 ## Docusaurus Chart Setup
 
-### Container Configuration
+### Environment variables
 
-- Enter Docusaurus or Website Name
-- Docusaurus Default Template is generally `classic` unless you've manually installed another
-- Choose `Production` mode or `Development` mode
+- WEBSITE_NAME: Your website name
+- TEMPLATE: Docusaurus Default Template is generally `classic` unless you've manually installed another
+- RUN_MODE: Choose between `production` and `development` mode

-### Networking and Services

-- Leave defaults unless using Ingress then `ClusterIP` is recommended
+```yaml
+workload:
+  main:
+    podSpec:
+      containers:
+        main:
+          env:
+            WEBSITE_NAME: "Docusaurus HomeLab Website"
+            TEMPLATE: classic
+            RUN_MODE: development
+```
 
 ### Storage and Persistance
 
-- This chart uses `PVC` for storage as most of our charts do for `Storage`. However some may want to edit certain files or directories more often. This can be done with `Configure Additional Storage`.
-  - Click `Add` under `Configure App Additional Storage`
-  - Add the `Host Path` of the folder you wish to use
-  - Use the `Mount Path` of the folder you wish to have accessible. For example `/docusaurus/website/docs` mounts the files inside the `/docs` of the standard Docusaurus website.
+This chart uses PVC for storage, as do most of our charts. However, some users may need to frequently edit certain files or directories.
+A simple way to edit files inside the container is by using our [CodeServer](/guides/addons/code-server) Add-on. It provides a web-based file editor and is intended for temporary use, allowing you to add or remove it at any time.
 
-![Storage](./img/Storage.png)
+While it is possible to mount a specific folder to an external storage location, such as an NFS share, this approach is not recommended as it adds complexity. By default, the PVC mounts **/docusaurus**, meaning all files in **/docusaurus/website/docs** are stored within the PVC. If you choose to mount an external share, you must ensure that the required files are manually placed in the new location, as they will not be copied over automatically.
 
-### Ingress
-
-Recommended for use with a domain name but not required as mentioned above. You can refer to our Quick-Start Guides for an overview on using Ingress with your chart.
+```yaml
+persistence:
+  docs:
+    enabled: true
+    type: nfs
+    path: ${NFS_PATH}
+    server: ${SERVER_IP}
+    mountPath: /docusaurus/website/docs
+```
