The concept of dependencies is fundamental to Unity’s Package Manager behavior.
A dependency is a package that your project or another package needs to work.

| Dependency and resolution | Learn about the different types of dependencies and how Package Manager resolves them. |
| Package version conflict and resolution | Learn how Package Manager resolves package version conflicts when computing a compatible set of packages. |
