-          Object form, made available under the License, as indicated by a
-          copyright notice that is included in or attached to the work

-
-          "Derivative Works" shall mean any work, whether in Source or Object
-          form, that is based on (or derived from) the Work and for which the
-          editorial revisions, annotations, elaborations, or other modifications
-          represent, as a whole, an original work of authorship. For the purposes
-          of this License, Derivative Works shall not include works that remain

-
-          "Contribution" shall mean any work of authorship, including

-          use, offer to sell, sell, import, and otherwise transfer the Work,
-          where such license applies only to those patent claims licensable
-          by such Contributor that are necessarily infringed by their

-          with the Work to which such Contribution(s) was submitted. If You
-          institute patent litigation against any entity (including a
-          cross-claim or counterclaim in a lawsuit) alleging that the Work
-          or a Contribution incorporated within the Work constitutes direct
-          or contributory patent infringement, then any patent licenses
-          granted to You under this License for that Work shall terminate
-          as of the date such litigation is filed.
-
-       4. Redistribution. You may reproduce and distribute copies of the

-              that You distribute, all copyright, patent, trademark, and
-              attribution notices from the Source form of the Work,
-              excluding those notices that do not pertain to any part of
-              the Derivative Works; and

-              within a display generated by the Derivative Works, if and
-              wherever such third-party notices normally appear. The contents
-              of the NOTICE file are for informational purposes only and

-              as modifying the License.
-
-          You may add Your own copyright statement to Your modifications and
-          may provide additional or different license terms and conditions
-          for use, reproduction, or distribution of Your modifications, or

-          reproduction, and distribution of the Work otherwise complies with
-          the conditions stated in this License.
-
-       5. Submission of Contributions. Unless You explicitly state otherwise,

-          by You to the Licensor shall be under the terms and conditions of

-          incidental, or consequential damages of any character arising as a
-          result of this License or out of the use or inability to use the
-          Work (including but not limited to damages for loss of goodwill,
-          work stoppage, computer failure or malfunction, or any and all
-          other commercial damages or losses), even if such Contributor
-          has been advised of the possibility of such damages.
-
-       9. Accepting Warranty or Additional Liability. While redistributing
-          the Work or Derivative Works thereof, You may choose to offer,
-          and charge a fee for, acceptance of support, warranty, indemnity,
-          or other liability obligations and/or rights consistent with this

-          on Your own behalf and on Your sole responsibility, not on behalf
-          of any other Contributor, and only if You agree to indemnify,
-          defend, and hold each Contributor harmless for any liability
-          incurred by, or claims asserted against, such Contributor by reason
-          of your accepting any such warranty or additional liability.

-       APPENDIX: How to apply the Apache License to your work.
-
-          To apply the Apache License to your work, attach the following
-          boilerplate notice, with the fields enclosed by brackets "[]"

-          the brackets!)  The text should be enclosed in the appropriate
-          comment syntax for the file format. We also recommend that a
-          file or class name and description of purpose be included on the
-          same "printed page" as the copyright notice for easier
-          identification within third-party archives.

+The action has a built-in functionality for caching and restoring dependencies. It uses [actions/cache](https://github.com/actions/cache) under the hood for caching dependencies but requires less configuration settings. Supported package managers are `npm`, `yarn`, `pnpm` (v6.10+). The `cache` input is optional, and caching is turned off by default.
+
+The action defaults to search for the dependency file (`package-lock.json` or `yarn.lock`) in the repository root, and uses its hash as a part of the cache key. Use `cache-dependency-path` for cases when multiple dependency files are used, or they are located in different subdirectories.
+
+See the examples of using cache for `yarn` / `pnpm` and  `cache-dependency-path` input in the [Advanced usage](docs/advanced-usage.md#caching-packages-dependencies) guide.

+# 0. Support caching dependencies for mono repos
+Date: 2021-07-13
+
+Status: Proposed
+
+## Context
+Currently, `actions/setup-node` supports caching dependencies for Npm and Yarn package managers.  
+For the first iteration, we have decided to not support cases where `package-lock.json` / `yarn.lock` are located outside of repository root.  
+Current implementation searches the following file patterns in the repository root: `package-lock.json`, `yarn.lock` (in order of resolving priorities)
+
+Obviously, it made build-in caching unusable for mono-repos and repos with complex structure.  
+We would like to revisit this decision and add customization for dependencies lock file location.
+
+## Proposal
+We have the following options:
+1. Allow to specify  directory where `package-lock.json` or `yarn.lock` are located
+2. Allow to specify path to the dependencies lock file (including directory path and filename)
+
+The second option looks more generic because it allows to:
+- specify multiple dependencies files using file patterns like `**/package-lock.json` ([one of recommended approaches in actions/cache](https://github.com/actions/cache/blob/main/examples.md#macos-and-ubuntu))
+- specify custom dependencies files like `src/npm-shrinkwrap.json`
+- change default resolving priority if both `yarn.lock` and `package-lock.json` exist in repository
+
+## Decision
+
+Add `cache-dependency-path` input that will accept path (relative to repository root) to dependencies lock file.  
+If provided path contains wildcards, the action will search all maching files and calculate common hash like `${{ hashFiles('**/package-lock.json') }}` YAML construction does.  
+The hash of provided matched files will be used as a part of cache key.
+
+Yaml examples:
+```yml
+steps:
+- uses: actions/checkout@v2
+- uses: actions/setup-node@v2
+  with:
+    node-version: 14
+    cache: npm
+    cache-dependency-path: 'sub-project/package-lock.json'
+```
+```yml

+- uses: actions/checkout@v2
+- uses: actions/setup-node@v2
+  with:
+    node-version: 14
+    cache: yarn
+    cache-dependency-path: 'sub-project/**/yarn.lock'
+```

 # Advanced usage
 
-### Check latest version:
+## Check latest version
 
 The `check-latest` flag defaults to `false`. When set to `false`, the action will first check the local cache for a semver match. If unable to find a specific version in the cache, the action will attempt to download a version of Node.js. It will pull LTS versions from [node-versions releases](https://github.com/actions/node-versions/releases) and on miss or failure will fall back to the previous behavior of downloading directly from [node dist](https://nodejs.org/dist/). Use the default or set `check-latest` to `false` if you prefer stability and if you want to ensure a specific version of Node.js is always used.
