+### Inheriting a dependency from a workspace
+
+Dependencies can be inherited from a workspace by specifying the
+dependency in the workspace's [`[workspace.dependencies]`][workspace.dependencies] table.
+After that add it to the `[dependencies]` table with `dep.workspace = true`.
+
+The `workspace` key can be defined with:
+- [`optional`][optional]: Note that the`[workspace.dependencies]` table is not allowed to specify `optional`.
+- [`features`][features]: These are additive with the features declared in the `[workspace.dependencies]`
+
+The `workspace` key cannot be defined with:
+
+|                  |                    | 
+|------------------|--------------------|
+| `branch`         | `default-features` |
+| `git`            | `package`          |
+| `path`           | `registry`         |
+| `registry-index` | `rev`              |
+| `tag`            | `version`          |
+
+
+Dependencies in the `[dependencies]`, `[dev-dependencies]`, `[build-dependencies]`, and
+`[target."...".dependencies]` sections support the ability to reference the
+`[workspace.dependencies]` definition of dependencies.
+
+Example:
+```toml
+[dependencies]
+dep.workspace = true
+dep2 = { workspace = true, features = ["fancy"] }
+dep3 = { workspace = true, optional = true }
+dep4 = { workspace = true, optional = true, features = ["fancy"] }
+
+[build-dependencies]
+dep-build.workspace = true
+
+[dev-dependencies]
+dep-dev.workspace = true

-
-* RFC: [#2906](https://github.com/rust-lang/rfcs/blob/master/text/2906-cargo-workspace-deduplicate.md)
-* Tracking Issue: [#8415](https://github.com/rust-lang/cargo/issues/8415)
-* [Status](https://github.com/rust-lang/cargo/issues/8415#issuecomment-1112618913)
-* [Example Port](https://github.com/clap-rs/clap/pull/3719)
-
-### Testing notes
-
-Target audience for testing
-* Maintainer who has a workspace
-* *(optional)* Project depends on nightly toolchain
-
-In preparing to stabilize, we are wanting to better understand
-* If there were any pain points in porting your project
-* Any errors or bugs that you found in testing
-* Performance concerns
-* Gaps in documentation
-* Thoughts on how you feel this feature will work in practice
-
-Please provide feedback on the [tracking issue](https://github.com/rust-lang/cargo/issues/8415)
-or create an issue for any bugs encountered.
-
-To get started
-1. Have a (recent) nightly version installed
-2. Place `cargo-features = ["workspace-inheritance"]` at the top of any `Cargo.toml` you 
-plan to use this feature in
-3. Create a `[workspace.package]` and `[workspace.dependencies]` in your workspace `Cargo.toml`
-4. Move any package keys or dependencies you feel should be shared between crates to their 
-respective workspace table
-5. Change any keys you want to inherit to `{key}.workspace = true` in the member `Cargo.toml`
-6. run `cargo +nightly check`
-
-An example port has been made [in this PR](https://github.com/clap-rs/clap/pull/3719) as
-a "real-life" guide.
-
-### The `workspace.package` table
-
-*Stabilization*: This would be in [`workspaces.md`][workspaces], under
-[The `workspace.metadata` table][workspace-metadata-table]
-
-The `workspace.package` table is where you define keys that can be
-inherited by members of a workspace. These keys can be inherited by
-defining them in the member package with `{key}.workspace = true`.
-
-Keys that are supported:
-
-|                |                 |
-|----------------|-----------------|
-| `authors`      | `categories`    |
-| `description`  | `documentation` |
-| `edition`      | `exclude`       |
-| `homepage`     | `include`       |
-| `keywords`     | `license`       |
-| `license-file` | `publish`       |
-| `readme`       | `repository`    |
-| `rust-version` | `version`       |
-
-- `license-file` and `readme` are relative to the workspace root
-- `include` and `exclude` are relative to your package root
-
-Example:
-```toml
-# [PROJECT_DIR]/Cargo.toml
-[workspace]
-members = ["bar"]
-
-[workspace.package]
-version = "1.2.3"
-authors = ["Nice Folks"]
-description = "..."
-documentation = "https://example.github.io/example"
-```
-
-```toml
-# [PROGJCT_DIR]/bar/Cargo.toml
-cargo-features = ["workspace-inheritance"]
-
-[package]
-name = "bar"
-version.workspace = true
-authors.workspace = true
-description.workspace = true
-documentation.workspace = true
-```
-
-
-### The `workspace.dependencies` table
-
-The `workspace.dependencies` table is where you define dependencies to be
-inherited by members of a workspace. 
-
-Specifying a workspace dependency is similar to [package dependencies][specifying-dependencies] except:

-*Stabilization*: This would be in [`specifying-dependencies.md`][specifying-dependencies],
-under [Renaming dependencies in Cargo.toml][renaming-dependencies-in-cargotoml]
-
-Dependencies can be inherited from a workspace by specifying the
-dependency in the workspace's [`[workspace.dependencies]`][workspace.dependencies] table.
-After that add it to the `[dependencies]` table with `dep.workspace = true`.
-
-The `workspace` key can be defined with:
-- [`optional`][optional]: Note that the`[workspace.dependencies]` table is not allowed to specify `optional`.
-- [`features`][features]: These are additive with the features declared in the `[workspace.dependencies]`
-
-The `workspace` key cannot be defined with:
-
-|                  |                    |

-
-Dependencies in the `[dependencies]`, `[dev-dependencies]`, `[build-dependencies]`, and

+### The `workspace.package` table
+
+The `workspace.package` table is where you define keys that can be
+inherited by members of a workspace. These keys can be inherited by
+defining them in the member package with `{key}.workspace = true`.
+
+Keys that are supported:
