+# Generic Makefile for building and packaging a Nextcloud app which uses npm and
+# Composer.
+#
+# Dependencies:
+# * make
+# * which
+# * curl: used if phpunit and composer are not installed to fetch them from the web
+# * tar: for building the archive
+# * npm: for building and testing everything JS
+#
+# If no composer.json is in the app root directory, the Composer step
+# will be skipped. The same goes for the package.json which can be located in
+# the app root or the js/ directory.
+#
+# The npm command by launches the npm build script:
+#
+#    npm run build
+#
+# The npm test command launches the npm test script:
+#
+#    npm run test
+#
+# The idea behind this is to be completely testing and build tool agnostic. All
+# build tools and additional package managers should be installed locally in
+# your project, since this won't pollute people's global namespace.
+#
+# The following npm scripts in your package.json install and update the bower
+# and npm dependencies and use gulp as build system (notice how everything is
+# run from the node_modules folder):
+#
+#    "scripts": {
+#        "test": "node node_modules/gulp-cli/bin/gulp.js karma",
+#        "prebuild": "npm install && node_modules/bower/bin/bower install && node_modules/bower/bin/bower update",
+#        "build": "node node_modules/gulp-cli/bin/gulp.js"

+# Secondary Mail
+Place this app in **nextcloud/apps/**
+
+## Building the app
+
+The app can be built by using the provided Makefile by running:
+
+    make
+
+This requires the following things to be present:
+* make
+* which
+* tar: for building the archive
+* curl: used if phpunit and composer are not installed to fetch them from the web
+* npm: for building and testing everything JS, only required if a package.json is placed inside the **js/** folder
+
+The make command will install or update Composer dependencies if a composer.json is present and also **npm run build** if a package.json is present in the **js/** folder. The npm **build** script should use local paths for build systems and package managers, so people that simply want to build the app won't need to install npm libraries globally, e.g.:
+
+**package.json**:
+```json
+"scripts": {
+    "test": "node node_modules/gulp-cli/bin/gulp.js karma",
+    "prebuild": "npm install && node_modules/bower/bin/bower install && node_modules/bower/bin/bower update",
+    "build": "node node_modules/gulp-cli/bin/gulp.js"
+}
+```
+
+
+## Publish to App Store
+
+First get an account for the [App Store](http://apps.nextcloud.com/) then run:
+
+    make && make appstore
+
+The archive is located in build/artifacts/appstore and can then be uploaded to the App Store.
+
+## Running tests
+You can use the provided Makefile to run all tests by using:
+
+    make test
+
+This will run the PHP unit and integration tests and if a package.json is present in the **js/** folder will execute **npm run test**
+
+Of course you can also install [PHPUnit](http://phpunit.de/getting-started.html) and use the configurations directly:
+
+    phpunit -c phpunit.xml
+
+or:
+
+    phpunit -c phpunit.integration.xml
+
+for integration tests
