+- It is now possible to specify "sources" for packages in a `[sources]` section in Project.toml.

 Typically it is not needed to manually add entries to the `[deps]` section; this is instead
 handled by Pkg operations such as `add`.
 
+### The `[sources]` section
+
+Specifiying a path or repo (+ branch) for a dependency is done in the `[sources]` section.
+These are especially useful for controlling unregistered dependencies without having to bundle a
+corresponding manifest file.
+
+```toml
+[sources]
+Example = {url = "https://github.com/JuliaLang/Example.jl", rev = "custom_branch"}
+SomeDependency = {path = "deps/SomeDependency.jl"}
+```
+
+Note that this information is only used when this environment is active, i.e. it is not used if this project is a package that is being used as a dependency.

 For example, if both `Manifest-v1.11.toml` and `Manifest.toml` exist, Julia 1.11 will prioritize using `Manifest-v1.11.toml`.
 However, Julia versions 1.10, 1.12, and all others will default to using `Manifest.toml`.
 This feature allows for easier management of different instantiated versions of dependencies for various Julia versions.

+Note that there can only be one `Project.toml` file. While `Manifest-v{major}.{minor}.toml` files are not automatically
 created by Pkg, users can manually rename a `Manifest.toml` file to match
 the versioned format, and Pkg will subsequently maintain it through its operations.
