 [![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
 
-* `v3.0.0+` requires explicit setup-go installation step prior to using this action: `uses: actions/setup-go@v3`.
+* `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))

+## 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).

+   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

-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.

 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.
