+# How to build Docker Registry UI
+
+This file contains tips to help you take (and understand) your first steps in Docker Registry UI development.
+
+## Clone and install the repository
+
+```bash
+git clone https://github.com/Joxit/docker-registry-ui.git
+cd docker-registry-ui
+npm install
+```
+
+## Run the local server
+
+```bash
+npm start
+```
+
+Open your browser <http://localhost:8000> you can configure your options by updating the `src/index.html` file.

     - You should add a CORS Policy on your bucket, check the issue [#193](https://github.com/Joxit/docker-registry-ui/issues/193).
 -   Why my docker registry server is returning an error `pagination number invalid` ?
     - Since docker registry server 2.8.2 there is default limit of 1000 images in catalog. If you need more images update the configuration `REGISTRY_CATALOG_MAXENTRIES` with your max value and check the issue [#306](https://github.com/Joxit/docker-registry-ui/issues/306).
+-   I'm using `NGINX_PROXY_PASS_URL`, my registry server has been recreated and the UI cannot connect with the message `[error] 176#176: *2 connect() failed (111: Connection refused) while connecting to upstream`, what can I do?
+    - Nginx get the IP of all addresses only once at runtime, since your container has been recreated, its IP changed too. To prevent this kind of issue, you may use the option `NGINX_RESOLVER` and set to `127.0.0.11`.
