+## Ignoring dependencies at specific versions
+
+Ignore a dependency at specific versions by appending `@<version>` to the end of the dependency's name in an `ignore` list.  If a dependency is configured to be ignored at a specific version, licensed will not ignore non-matching versions of the dependency.
+
+The version value can be one of:
+
+1. `"*"` - match any version value
+1. any version string, or version range string, that can be parsed by `Gem::Requirement`
+   - a semantic version - `dependency@1.2.3`
+   - a gem requirement range - `dependency@~> 1.0.0` or `dependency@< 3.0`
+   - see the [Rubygems version guides](https://guides.rubygems.org/patterns/#pessimistic-version-constraint) for more details about specifying gem version requirements
+1. a value that can't be parsed by `Gem::Requirement`, which will only match dependencies with the same version string

 The npm source will detect dependencies when `pnpm-lock.yaml` is found at an apps `source_path`.  It uses `pnpm licenses list` to enumerate dependencies and metadata.
 
+All dependencies enumerated by the pnpm source include the dependency version in the dependency's name identifier.  All [reviewed](../configuration/reviewing_dependencies.md) or [ignored](../configuration/ignoring_dependencies.md) dependencies must include a version signifier in the configured dependency name.
+
 **NOTE** [pnpm licenses list](https://pnpm.io/cli/licenses) is an experimental CLI command and subject to change.  If changes to pnpm result in unexpected or broken behavior in licensed please open an [issue](https://github.com/github/licensed/issues/new).
