 [![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
 
-* `v4.0.0+` requires an explicit setup-go installation step before using this action: `uses: actions/setup-go@v5`.
+* `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))

-## Comments and Annotations
+## Options
+
+### `version`
+
+(required)
+
+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.
+* When `install-mode` is `goinstall` the value can be v1.2.3, `latest`, or the hash of a commit.
+
+```yml
+uses: golangci/golangci-lint-action@v5
+with:
+  version: latest
+  # ...
+```
+
+### `install-mode`
+
+(optional)
+
+The mode to install golangci-lint: it can be `binary` or `goinstall`.
+
+The default value is `binary`.
+
+```yml
+uses: golangci/golangci-lint-action@v5
+with:
+  install-mode: "goinstall"
+  # ...
+```
+
+### `only-new-issues`
+
+(optional)
+
+Show only new issues.
+
+The default value is `false`.
+
+```yml
+uses: golangci/golangci-lint-action@v5
+with:
+  only-new-issues: true
+  # ...
+```
+
+* `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.
+
+### `working-directory`
+
+(optional)
+
+Working directory, useful for monorepos.
+
+```yml
+uses: golangci/golangci-lint-action@v5
+with:
+  working-directory: somedir
+  # ...
+```
+
+### `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`.
+
+```yml
+uses: golangci/golangci-lint-action@v5
+with:
+  skip-cache: true
+  # ...
+```
+
+### `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`.
+
+```yml
+uses: golangci/golangci-lint-action@v5
+with:
+  skip-save-cache: true
+  # ...
+```
+
+### `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`.
+
+```yml
+uses: golangci/golangci-lint-action@v5
+with:
+  cache-invalidation-interval: 15
+  # ...
+```
+
+If set the number is `<= 0`, the cache will be always invalidate (Not recommended).
+
+### `annotations`
+
+(optional)
+
+To enable/disable GitHub Action annotations.
+
+If disabled (`false`), the output format(s) will follow the golangci-lint configuration file (or CLI flags from `args`) 
+and use the same default as golangci-lint (i.e. `colored-line-number`).
+
+https://golangci-lint.run/usage/configuration/#output-configuration
+
+The default value is `true`.
+
+```yml
+uses: golangci/golangci-lint-action@v5
+with:
+  annotations: false
+  # ...
+```
+
+### `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=`
+
+```yml
+uses: golangci/golangci-lint-action@v5
+with:
+  args: --timeout=30m --config=/my/path/.golangci.yml --issues-exit-code=0

 The restrictions of annotations are the following:
