 This self-hosted QuickChart implementation currently supports the `/chart`, `/qr`, and `/graphviz` endpoints.  Other endpoints such as `/wordcloud`, `watermark`, `/chart/create` are not available in this version due to non-OSS 3rd-party dependencies.
 
+**Note:** This release adds `/chart/create/` and `/chart/render/` functionality. For data storage, sqlite db is used.
+It supports functionality as described [here](https://quickchart.io/documentation/usage/short-urls-and-templates/#short-urls) and [here](https://quickchart.io/documentation/usage/short-urls-and-templates/#templates)
+
+Example body for `/chart/create/`:
+
+```json
+{
+  "chart": {
+    "options": {
+      "title": {
+        "display": true,
+        "text": "Chart Title"
+      }
+    },
+    "type": "bar",
+    "data": {
+      "labels": [
+        "A",
+        "B"
+      ],
+      "datasets": [
+        {
+          "data": [
+            10,
+            20
+          ]
+        }
+      ]
+    }
+  },
+  "neverExpire": true
+}
+```
+
+The **neverExpire** parameter allows you to control the expiration time of the saved chart. 
+If **"neverExpire": true**, then the chart has no storage time restrictions, otherwise, if this parameter is not specified or is false, then the expiraton time will be set to 6 months.
+
+To run it with docker:
+```shell
+docker build -t quickchart .   
+docker run -p 3400:3400  -v /path/to/db/folder/:/var/lib/db/ quickchart
+```
