+# Verdaccio and Apache2
+
+Running `verdaccio` via reverse proxy is a common practice. This configuration provides a quick way to run the application through **apache2** as reverse proxy.
+
+To run the containers, run the following command in this folder, it should start the containers in detach mode.
+
+```bash
+ docker-compose up -d
+```
+
+To recreate the nginx image you can force the build.
+
+```bash
+ docker-compose up --build -d
+
