 This action sets up a go environment for use in actions by:
 
-- Optionally downloading and caching a version of Go by version and adding to `PATH`.
-- Registering problem matchers for error output.
+- optionally downloading and caching a version of Go by version and adding to PATH
+- registering problem matchers for error output
 
-# V5
+# V2
 
-The V5 edition of the action offers:
-
-- Upgraded Node.js runtime from node16 to node20
-
-See full release notes on the [releases page](https://github.com/actions/setup-go/releases).
-
-# V4
-
-The V4 edition of the action offers:
-
- - Enabled caching by default
-
-The action will try to enable caching unless the `cache` input is explicitly set to false.
-
-Please see "[Caching dependency files and build outputs](https://github.com/actions/setup-go#caching-dependency-files-and-build-outputs)" for more information.
-
-# V3
-
-The V3 edition of the action offers:
-
-- Adds `GOBIN` to the `PATH`
-- Proxy support
-- Check latest version
-- Caching packages dependencies
-- stable and oldstable aliases
+The V2 offers:
+- Adds GOBIN to the PATH
+- Proxy Support
+- stable input 
 - Bug Fixes (including issues around version matching and semver)
 
-The action will first check the local cache for a version match. If a version is not found locally, it will pull it from
-the `main` branch of the [go-versions](https://github.com/actions/go-versions/blob/main/versions-manifest.json)
-repository. On miss or failure, it will fall back to downloading directly
-from [go dist](https://storage.googleapis.com/golang). To change the default behavior, please use
-the [check-latest input](#check-latest-version).
-
-**Note:** The `setup-go` action uses executable binaries which are built by Golang side. The action does not build
-golang from source code.
-
-Matching by [semver spec](https://github.com/npm/node-semver):

+Matching by semver spec:
 ```yaml
 steps:
-  - uses: actions/checkout@v4
-  - uses: actions/setup-go@v5
+- uses: actions/checkout@v2
+- uses: actions/setup-go@v2
   with:
     go-version: '^1.13.1' # The Go version to download (if necessary) and use.
-  - run: go version
+- run: go version
 ```
 
-```yaml
-steps:

-  - uses: actions/setup-go@v5
-    with:
-      go-version: '>=1.17.0'
-  - run: go version
-```
-
-> **Note**: Due to the peculiarities of YAML parsing, it is recommended to wrap the version in single quotation marks:
->
-> ```yaml
->   go-version: '1.20'
-> ```
->
-> The recommendation is based on the YAML parser's behavior, which interprets non-wrapped values as numbers and, in the case of version 1.20, trims it down to 1.2, which may not be very obvious.

-

+    stable: 'false'
+    go-version: '1.14.0-rc1' # The Go version to download (if necessary) and use.
+- run: go version
 ```
 
 # Usage
 
 See [action.yml](action.yml)
 
-## Basic
-
+Basic:
 ```yaml
 steps:
-  - uses: actions/checkout@v4
-  - uses: actions/setup-go@v5
+- uses: actions/checkout@master
+- uses: actions/setup-go@v1
   with:
-      go-version: '1.16.1' # The Go version to download (if necessary) and use.
-  - run: go run hello.go
+    go-version: '1.9.3' # The Go version to download (if necessary) and use.
+- run: go run hello.go
 ```
 
-## Check latest version
-
-The `check-latest` flag defaults to `false`. Use the default or set `check-latest` to `false` if you prefer stability
-and if you want to ensure a specific Go version is always used.
-
-If `check-latest` is set to `true`, the action first checks if the cached version is the latest one. If the locally
-cached version is not the most up-to-date, a Go version will then be downloaded. Set `check-latest` to `true` if you
-want the most up-to-date Go version to always be used.
-
-> Setting `check-latest` to `true` has performance implications as downloading Go versions is slower than using cached
-> versions.
-
-```yaml
-steps:
-  - uses: actions/checkout@v4
-  - uses: actions/setup-go@v5
-    with:
-      go-version: '1.14'
-      check-latest: true
-  - run: go run hello.go
-```
-
-## Using stable/oldstable aliases
-
-If `stable` is provided, action will get the latest stable version from
-the [`go-versions`](https://github.com/actions/go-versions/blob/main/versions-manifest.json) repository manifest.
-
-If `oldstable` is provided, when current release is 1.19.x, action will resolve version as 1.18.x, where x is the latest
-patch release.
-
-**Note:** using these aliases will result in same version as using corresponding minor release with `check-latest` input
-set to `true`
-
-```yaml
-steps:
-  - uses: actions/checkout@v4
-  - uses: actions/setup-go@v5
-    with:
-      go-version: 'stable'
-  - run: go run hello.go
-```
-
-```yaml
-steps:
-  - uses: actions/checkout@v4
-  - uses: actions/setup-go@v5
-    with:
-      go-version: 'oldstable'
-  - run: go run hello.go
-```
-
-## Caching dependency files and build outputs:
-
-The action has a built-in functionality for caching and restoring go modules and build outputs. It
-uses [toolkit/cache](https://github.com/actions/toolkit/tree/main/packages/cache) under the hood but requires less configuration settings.
-The `cache` input is optional, and caching is turned on by default.
-
-The action defaults to search for the dependency file - go.sum in the repository root, and uses its hash as a part of
-the cache key. Use `cache-dependency-path` input for cases when multiple dependency files are used, or they are located
-in different subdirectories. The input supports glob patterns.
-
-If some problem that prevents success caching happens then the action issues the warning in the log and continues the execution of the pipeline.
-
-**Caching in monorepos**
-
-```yaml
-steps:
-  - uses: actions/checkout@v4
-  - uses: actions/setup-go@v5
-    with:
-      go-version: '1.17'
-      check-latest: true
-      cache-dependency-path: |
-             subdir/go.sum
-             tools/go.sum
-    # cache-dependency-path: "**/*.sum"
-
-  - run: go run hello.go
-  ```
-
-## Getting go version from the go.mod file
-
-The `go-version-file` input accepts a path to a `go.mod` file or a `go.work` file that contains the version of Go to be used by a project.
-
-The `go` directive in `go.mod` can specify a patch version or omit it altogether (e.g., `go 1.22.0` or `go 1.22`).  
-If a patch version is specified, that specific patch version will be used.  
-If no patch version is specified, it will search for the latest available patch version in the cache,
-[versions-manifest.json](https://github.com/actions/go-versions/blob/main/versions-manifest.json), and the
-[official Go language website](https://golang.org/dl/?mode=json&include=all), in that order.
-
-If both the `go-version` and the `go-version-file` inputs are provided then the `go-version` input is used.
-> The action will search for the `go.mod` file relative to the repository root
-
-```yaml
-steps:
-  - uses: actions/checkout@v4
-  - uses: actions/setup-go@v5
-    with:
-      go-version-file: 'path/to/go.mod'
-  - run: go version
-```
-
-## Matrix testing
-
+Matrix Testing:
 ```yaml
 jobs:
   build:
-    runs-on: ubuntu-latest
+    runs-on: ubuntu-16.04
     strategy:
       matrix:
         go: [ '1.14', '1.13' ]
     name: Go ${{ matrix.go }} sample
     steps:
-      - uses: actions/checkout@v4
+      - uses: actions/checkout@v2
       - name: Setup go
-        uses: actions/setup-go@v5
+        uses: actions/setup-go@v1
         with:
           go-version: ${{ matrix.go }}
       - run: go run hello.go
 ```
 
-### Supported version syntax
-
-The `go-version` input supports the following syntax:
-
-- Specific versions: `1.15`, `1.16.1`, `1.17.0-rc.2`, `1.16.0-beta.1`
-- SemVer's version range syntax: `^1.13.1`, `>=1.18.0-rc.1`
-
-For more information about semantic versioning, please refer to [semver](https://github.com/npm/node-semver)
-documentation.
-
-## Using `setup-go` on GHES
-
-`setup-go` comes pre-installed on the appliance with GHES if Actions is enabled.
-When dynamically downloading Go distributions, `setup-go` downloads distributions from [`actions/go-versions`](https://github.com/actions/go-versions) on github.com (outside of the appliance).
-
-These calls to `actions/go-versions` are made via unauthenticated requests, which are limited to [60 requests per hour per IP](https://docs.github.com/en/rest/overview/resources-in-the-rest-api#rate-limiting).
-If more requests are made within the time frame, then the action leverages the `raw API` to retrieve the version-manifest. This approach does not impose a rate limit and hence facilitates unrestricted consumption. This is particularly beneficial for GHES runners, which often share the same IP, to avoid the quick exhaustion of the unauthenticated rate limit.
-If that fails as well the action will try to download versions directly from https://storage.googleapis.com/golang.
-
-If that fails as well you can get a higher rate limit with [generating a personal access token on github.com](https://github.com/settings/tokens/new) and passing it as the `token` input to the action:
-
-```yaml
-uses: actions/setup-go@v5
-with:
-  token: ${{ secrets.GH_DOTCOM_TOKEN }}
-  go-version: '1.18'
-```
-
-If the runner is not able to access github.com, any Go versions requested during a workflow run must come from the runner's tool cache.
-See "[Setting up the tool cache on self-hosted runners without internet access](https://docs.github.com/en/enterprise-server@3.2/admin/github-actions/managing-access-to-actions-from-githubcom/setting-up-the-tool-cache-on-self-hosted-runners-without-internet-access)"
-for more information.
-
-## Recommended permissions
-
-When using the `setup-go` action in your GitHub Actions workflow, it is recommended to set the following permissions to ensure proper functionality:
-
-```yaml
-permissions:
-  contents: read # access to check out code and install dependencies
-```
-

-# 0. Caching dependencies
-Date: 2022-04-13
-
-Status: Accepted
-
-# Context
-`actions/setup-go` is the one of the most popular action related to Golang in GitHub Actions. Many customers use it in conjunction with [actions/cache](https://github.com/actions/cache) to speed up dependency installation process.
-See more examples on proper usage in [actions/cache documentation](https://github.com/actions/cache/blob/main/examples.md#go---modules).
-
-# Goals & Anti-Goals
-Integration of caching functionality into `actions/setup-go` action will bring the following benefits for action users:
-- Decrease the entry threshold for using the cache for Go dependencies and simplify initial configuration
-- Simplify YAML pipelines because there will be no need for additional steps to enable caching
-- More users will use cache for Go so more customers will have fast builds!
-
-We don't pursue the goal to provide wide customization of caching in scope of `actions/setup-go` action. The purpose of this integration is covering ~90% of basic use-cases. If user needs flexible customization, we should advice them to use `actions/cache` directly.
-
-# Decision
-- Add `cache` input parameter to `actions/setup-go`. For now, input will accept the following values:
-  - `true` - enable caching for go dependencies
-  - `false`- disable caching for go dependencies. This value will be set as default value
-- Cache feature will be disabled by default to make sure that we don't break existing customers. We will consider enabling cache by default in next major releases
-- Action will try to search a go.sum files in the repository and throw error in the scenario that it was not found
-- The hash of found file will be used as cache key (the same approach like [actions/cache](https://github.com/actions/cache/blob/main/examples.md#go---modules) recommends)
-- The following key cache will be used `${{ runner.os }}-go${{ go-version }}-${{ hashFiles('<go.sum-path>') }}`
-- Action will cache global cache from the `go env GOMODCACHE` and `go env GOCACHE` commands.
-- Add a `cache-dependency-path` input parameter to `actions/setup-go`. The new input will accept an array or regex of dependency files. The field will accept a path (relative to the repository root) to dependency files. If the provided path contains wildcards, the action will search all matching files and calculate a common hash like the ${{ hashFiles('**/go.sum') }} YAML construction does.
-
-# Example of real use-cases
-
- - With cache
-
-```yml
-steps:
-- uses: actions/checkout@v4
-- uses: actions/setup-go@v3
-  with:
-    go-version: '18'
-    cache: true
-```
-
- - With cache-dependency-path
-
- ```yml
-steps:
-- uses: actions/checkout@v4
-- uses: actions/setup-go@v3
-  with:
-    go-version: '18'
-    cache: true
-    cache-dependency-path: **/go.sum
-```
-
- ```yml
-steps:
-- uses: actions/checkout@v4
-- uses: actions/setup-go@v3
-  with:
-    go-version: '18'
-    cache: true
-    cache-dependency-path: |
-        **/go.sum
-        **/go.mod
-```
-
-# Release process
-
-As soon as functionality is implemented, we will release minor update of action. No need to bump major version since there are no breaking changes for existing users.
-After that, we will update [starter-workflows](https://github.com/actions/starter-workflows/blob/main/ci/go.yml)

-## Contribute documentation
-
-Documentation is a super important, critical part of this project. Docs are how we keep track of what we're doing, how, and why. It's how we stay on the same page about our policies and how we tell others everything they need to be able to use this project or contribute to it. 
-
-Documentation contributions of any size are welcome! Feel free to contribute even if you're just rewording a sentence to be more clear, or fixing a spelling mistake!
-
-**How to contribute:**
-
-Pull requests are the easiest way to contribute changes to git repos at GitHub. They are the preferred contribution method, as they offer a nice way of commenting and amending the proposed changes.
-
-- Please check that no one else has already created a pull request with these changes
-- Use a "feature branch" for your changes. That separates the changes in the pull request from your other changes and makes it easy to edit/amend commits in the pull request 
-- Make sure your changes are formatted correctly and consistently with the rest of the documentation
-- Re-read what you wrote, and run a spellchecker on it to make sure you didn't miss anything
-- If your pull request is connected to an open issue, please, leave a link to this issue in the `Related issue:` section
-- If you later need to add new commits to the pull request, you can simply commit the changes to the local branch and then push them. The pull request gets automatically updated
-
-**Once you've filed the pull request:**
-
-- Maintainers will review your pull request
-- If a maintainer requests changes, first of all, try to think about this request critically and only after that implement and request another review
-- If your PR gets accepted, it will soon be merged into the main branch. But your contribution will take effect only after the release of a new version of the action
-> Sometimes maintainers reject pull requests and that's ok! Usually, along with rejection, we supply the reason for it. Nonetheless, we still really appreciate you taking the time to do it, and we don't take that lightly :heart:
-
-## Contribute code
-
-We like code commits a lot! They're super handy, and they keep the project going and doing the work it needs to do to be useful to others.
-
-Code contributions of just about any size are acceptable!
-
-The main difference between code contributions and documentation contributions is that contributing code requires the inclusion of relevant tests for the code being added or changed. Contributions without accompanying tests will be held off until a test is added unless the maintainers consider the specific tests to be either impossible or way too much of a burden for such a contribution.
-
-**How to contribute:**
-
-Pull requests are the easiest way to contribute changes to git repos at GitHub. They are the preferred contribution method, as they offer a nice way of commenting and amending the proposed changes.
-
-- Please check that no one else has already created a pull request with these changes
-- Use a "feature branch" for your changes. That separates the changes in the pull request from your other changes and makes it easy to edit/amend commits in the pull request
--  **Run `pre-checkin` script to format, lint, build and test changes**
-- Make sure your changes are well formatted and that all tests are passing
-- If your pull request is connected to an open issue, please, leave a link to this issue in the `Related issue:` section
-- If you later need to add new commits to the pull request, you can simply commit the changes to the local branch and then push them. The pull request gets automatically updated
-
-**Learn more about how to work with the repository:**
-
-- To implement new features or fix bugs, you need to make changes to the `.ts` files, which are located in the `src` folder
-- To comply with the code style, **you need to run the `format` script**
-- To lint the code, **you need to run the `lint:fix` script**
-- To transpile source code to `javascript` we use [NCC](https://github.com/vercel/ncc). **It is very important to run the `build` script after making changes**, otherwise your changes will not get into the final `javascript` build
-- You can also start formatting, building code, and testing with a single `pre-checkin` command
-
-**Learn more about how to implement tests:**
-
-Adding or changing tests is an integral part of making a change to the code. 
-Unit tests are in the `__tests__` folder, and end-to-end tests are in the `workflows` folder (in particular, in the file [versions.yml](https://github.com/actions/setup-go/blob/main/.github/workflows/versions.yml)).
-
-- The contributor can add various types of tests (like unit tests or end-to-end tests), which, in his opinion, will be necessary and sufficient for testing new or changed functionality
-- Tests should cover a successful execution, as well as some edge cases and possible errors
-- As already mentioned, pull requests without tests will be considered more carefully by maintainers. If you are sure that in this situation the tests are not needed or cannot be implemented with a commensurate effort - please add this clarification message to your pull request
-
-**Once you've filed the pull request:**
-
-- CI will start automatically with some checks. Wait until the end of the execution and make sure that all checks passed successfully. If some checks fail, you can open them one by one, try to find the reason for failing and make changes to your code to resolve the problem
-- Maintainers will review your pull request
-- If a maintainer requests changes, first of all, try to think about his request critically and only after that implement and request another review
-- If your PR gets accepted, it will soon be merged into the main branch. But your contribution will take effect only after the release of a new version of the action
-> Sometimes maintainers reject pull requests and that's ok! Usually, along with rejection, we supply the reason for it. Nonetheless, we still really appreciate you taking the time to do it, and we don't take that lightly :heart:

-## Provide support on issues
-
-Helping out other users with their questions is an awesome way of contributing to any community. It's not uncommon for most of the issues on open source projects to be support-related questions by users trying to understand something they ran into or find their way around a known bug.
-
-**To help other folks out with their questions:**
-
-- Go to the [issue tracker](https://github.com/actions/setup-go/issues)
-- Read through the list until you find something that you're familiar enough with to answer to
-- Respond to the issue with whatever details are needed to clarify the question, or get more details about what's going on
-- Once the discussion wraps up and things are clarified, ask the original issue filer (or a maintainer) to close it for you
- 
-*Some notes on picking up support issues:*
-
-- Avoid responding to issues you don't know you can answer accurately
-- Try to refer to past issues with accepted answers as much as possible. Link to them from your replies
-- Be kind and patient with users. Often, folks who have run into confusing things might be upset or impatient. This is natural. If you feel uncomfortable in conversation with them, it's better to stay away or withdraw from the issue.

-
-## Review pull requests
- 
-
-Another great way to contribute is pull request reviews. Please, be extra kind: people who submit code/doc contributions are putting themselves in a pretty vulnerable position, and have put time and care into what they've done (even if that's not obvious to you!) Please, always respond with respect, and be understanding, but don't feel like you need to sacrifice your standards for their sake, either.
- 
-**How to review:**
-
-- Go to the [pull requests](https://github.com/actions/setup-go/pulls)
-- Make sure you're familiar with the code or documentation is updated, unless it's a minor change (spellchecking, minor formatting, etc.)
-- Review changes using the GitHub functionality. You can ask a clarifying question, point out an error or suggest an alternative. 
-> Note: You may ask for minor changes - "nitpicks", but consider whether they are real blockers to merging or not
-- Submit your review, which may include comments, an approval, or a changes request
