+## 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.

-## Compatibility
+![Logs](./static/colored-line-number.png)
 
-* `v3.0.0+` requires explicit setup-go installation step prior to using this action: `uses: actions/setup-go@v3`.
-  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))

+
+## Compatibility
+
+* `v8.0.0` works with `golangci-lint` version >= `v2.1.0`
+* `v7.0.0` supports golangci-lint v2 only.
+* `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 because 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 v2.3, v2.3.4, or `latest` to use the latest version.
+* `goinstall`: the value can be v2.3.4, `latest`, or the hash of a commit.
+* `none`: the value is ignored.
+
+<details>
+<summary>Example</summary>
+
+```yml
+uses: golangci/golangci-lint-action@v8
+with:
+  version: v2.1
+  # ...
+```
+
+</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@v8
+with:
+  install-mode: "goinstall"
+  # ...
+```
+
+</details>
+
+### `github-token`
+
+(optional)
+
+When using the `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@v8
+with:
+  github-token: xxx
+  # ...
+```
+
+</details>
+
+### `verify`
+
+(optional)
+
+This option is `true` by default.
+
+If the GitHub Action detects a configuration file, validation will be performed unless this option is set to `false`.
+If there is no configuration file, validation is skipped.
+
+The JSON Schema used to validate the configuration depends on the version of golangci-lint you are using.
+
+<details>
+<summary>Example</summary>
+
+```yml
+uses: golangci/golangci-lint-action@v8
+with:
+  verify: false
+  # ...
+```
+
+</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 uses it with `--new-from-patch`.
+* `push`: the action gets the diff of the push content (the 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 uses it with `--new-from-patch`.
+* `merge_group`: the action gets the diff by using the `--new-from-rev` option (relies on git).
+  You should add the option `fetch-depth: 0` to the `actions/checkout` step.
+
+<details>
+<summary>Example</summary>
+
+```yml
+uses: golangci/golangci-lint-action@v8
+with:
+  only-new-issues: true
+  # ...
+```
+
+</details>
+
+### `working-directory`
+
+(optional)
+
+The golangci-lint working directory, useful for monorepos. The default is the project root.
+
+<details>
+<summary>Example</summary>
+
+```yml
+uses: golangci/golangci-lint-action@v8
+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=`.
+
+> [!IMPORTANT]
+> Adding a `=` between the flag name and its value is important because the action parses the arguments on spaces.
+
+<details>
+<summary>Example</summary>
+
+```yml
+uses: golangci/golangci-lint-action@v8
+with:
+  # In some rare cases,
+  # you may need to use `${{ github.workspace }}` as the base directory to reference your configuration file.
+  args: --config=/my/path/.golangci.yml --issues-exit-code=0
+  # ...
+```
+
+</details>
+
+### `problem-matchers`
+
+(optional)
+
+Forces 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 default golangci-lint output (`text`).
+
+Works only with the `text` format (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@v8
+with:
+  problem-matchers: true
+  # ...
+```
+
+</details>
+
+### `skip-cache`
+
+(optional)
+
+If set to `true`, all caching functionality will be completely disabled.
+This takes precedence over all other caching options.
+
+The default value is `false`.
+
+<details>
+<summary>Example</summary>
+
+```yml
+uses: golangci/golangci-lint-action@v8
+with:
+  skip-cache: true
+  # ...
+```
+
+</details>
+
+### `skip-save-cache`
+
+(optional)
+
+If set to `true`, caches will not be saved, but they may still be restored, requiring `skip-cache: false`.
+
+The default value is `false`.
+
+<details>
+<summary>Example</summary>
+
+```yml
+uses: golangci/golangci-lint-action@v8
+with:
+  skip-save-cache: true
+  # ...
+```
+
+</details>
+
+### `cache-invalidation-interval`
+
+(optional)
+
+Periodically invalidate a cache every `cache-invalidation-interval` days to ensure that outdated data is removed and fresh data is loaded.
+
+The default value is `7`.
+
+If the number is `<= 0`, the cache will always be invalidated (not recommended).
+
+<details>
+<summary>Example</summary>
+
+```yml
+uses: golangci/golangci-lint-action@v8
+with:
+  cache-invalidation-interval: 15
+  # ...
+```
+
+</details>
+
+## 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 as follows:
+
+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).
+
+Permissions required:
+
+```yaml annotate
+permissions:
+  # Required: allow read access to the content for analysis.
+  contents: read
+  # Optional: allow read access to pull requests. Use with `only-new-issues` option.
+  pull-requests: read
+```
+
+For annotations to work, use the default format output (`text`) and either use `actions/setup-go` in the job or enable the internal [problem matchers](#problem-matchers).
 
 ## 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.

 ### 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.

-## 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
