    -   This means you are using a UI with HTTPS and your registry is using HTTP (unsecured). When you are on a HTTPS site, you can't get HTTP content. Upgrade you registry with a HTTPS connection.
 -   Why the default nginx `Host` is set to `$http_host` ?
    -   This fixes the issue [#88](https://github.com/Joxit/docker-registry-ui/issues/88). More about this in [#113](https://github.com/Joxit/docker-registry-ui/issues/113).
-   Why DELETE fails with 401 status code (using Basic Auth) ?
-    -   This is caused by a bug in docker registry, I suggest to have your UI on the same domain than your registry e.g. registry.example.com/ui/. (see [#104](https://github.com/Joxit/docker-registry-ui/issues/104)).
+-   Why OPTIONS (aka preflight requests) and DELETE fails with 401 status code (using Basic Auth) ?
+    -   This is caused by a bug in docker registry, it returns 401 status requests on preflight requests, this breaks [W3C preflight-request specification](https://www.w3.org/TR/cors/#preflight-request). I suggest to have your UI on the same domain than your registry e.g. registry.example.com/ui/ **or** use `NGINX_PROXY_PASS_URL` **or** configure a nginx/apache/haproxy in front of your registry that returns 200 on each OPTIONS requests. (see [#104](https://github.com/Joxit/docker-registry-ui/issues/104), [#204](https://github.com/Joxit/docker-registry-ui/issues/204), [#207](https://github.com/Joxit/docker-registry-ui/issues/207), [#214](https://github.com/Joxit/docker-registry-ui/issues/214), [#266](https://github.com/Joxit/docker-registry-ui/issues/266)).
 -   Can I use the docker registry ui as a standalone application (with Electron) ?
    -   Yes, check out the example [here](https://github.com/Joxit/docker-registry-ui/tree/main/examples/electron). (see [#129](https://github.com/Joxit/docker-registry-ui/pull/129))
 -   I deleted images through the UI, but they are still present on the server. How can I delete them?
    - When you delete an image with the UI, only the reference is deleted and not the content. To remove dangling images, you need to run the garbage collector of the registry with the command `registry garbage-collect config.yml` or `docker exec registry registry garbage-collect config.yml`. (see [#77](https://github.com/Joxit/docker-registry-ui/issues/77) [#147](https://github.com/Joxit/docker-registry-ui/issues/147))
 -   Why when I delete one tag, all tags with the same SHA are deleted ?
    - This a docker registry API limitation, there is only one way to [delete images with tag](https://docs.docker.com/registry/spec/api/#deleting-an-image), it's by its `name` and its `manifest` (it's a sha of the content). So when you delete a tag, this will delete all tags of this image with the same SHA/manifest.
+-   Can I run the container with an unprivileged user ?
+    - Yes you can run the container with the `nginx` user, (see [#224](https://github.com/Joxit/docker-registry-ui/issues/224)).

 ## Available options

+You can run the container with the unprivileged user `nginx`, see the discussion [#224](https://github.com/Joxit/docker-registry-ui/issues/224).

 Some env options are available for use this interface for **only one server**.

 - `REGISTRY_URL`: The default url of your docker registry. You may need CORS configuration on your registry. This is usually the domain name or IP of your registry reachable by your computer (e.g `http://registry.example.com`). (default: derived from the hostname of your UI).
 - `REGISTRY_TITLE`: Set a custom title for your user interface. (default: value derived from `REGISTRY_URL`).
 - `PULL_URL`: Set a custom url when you copy the `docker pull` command. (default: value derived from `REGISTRY_URL`).
 - `DELETE_IMAGES`: Set if we can delete images from the UI. (default: `false`)
- `SHOW_CONTENT_DIGEST`: Show content digest in docker tag list. (default: `true`)
+- `SHOW_CONTENT_DIGEST`: Show content digest in docker tag list. (default: `false`)
 - `CATALOG_ELEMENTS_LIMIT`: Limit the number of elements in the catalog page. (default: `100000`).
- `SINGLE_REGISTRY`: Remove the menu that show the dialogs to add, remove and change the endpoint of your docker registry. (default `false`)
+- `SINGLE_REGISTRY`: Remove the menu that show the dialogs to add, remove and change the endpoint of your docker registry. (default: `false`).
 - `NGINX_PROXY_PASS_URL`: Update the default Nginx configuration and set the **proxy_pass** to your backend docker registry (this avoid CORS configuration). This is usually the name of your registry container in the form `http://registry:5000`.
- `NGINX_PROXY_HEADER_*`: Update the default Nginx configuration and set **custom headers** for your backend docker registry. Only when `NGINX_PROXY_PASS_URL` is used.
+- `NGINX_PROXY_HEADER_*`: Update the default Nginx configuration and **set custom headers** for your backend docker registry. Only when `NGINX_PROXY_PASS_URL` is used.
+- `NGINX_PROXY_PASS_HEADER_*`: Update the default Nginx configuration and **forward custom headers** to your backend docker registry. Only when `NGINX_PROXY_PASS_URL` is used.
+- `NGINX_LISTEN_PORT`: Listen on a port other than 80. (default: `80` when the user is root, `8080` otherwise).
+- `DEFAULT_REGISTRIES`: List of comma separated registry URLs (e.g `http://registry.example.com,http://registry:5000`), available only when `SINGLE_REGISTRY=false`. (default: ` `).
+- `READ_ONLY_REGISTRIES`: Desactivate dialog for remove and add new registries, available only when `SINGLE_REGISTRY=false`. (default: `false`).
+- `SHOW_CATALOG_NB_TAGS`: Show number of tags per images on catalog page. This will produce + nb images requests, not recommended on large registries. (default: `false`).
+- `HISTORY_CUSTOM_LABELS`: Expose custom labels in history page, custom labels will be processed like maintainer label.
+- `USE_CONTROL_CACHE_HEADER`: Use `Control-Cache` header and set to `no-store, no-cache`. This will avoid some issues on multi-arch images (see [#260](https://github.com/Joxit/docker-registry-ui/issues/260)). This option requires registry configuration: `Access-Control-Allow-Headers` with `Cache-Control`. (default: `false`).

 # docker-registry-ui

-[docker-registry-ui](https://joxit.dev/docker-registry-ui/) is the simplest and most complete UI for your private registry!
+:warning: The official helm chart is now located at https://helm.joxit.dev and on GitHub [github.com/Joxit/helm-charts](https://github.com/Joxit/helm-charts).

+## Usage

-## TL;DR;
+1. Add my Helm repository (named `joxit`)

-```bash
-$ helm install .
+```
+helm repo add joxit https://helm.joxit.dev
 ```

-## Introduction
+2. Ensure you have access to the Helm chart and you see the latest chart version listed. If you have previously added the Helm repository, run `helm repo update`.

-This chart bootstraps a [docker-registry-ui](https://joxit.dev/docker-registry-ui/) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
-
-It also may deploy the [docker registry](https://docs.docker.com/registry/) if you havent have one already.
-
-## Prerequisites
-
- Kubernetes 1.9+ with Beta APIs enabled
- PV provisioner support in the underlying infrastructure
-
-## Installing the Chart
-
-To install the chart with the release name `my-release`:
-
-```bash
-$ helm update --install my-release .
+```
+helm search repo joxit/docker-registry-ui
 ```

-The command deploys docker-registry-ui on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation.
+3. Now you're ready to install the Docker Registry UI! To install Docker Registry UI with the default configuration using Helm 3.2 run the following command below. This will deploy the Docker Registry UI on the default namespace.

-> **Tip**: List all releases using `helm list`
-
-## Uninstalling the Chart
-
-To uninstall/delete the `my-release` deployment:
-
-```bash
-$ helm delete my-release
 ```
-
-The command removes all the Kubernetes components associated with the chart and deletes the release.
-
-## Configuration
-
-The following table lists the configurable parameters of the Redmine chart and their default values.

-
-
-Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
-
-```bash
-$ helm upgrade --install my-release \
-  --set registry.external=true \
-  --set registry.url=http://registry.example.com:5000 \
-    .
+helm upgrade --install docker-registry-ui joxit/docker-registry-ui
 ```
-
-Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
-
-```bash
-$ helm upgrade --install my-release -f values.yaml .
-```
-
-> **Tip**: You can use the default [values.yaml](values.yaml)

+# Example for pull request #219
+
+Basic usage for `DEFAULT_REGISTRIES` and `READ_ONLY_REGISTRIES`.
+
+Behaviors: 
+- `DEFAULT_REGISTRIES`:
+    - will set the list of registries in the localstorage when the localstorage is empty.
+    - will overwrite the list of registries every time when  `READ_ONLY_REGISTRIES=true`
+- `READ_ONLY_REGISTRIES`:
+    - will remove dialog for Add and Remove registries
+
+These options works only when `SINGLE_REGISTRY=false`
+
