 Fork from [traefik-umami-plugin](https://github.com/1cedsoda/traefik-umami-plugin)
+
+
+# Installation
+To [add this plugin to traefik](https://plugins.traefik.io/install) reference this repository as a plugin in the static config.
+The version references a git tag.
+
+```yaml
+experimental:
+  plugins:
+    traefik-tianji-plugin:
+      moduleName: "github.com/msgbyte/traefik-tianji-plugin"
+      version: "v1.0.0" 
+```
+```toml
+[experimental.plugins.traefik-tianji-plugin]
+  moduleName = "github.com/msgbyte/traefik-tianji-plugin"
+  version = "v1.0.0"
+```
+With the plugin installed, you can configure a middleware in a dynamic configuration such as a `config.yml` or docker labels.
+Inside `traefik-tianji-plugin` the plugin can be configured.
+
+Only `tianjiHost` and `websiteId` options are required to get started.
+The middleware can then be used in a [router](https://doc.traefik.io/traefik/routing/routers/#middlewares_1). Remember to reference the correct [provider namespace](https://doc.traefik.io/traefik/providers/overview/#provider-namespace).

+
+```yaml
+http:
+  middlewares:
+    my-tianji-middleware:
+      plugin:
+        traefik-tianji-plugin:
+          tianjiHost: "https://app-tianji.msgbyte.com"
+          websiteId: "<your-website-id>"
