+## How to contribute
+
+### Did you find a bug?
+
+* **Ensure the bug was not already reported** by searching on GitHub under [Issues](https://github.com/golangci/golangci-lint-action/issues).
+
+* If you're unable to find an open issue addressing the problem, [open a new one](https://github.com/golangci/golangci-lint-action/issues/new).
+  Be sure to include a **title and clear description**, as much relevant information as possible,
+  and a **code sample** or an **executable test case** demonstrating the expected behavior that is not occurring.
+
+* **Do not open up a GitHub issue if the bug is a security vulnerability**,
+  and instead to refer to our [security policy](https://github.com/golangci/golangci-lint-action?tab=security-ov-file).
+
+### Do you intend to add a new feature or change an existing one?
+
+* Suggest your change inside an [issue](https://github.com/golangci/golangci-lint-action/issues).
+
+* Do not open a pull request on GitHub until you have collected positive feedback about the change.
+
+### Did you write a patch that fixes a bug?
+
+* Open a new GitHub pull request with the patch.
+
+* Ensure the PR description clearly describes the problem and solution.
+  Include the relevant issue number if applicable.
+
+## Development of this action
+
+1. Install [act](https://github.com/nektos/act#installation)
+2. Make a symlink for `act` to work properly: `ln -s . golangci-lint-action`
+3. Install dependencies: `npm install`
+4. Build: `npm run build`
+5. Run `npm run local` after any change to test it
+
+### Releases
+
+```bash
+npm version <major | minor | patch> -m "Upgrade to %s"
+```
+
+- https://docs.npmjs.com/cli/v11/commands/npm-version
+
+The "major tag" (ex: `v6`) should be deleted and then recreated manually.

 [![Build Status](https://github.com/golangci/golangci-lint-action/workflows/build-and-test/badge.svg)](https://github.com/golangci/golangci-lint-action/actions)
 
 It's the official GitHub action for [golangci-lint](https://github.com/golangci/golangci-lint) from its authors.
+
 The action runs [golangci-lint](https://github.com/golangci/golangci-lint) and reports issues from linters.
 
 ![GitHub Annotations](./static/annotations.png)
 
-## Compatibility
+![Logs](./static/colored-line-number.png)
 
-* `v2.0.0+` works with `golangci-lint` version >= `v1.28.3`
-* `v1.2.2` is deprecated due to we forgot to change the minimum version of `golangci-lint` to `v1.28.3` ([issue](https://github.com/golangci/golangci-lint-action/issues/39))
-* `v1.2.1` works with `golangci-lint` version >= `v1.14.0` ([issue](https://github.com/golangci/golangci-lint-action/issues/39))

+You will also likely need to add the following `.gitattributes` file to ensure that line endings for Windows builds are properly formatted:
+
+```.gitattributes
+*.go text eol=lf
+```
+
+</details>
+
+## Compatibility
+
+* `v6.0.0+` removes `annotations` option, removes the default output format (`github-actions`).
+* `v5.0.0+` removes `skip-pkg-cache` and `skip-build-cache` because the cache related to Go itself is already handled by `actions/setup-go`.
+* `v4.0.0+` requires an explicit `actions/setup-go` installation step before using this action: `uses: actions/setup-go@v5`.
+  The `skip-go-installation` option has been removed.
+* `v2.0.0+` works with `golangci-lint` version >= `v1.28.3`
+* `v1.2.2` is deprecated due to we forgot to change the minimum version of `golangci-lint` to `v1.28.3` ([issue](https://github.com/golangci/golangci-lint-action/issues/39))
+* `v1.2.1` works with `golangci-lint` version >= `v1.14.0` ([issue](https://github.com/golangci/golangci-lint-action/issues/39))
+
+## Options
+
+### `version`
+
+(optional)
+
+The version of golangci-lint to use.
+
+When `install-mode` is:
+* `binary` (default): the value can be v1.2 or v1.2.3 or `latest` to use the latest version.
+* `goinstall`: the value can be v1.2.3, `latest`, or the hash of a commit.
+* `none`: the value is ignored.
+
+<details>
+<summary>Example</summary>
+
+```yml
+uses: golangci/golangci-lint-action@v6
+with:
+  version: v1.58
+  # ...
+```
+
+</details>
+
+### `install-mode`
+
+(optional)
+
+The mode to install golangci-lint: it can be `binary`, `goinstall`, or `none`.
+
+The default value is `binary`.
+
+<details>
+<summary>Example</summary>
+
+```yml
+uses: golangci/golangci-lint-action@v6
+with:
+  install-mode: "goinstall"
+  # ...
+```
+
+</details>
+
+### `github-token`
+
+(optional)
+
+When using `only-new-issues` option, the GitHub API is used, so a token is required.
+
+By default, it uses the `github.token` from the action.
+
+<details>
+<summary>Example</summary>
+
+```yml
+uses: golangci/golangci-lint-action@v6
+with:
+  github-token: xxx
+  # ...
+```
+
+</details>
+
+### `only-new-issues`
+
+(optional)
+
+Show only new issues.
+
+The default value is `false`.
+
+* `pull_request` and `pull_request_target`: the action gets the diff of the PR content from the [GitHub API](https://docs.github.com/en/rest/pulls/pulls?apiVersion=2022-11-28#get-a-pull-request) and use it with `--new-from-patch`.
+* `push`: the action gets the diff of the push content (difference between commits before and after the push) from the [GitHub API](https://docs.github.com/en/rest/commits/commits?apiVersion=2022-11-28#compare-two-commits) and use it with `--new-from-patch`.
+* `merge_group`: the action gets the diff by using `--new-from-rev` option (relies on git).
+  You should add the option `fetch-depth: 0` to `actions/checkout` step.
+
+<details>
+<summary>Example</summary>
+
+```yml
+uses: golangci/golangci-lint-action@v6
+with:
+  only-new-issues: true
+  # ...
+```
+
+</details>
+
+### `working-directory`
+
+(optional)
+
+Working directory, useful for monorepos.
+
+<details>
+<summary>Example</summary>
+
+```yml
+uses: golangci/golangci-lint-action@v6
+with:
+  working-directory: somedir
+  # ...
+```
+
+</details>
+
+### `args`
+
+(optional)
+
+golangci-lint command line arguments.
+
+Note: By default, the `.golangci.yml` file should be at the root of the repository.
+The location of the configuration file can be changed by using `--config=`
+
+<details>
+<summary>Example</summary>
+
+```yml
+uses: golangci/golangci-lint-action@v6
+with:
+  args: --timeout=30m --config=/my/path/.golangci.yml --issues-exit-code=0
+  # ...
+```
+
+</details>
+
+### `problem-matchers`
+
+(optional)
+
+Force the usage of the embedded problem matchers.
+
+By default, the [problem matcher of Go (`actions/setup-go`)](https://github.com/actions/setup-go/blob/main/matchers.json) already handles the golangci-lint output (`colored-line-number`).
+
+Works only with `colored-line-number` (the golangci-lint default).
+
+https://golangci-lint.run/usage/configuration/#output-configuration
+
+The default value is `false`.
+
+<details>
+<summary>Example</summary>
+
+```yml
+uses: golangci/golangci-lint-action@v6
+with:
+  problem-matchers: true
+  # ...
+```
+
+</details>
+
+### `skip-cache`
+
+(optional)
+
+If set to `true`, then all caching functionality will be completely disabled,
+takes precedence over all other caching options.
+
+The default value is `false`.
+
+<details>
+<summary>Example</summary>
+
+```yml
+uses: golangci/golangci-lint-action@v6
+with:
+  skip-cache: true
+  # ...
+```
+
+</details>
+
+### `skip-save-cache`
+
+(optional)
+
+If set to `true`, caches will not be saved, but they may still be restored, required `skip-cache: false`.
+
+The default value is `false`.
+
+<details>
+<summary>Example</summary>
+
+```yml
+uses: golangci/golangci-lint-action@v6
+with:
+  skip-save-cache: true
+  # ...
+```
+
+</details>
+
+### `cache-invalidation-interval`
+
+(optional)
+
+Periodically invalidate the cache every `cache-invalidation-interval` days to ensure that outdated data is removed and fresh data is loaded.
+
+The default value is `7`.
+
+If set the number is `<= 0`, the cache will be always invalidate (Not recommended).
+
+<details>
+<summary>Example</summary>
+
+```yml
+uses: golangci/golangci-lint-action@v6
+with:
+  cache-invalidation-interval: 15
+  # ...
+```

+
+## Annotations
+
+Currently, GitHub parses the action's output and creates [annotations](https://github.blog/2018-12-14-introducing-check-runs-and-annotations/).
 
 The restrictions of annotations are the following:
 
-1. Currently, they don't support markdown formatting (see the [feature request](https://github.community/t5/GitHub-API-Development-and/Checks-Ability-to-include-Markdown-in-line-annotations/m-p/56704))
-2. They aren't shown in list of comments like it was with [golangci.com](https://golangci.com). If you would like to have comments - please, up-vote [the issue](https://github.com/golangci/golangci-lint-action/issues/5).
+1. Currently, they don't support Markdown formatting (see the [feature request](https://github.community/t5/GitHub-API-Development-and/Checks-Ability-to-include-Markdown-in-line-annotations/m-p/56704))
+2. They aren't shown in the list of comments.
+   If you would like to have comments - please, up-vote [the issue](https://github.com/golangci/golangci-lint-action/issues/5).
+3. The number of annotations is [limited](https://github.com/actions/toolkit/blob/main/docs/problem-matchers.md#limitations).
+
+To enable annotations, you need to add the `checks` permission to your action.
+
+```yaml annotate
+permissions:
+  # Required: allow read access to the content for analysis.
+  contents: read
+  # Optional: allow read access to pull request. Use with `only-new-issues` option.
+  pull-requests: read
+  # Optional: allow write access to checks to allow the action to annotate code in the PR.
+  checks: write
+```
 
 ## Performance
 
 The action was implemented with performance in mind:
 
-1. We cache data by [@actions/cache](https://github.com/actions/toolkit/tree/master/packages/cache) between builds: Go build cache, Go modules cache, golangci-lint analysis cache.
+1. We cache data from golangci-lint analysis between builds by using [@actions/cache](https://github.com/actions/toolkit/tree/HEAD/packages/cache). 
 2. We don't use Docker because image pulling is slow.
-3. We do as much as we can in parallel, e.g. we download cache, go and golangci-lint binary in parallel.
+3. We do as much as we can in parallel, e.g. we download cache, and golangci-lint binary in parallel.
 
 For example, in a repository of [golangci-lint](https://github.com/golangci/golangci-lint) running this action without the cache takes 50s, but with cache takes 14s:
   * in parallel:
-    * 13s to download Go
     * 4s to restore 50 MB of cache
     * 1s to find and install `golangci-lint`
   * 1s to run `golangci-lint` (it takes 35s without cache)
 
 ## Internals

+Inside our action, we perform 3 steps:
 
 1. Setup environment running in parallel:
-  * restore [cache](https://github.com/actions/cache) of previous analyzes
-  * fetch [action config](https://github.com/golangci/golangci-lint/blob/master/assets/github-action-config.json) and find the latest `golangci-lint` patch version
-    for needed version (users of this action can specify only minor version of `golangci-lint`). After that install [golangci-lint](https://github.com/golangci/golangci-lint) using [@actions/tool-cache](https://github.com/actions/toolkit/tree/master/packages/tool-cache)
-  * install the latest Go 1.x version using [@actions/setup-go](https://github.com/actions/setup-go)
+   * restore [cache](https://github.com/actions/cache) of previous analyses
+   * fetch [action config](https://github.com/golangci/golangci-lint/blob/HEAD/assets/github-action-config.json) and find the latest `golangci-lint` patch version for needed version

+     After that install [golangci-lint](https://github.com/golangci/golangci-lint) using [@actions/tool-cache](https://github.com/actions/toolkit/tree/HEAD/packages/tool-cache)
 2. Run `golangci-lint` with specified by user `args`
 3. Save cache for later builds
 
 ### Caching internals
 
-1. We save and restore the following directories: `~/.cache/golangci-lint`, `~/.cache/go-build`, `~/go/pkg`.
-2. The primary caching key looks like `golangci-lint.cache-{platform-arch}-{interval_number}-{go.mod_hash}`. Interval number ensures that we periodically invalidate
-   our cache (every 7 days). `go.mod` hash ensures that we invalidate the cache early - as soon as dependencies have changed.
-3. We use [restore keys](https://help.github.com/en/actions/configuring-and-managing-workflows/caching-dependencies-to-speed-up-workflows#matching-a-cache-key): `golangci-lint.cache-{interval_number}-`, `golangci-lint.cache-`. GitHub matches keys by prefix if we have no exact match for the primary cache.

 This scheme is basic and needs improvements. Pull requests and ideas are welcome.

-## Development of this action
-
-1. Install [act](https://github.com/nektos/act#installation)
-2. Make a symlink for `act` to work properly: `ln -s . golangci-lint-action`
-3. Prepare deps once: `npm run prepare-deps`
-4. Run `npm run local` after any change to test it
