 ## 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.

-## Caching dependency files and build outputs:

-The action has a built-in functionality for caching and restoring go modules and build outputs. It uses [actions/cache](https://github.com/actions/cache) under the hood but requires less configuration settings. The `cache` input is optional, and caching is turned off by default.
+## Using stable/oldstable aliases

-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.
+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

 ## 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 you will start to see rate-limit errors during downloading that looks like: `##[error]API rate limit exceeded for...`. After that error the action will try to download versions directly from https://storage.googleapis.com/golang, but it also can have rate limit so it's better to put token.

 - Please check that no one else has already created a pull request with these changes

+-  **Run `pre-checkin` script to format, lint, build and test changes**
 - Make sure your changes are well formatted and that all tests are passing

 - 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
