-## Claude Max Authentication
-
-This action supports authentication using Claude Max OAuth credentials. This allows users with Claude Max subscriptions to use their existing authentication.
-
-### Setup
-
-1. **Get OAuth Credentials**: Use Claude Code to generate OAuth credentials:
-
-   ```
-   /auth-setup
-   ```
-
-2. **Add Credentials to Repository**: Add the generated JSON credentials as a repository secret named `CLAUDE_CREDENTIALS`.
-
-It should look like this:
-
-```json
-{
-  "claudeAiOauth": {
-    "accessToken": "sk-ant-xxx",
-    "refreshToken": "sk-ant-xxx",
-    "expiresAt": 1748707000000,
-    "scopes": ["user:inference", "user:profile"]
-  }
-}
-```
-
-3. **Configure Workflow**: Set up your workflow to use OAuth authentication:
-
-```yaml
-- uses: markwylde/claude-code-gitea-action@v1.0.5
-  with:
-    anthropic_api_key: "use-oauth"
-    claude_credentials: ${{ secrets.CLAUDE_CREDENTIALS }}
-    gitea_token: ${{ secrets.GITEA_TOKEN }}
-```
-
-When `anthropic_api_key` is set to `'use-oauth'`, the action will use the OAuth credentials provided in `claude_credentials` instead of a direct API key.
-

-2. Anthropic OAuth credentials (Claude Max subscription)
+1. **Direct Anthropic API** (default) - Use your Anthropic API key
+2. **Claude Code OAuth Token** - Use OAuth token from Claude Code application
+
+### Using Claude Code OAuth Token
+
+If you have access to [Claude Code](https://claude.ai/code), you can use OAuth authentication instead of an API key:
+
+1. **Generate OAuth Token**: run the following command and follow instructions:
+   ```
+   claude setup-token
+   ```
+   This will generate an OAuth token that you can use for authentication.
+
+2. **Add Token to Repository**: Add the generated token as a repository secret named `CLAUDE_CODE_OAUTH_TOKEN`.
+
+3. **Configure Workflow**: Use the OAuth token in your workflow:

+```yaml
+- uses: markwylde/claude-code-gitea-action@v1.0.5

+
+When `claude_code_oauth_token` is provided, it will be used instead of `anthropic_api_key` for authentication.
