+## Publishing Documentation
+
+### To docs.rs (Automatically)
+
+When you publish a crate to crates.io, its documentation is automatically built and hosted on [docs.rs](https://docs.rs). You do not need to do anything manually for this.
+
+### To Your Own Server
+
+To build the documentation as static HTML files for hosting on your own server (like GitHub Pages, Netlify, or AWS S3):
+
+1.  **Build Docs Locally:**
+    ```bash
+    cargo doc --no-deps --document-private-items
+    ```
+2.  **Locate the Output:**
+    The static HTML files will be located in the `target/doc` directory.
+3.  **Upload:**
+    You can copy this folder to any static web host. For example, using `scp`:
+    ```bash
+    scp -r target/doc/* user@your-server.com:/var/www/html/docs/

-When `cdd-rust` generates an SDK (e.g., via `cdd-rust from_openapi to_sdk`), you can publish the generated Rust crate to Crates.io.

-## Automated Updates
+## Updating the Generated Client SDK via GitHub Actions
 
-You can set up a GitHub Action cron job to periodically fetch the latest OpenAPI specification from your server, run `cdd-rust from_openapi to_sdk`, and push the changes if they differ.
+This workflow fetches the latest OpenAPI specification and regenerates the Rust client SDK automatically.
