 Adding a new server `TYPE` can vary due to the complexity of obtaining and configuring each type; however, the addition of any server type includes at least the following steps:

+## Using development copy of mc-image-helper
+
+In the cloned copy of [`mc-image-helper`](https://github.com/itzg/mc-image-helper), create an up-to-date snapshot build of the tgz distribution using:
+
+```shell
+./gradlew distTar
+```
+
+Assuming [http-server](https://www.npmjs.com/package/http-server) is installed globally, start a static web server using:
+
+```shell
+http-server ./build/distributions -p 0
+```
+
+Note the port that was selected by http-server and pass the build arguments, such as:
+
+```shell
+--build-arg MC_HELPER_VERSION=1.8.1-SNAPSHOT \
+--build-arg MC_HELPER_BASE_URL=http://host.docker.internal:8080
+```
+
+Now the image can be built like normal and it will install mc-image-helper from the locally built copy.

 ## Multi-base-image variants
 
 Several base-image variants are maintained in order to offer choices in JDK provider and version. The variants are maintained in their respective branches:

 For some cases, if e.g. after removing mods, it could be necessary to startup minecraft with an additional `-D` parameter like `-Dfml.queryResult=confirm`. To address this you can use the environment variable `JVM_DD_OPTS`, which builds the params from a given list of values separated by space, but without the `-D` prefix. To make things running under systems (e.g. Plesk), which doesn't allow `=` inside values, a `:` (colon) could be used instead. The upper example would look like this:
