/heads/<BRANCH>` to build specified Branch
+- `<BRANCH>` short version of build specified Branch
+- `refs/pull/<NUMBER>/head` to build specified GitHub Pull Request
+- `refs/merge-requests/<NUMBER>/head` to build specified GitLab Merge Request
+- `refs/tags/<NAME>` to build specified Tag
+
+After the build has finished the *various formats* templates are available in */tmp/cloudstack/tools/appliance/dist* on the host system.
+
+## Building tips
+
+Check the following tips when using the builder:
+
+### Maven cache
+
+You can provide Maven cache folder (`~/.m2`) as a volume to the container to make it run faster.
+
+    docker run \
+        -v /tmp:/mnt/build \
+        -v ~/.m2:/root/.m2 \
+        khos2ow/cloudstack-systemvm-builder:packer TODO [ARGS...]
+
+### Adjust host owner permission
+
+**TODO** Builder container in some cases (e.g. using `--use-timestamp` flag) may change the file and directory owner shared from host to container (through volume) and it will create `dist` directory which holds the final artifacts. You can provide `USER_ID` (mandatory) and/or `USER_GID` (optional) from host to adjust the owner from whitin the container.
+
+This is specially useful if you want to use this image in Jenkins job and want to clean up the workspace afterward. By adjusting the owner, you won't need to give your Jenkins' user `sudo` privilege to clean up.
+
+    docker run \
+        -v /tmp:/mnt/build \
+        -e "USER_ID=$(id -u)" \
+        -e "USER_GID=$(id -g)" \
+        khos2ow/cloudstack-systemvm-builder:packer  TODO [ARGS...]
+
+## Builder help
+
+To see all the available options you can pass to `docker run ...` command:
+
+    docker run \
+        -v /tmp:/mnt/build \
+        khos2ow/cloudstack-systemvm-builder:packer --help
