 ## Actions (`actions`)

 - `ENABLED`: **false**: Enable/Disable actions capabilities
- `DEFAULT_ACTIONS_URL`: **github**: Default platform to get action plugins, `github` for `https://github.com`, `self` for the current Gitea instance.
+- `DEFAULT_ACTIONS_URL`: **https://gitea.com**: Default address to get action plugins, e.g. the default value means downloading from "<https://gitea.com/actions/checkout>" for "uses: actions/checkout@v3"
 - `STORAGE_TYPE`: **local**: Storage type for actions logs, `local` for local disk or `minio` for s3 compatible object storage service, default is `local` or other name defined with `[storage.xxx]`
 - `MINIO_BASE_PATH`: **actions_log/**: Minio base path on the bucket only available when STORAGE_TYPE is `minio`

-`DEFAULT_ACTIONS_URL` indicates where the Gitea Actions runners should find the actions with relative path.
-For example, `uses: actions/checkout@v3` means `https://github.com/actions/checkout@v3` since the value of `DEFAULT_ACTIONS_URL` is `github`.
-And it can be changed to `self` to make it `root_url_of_your_gitea/actions/checkout@v3`.
+`DEFAULT_ACTIONS_URL` indicates where should we find the relative path action plugin. i.e. when use an action in a workflow file like

-Please note that using `self` is not recommended for most cases, as it could make names globally ambiguous.
-Additionally, it requires you to mirror all the actions you need to your Gitea instance, which may not be worth it.
-Therefore, please use `self` only if you understand what you are doing.
+```yaml
+name: versions
+on:
+  push:
+    branches:
+      - main
+      - releases/*
+jobs:
+  build:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v3
+```

-In earlier versions (<= 1.19), `DEFAULT_ACTIONS_URL` cound be set to any custom URLs like `https://gitea.com` or `http://your-git-server,https://gitea.com`, and the default value was `https://gitea.com`.
-However, later updates removed those options, and now the only options are `github` and `self`, with the default value being `github`.
-However, if you want to use actions from other git server, you can use a complete URL in `uses` field, it's supported by Gitea (but not GitHub).
-Like `uses: https://gitea.com/actions/checkout@v3` or `uses: http://your-git-server/actions/checkout@v3`.
+Now we need to know how to get actions/checkout, this configuration is the default git server to get it. That means we will get the repository via git clone ${DEFAULT_ACTIONS_URL}/actions/checkout and fetch tag v3.
+
+To help people who don't want to mirror these actions in their git instances, the default value is https://gitea.com
+To help people run actions totally in their network, they can change the value and copy all necessary action repositories into their git server.
+
+Of course we should support the form in future PRs like
+
+```yaml
+steps:
+  - uses: gitea.com/actions/checkout@v3
+```
+
+although Github don't support this form.
