If you're looking for the @imageengine/angular package readme, you can find it on the projects folder.
This workspace only contains, as of now, the ngx-imageengine component.
To publish that project it needs to be built first.
You can run npm run publish that does it in a single command, or manually with the following steps.
Run ng build from the workspace root directory to build the projects. The build artifacts will be stored in the dist/ directory.
(remember to bump the version of the desired project on the project's package.json before building a new version)
After building the project(s) the builds will be stored in dist/. To publish to NPM navigate to the project folder (e.g: cd dist/ngx-imageengine) and from there do npm publish --access public.
The test should be run from the project(s) folder themselves and not from the root workspace (e.g: cd dist/ngx-imageengine followed by npm run test)
