FAQ
Example:

- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Micropackages - as the name suggests - are micro packages with a tiny bit of reusable code, helpful particularly in WordPress development.
The aim is to have multiple packages which can be put together to create something bigger by defining only the structure.
Micropackages are maintained by BracketSpace.
