-## Unit testing 
-
-To run your unit tests, run the following command in the project root directory (ie. where the file `settings.gradle` is located):
+## Building
 
+To compile and assemble the plugin, run the following command in the project root directory:
 ```bash
-./gradlew check
+make assemble
 ```
 
-## Testing and debugging
-
-To build and test the plugin during development, configure a local Nextflow build with the following steps:
+## Unit testing
 
-1. Clone the Nextflow repository in your computer into a sibling directory:
-    ```bash
-    git clone --depth 1 https://github.com/nextflow-io/nextflow ../nextflow
-    ```
-  
-2. Configure the plugin build to use the local Nextflow code:
-    ```bash
-    echo "includeBuild('../nextflow')" >> settings.gradle
-    ```
-  
-   (Make sure to not add it more than once!)
-
-3. Compile the plugin alongside the Nextflow code:
-    ```bash
-    make assemble
-    ```
-
-4. Run Nextflow with the plugin, using `./launch.sh` as a drop-in replacement for the `nextflow` command, and adding the option `-plugins nf-hello` to load the plugin:
-    ```bash
-    ./launch.sh run nextflow-io/hello -plugins nf-hello
-    ```
+To run your unit tests, run the following command in the project root directory:
+```bash
+make test
+```
 
-## Testing without Nextflow build
+## Testing with Nextflow
 
-The plugin can be tested without using a local Nextflow build using the following steps:
+The plugin can be tested without a local Nextflow installation:
 
-1. Build the plugin: `make buildPlugins`
-2. Copy `build/plugins/<your-plugin>` to `$HOME/.nextflow/plugins`
-3. Create a pipeline that uses your plugin and run it: `nextflow run ./my-pipeline-script.nf`
+1. Build and install the plugin to your local Nextflow installation: `make install`
+2. Create a pipeline that uses your plugin and run it: `nextflow run ./my-pipeline-script.nf`
 
 ## Package, upload, and publish
 
-The project should be hosted in a GitHub repository whose name matches the name of the plugin, that is the name of the directory in the `plugins` folder (e.g. `nf-hello`).
-
 Follow these steps to package, upload and publish the plugin:
 
-1. Create a file named `gradle.properties` in the project root containing the following attributes (this file should not be committed to Git):
+1. In `build.gradle` make sure that
+    * `github.repository` matches the repository of the plugin
+    * `github.indexUrl` points to your fork of the plugins index repository.
+
+2. Create a file named `$HOME/.gradle/gradle.properties`, where $HOME is your home directory. Add the following properties:
 
-   * `github_organization`: the GitHub organisation where the plugin repository is hosted.
-   * `github_username`: The GitHub username granting access to the plugin repository.
-   * `github_access_token`: The GitHub access token required to upload and commit changes to the plugin repository.
-   * `github_commit_email`: The email address associated with your GitHub account.
+    * `github_username`: The GitHub username granting access to the plugin repository.
+    * `github_access_token`: The GitHub access token required to upload and commit changes to the plugin repository.
+    * `github_commit_email`: The email address associated with your GitHub account.
 
-2. Use the following command to package and create a release for your plugin on GitHub:
-    ```bash
-    ./gradlew :plugins:nf-hello:upload
-    ```
+3. Use the following command to package and create a release for your plugin on GitHub: `make release`
 
-3. Create a pull request against [nextflow-io/plugins](https://github.com/nextflow-io/plugins/blob/main/plugins.json) to make the plugin accessible to Nextflow.
+4. Create a pull request against [nextflow-io/plugins](https://github.com/nextflow-io/plugins/blob/main/plugins.json) to

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
