-Learn how to publish your Fern Go SDK to the NPM registry. 
+Publish your public-facing Fern GO SDK to the [Pkgsite
+registry](https://pkg.go.dev/). After following the steps on this page,
+you'll have a versioned package published on Pkgsite.
 
-<Warning>This page is a WIP, please refer to our previous [documentation](https://buildwithfern.com/learn/sdks/guides/publish-a-public-facing-sdk).</Warning>

+<Info>This guide assumes that you already have an initialized `fern` folder on your local machine. If you don’t, run `fern init`. See [Go Quickstart](quickstart.mdx) for more details.</Info>
+
+
+## Set up your GitHub integration
+
+  1.   Create a new GitHub repository called `company-go` (or something similar) for your SDK, if you haven't done so already. Make sure your repository has:
+        *  **Public** visibility
+        *  A required license (e.g. [MIT](https://opensource.org/license/mit), [Apache](https://www.apache.org/licenses/LICENSE-2.0)) to the repository.
+  1.   Install the [Fern GitHub App](https://github.com/apps/fern-api): Select **Configure**, then scroll down to **Repository Access**. Select **Only select repositories** and in the dropdown select the repository for your SDK. Click **Save**. 
+  
+
+## Configure `generators.yml`
+
+<Steps>
+
+	<Step title="Run `fern add <generator>`">
+
+	  Navigate to your `generators.yml` on your local machine. Your `generators.yml` lives inside of your `fern` folder and contains all the configuration for your Fern generators. 
+
+	  Add a new generator to `generators.yml`:
+
+
+	    ```bash
+	    fern add fern-go-sdk --group go-sdk
+	    ```
+
+	  Once the command completes, you'll see a new group created in your `generators.yml`:
+
+    ```yaml {2-11}
+    groups:
+      go-sdk:
+      generators:
+        - name: fernapi/fern-go-sdk
+          version: <Markdown src="/snippets/version-number.mdx"/>
+          output:
+            location: local-file-system
+            path: ../sdks/go
+          config:
+            module:
+            path: sdk
+    ```
+
+	  </Step>
+
+	  <Step title="Configure `output` location">
+
+        Go publishes via Git repositories, so remove the auto-generated
+        `output` and `config` properties. Instead, add the path to your
+        GitHub repository: 
+
+	    ```yaml {6-7}
+	    groups: 
+	      go-sdk:
+	        generators:
+	          - name: fernapi/fern-go-sdk
+	            version: <Markdown src="/snippets/version-number.mdx"/>
+	            github:
+                  repository: devalog/company-go
+
+	    ```
+	  </Step>
+	    
+  </Steps>
+
+
+## Release your SDK to Pkgsite
+
+  At this point, you're ready to generate a release for your SDK.
+
+<Steps>
+ 
+	<Step title="Generate your release">
+
+	Regenerate your SDK and publish it on PyPI:
+
+	```bash
+	fern generate --group go-sdk --version <version>
+	```
+    Local machine output will verify that the release is pushed to your
+    repository and tagged with the version you specified. 
+
+    </Step>
+
+    <Step title="Publish on Pkgsite">
+    
+    Navigate to `https://pkg.go.dev/github.com/<github-org>/<github-repo-name>/` and send a request to index your package. In a few minutes, your new release should be published to [https://pkg.go.dev/](https://pkg.go.dev/)!
+
+    <Tip>After releasing a new version, it may take a few minutes for Pkgsite
+    to index and display the update. You can also try checking to see if the Go
+    proxy has indexed your module at
+    `https://proxy.golang.org/github.com/<github-org>/<github-repo-name>/@v/list`. Pkgsite
+    indexing usually happens within 5-15 min of the proxy picking it up. For
+    more information, see Go's documentation on [Adding a
+    package](https://pkg.go.dev/about#adding-a-package). </Tip> 
+
