-               A. reproduce and Share the Licensed Material, in whole or in part, for NonCommercial purposes only; and
-
-               B. produce, reproduce, and Share Adapted Material for NonCommercial purposes only.

-
-          6. No endorsement. Nothing in this Public License constitutes or may be construed as permission to assert or imply that You are, or that Your use of the Licensed Material is, connected with, or sponsored, endorsed, or granted official status by, the Licensor or others designated to receive attribution as provided in Section 3(a)(1)(A)(i).
-
-     b.	Other rights.
-
-          1. Moral rights, such as the right of integrity, are not licensed under this Public License, nor are publicity, privacy, and/or other similar personality rights; however, to the extent possible, the Licensor waives and/or agrees not to assert any such rights held by the Licensor to the limited extent necessary to allow You to exercise the Licensed Rights, but not otherwise.

+
+## What is h5ai
+
+I'd like to quote the [official website](https://larsjung.de/h5ai/).
+> h5ai is a modern file indexer for HTTP web servers with focus on your files. Directories are displayed in a appealing way and browsing them is enhanced by different views, a breadcrumb and a tree overview. Initially h5ai was an acronym for HTML5 Apache Index but now it supports other web servers too.
+
+## What this project provided for
+
+I hope this project would be useful for those who uses Docker for building their server.
+
+## Features
+
+### Core packages
+
+I choose Alpine Linux as a base image to make it a **light-weight** service.
+And I do choose Nginx-Alpine to get the benefits from some tweaks of Nginx version.
+
+So this is composed of,
+
+* Alpine Linux 3.19
+* Nginx 1.27.0
+* PHP 8.2.20
+
+with,
+
+* h5ai 0.30.0
+
+And to gather all of these into one together I use supervisor that manages all of these processes.
+
+### All functions work
+
+![all functions work](docs/docker-h5ai-functions.png)
+h5ai supports extensional functions such as showing thumnails of audio and video, caching for better speed, etc. This image activates all of those functions.
+
+### PHP 8 JIT enabled
+
+![jit enabled](docs/docker-h5ai-php-jit.png)
+JIT compiler that is introduced in PHP 8 is enabled by default.
+
+### Supports multiple architectures
+
+It builds from Github Actions for supporting multiple architectures such as AMD64(x86_64) and ARM64, ARMv7, ARMv6.
+
+So that you can use this on most computers supporting Docker.
+
+## How can I use this
+
+First of all, it assumes that you have installed Docker on your system.
+
+### Pulling the Docker image
+
+Pull the image from docker hub with the following command.
+
+```bash
+docker pull awesometic/h5ai
+```
+
+### Basic usage
+
+This is how it can be a service, in the other word, a container.
+
+You can run it using the following command.
+
+```bash
+docker run -it --rm \
+-p 80:80 \
+-v /shared/dir:/h5ai \
+-v /config/dir:/config \
+-e PUID=$UID \
+-e PGID=$GID \
+-e TZ=Asia/Seoul \
+awesometic/h5ai
+```
+
+The `--rm` option in the command is added to remove the executed container since this is an example usage.
+
+Basically, two directories should be mapped to the host PC.
+
+* `/h5ai`: This will be where the shared files located.
+* `/config`: This will be where stores configurations of h5ai and Nginx settings.
+
+And you should set proper **PUID** and **PGID**. If those not set up, the default UID, GID, the number 911, will be used for the `/config` directory. Not setting PUID/PGID will not significantly affect its operations, but setting up the proper number is still recommended.
+
+Or you can handle some directories that has special permissions using these PUID/PGID.
+
+If you want to run this image as a daemon, use `-d` option. See the following command.
+
+```bash
+docker run -d --name=h5ai \
+-p 80:80 \
+-v /shared/dir:/h5ai \
+-v /config/dir:/config \
+-e PUID=$UID \
+-e PGID=$GID \
+-e TZ=Asia/Seoul \
+awesometic/h5ai
+```
+
+If you want to run this image permanently, so to speak, to keep it runs after rebooting the server, you can use `--restart unless-stopped` option. See the following command.
+
+```bash
+docker run -d --name=h5ai \
+-p 80:80 \
+-v /shared/dir:/h5ai \
+-v /config/dir:/config \
+-e PUID=$UID \
+-e PGID=$GID \
+-e TZ=Asia/Seoul \
+--restart unless-stopped \
+awesometic/h5ai
+```
+
+### Keep in safe from anonymous
+
+If you want to login when visiting the hosted h5ai website so that implement protection from accessing anonymous users, add `HTPASSWD` environments like the below.
+
+```bash
+docker run -it --name=h5ai \
+-p 80:80 \
+-v /shared/dir:/h5ai \
+-v /config/dir:/config \
+-e PUID=$UID \
+-e PGID=$GID \
+-e TZ=Asia/Seoul \
+-e HTPASSWD=true \
+-e HTPASSWD_USER=awesometic \
+awesometic/h5ai
+```
+
+Then only the user set by `HTPASSWD_USER`, **awesometic** can access this h5ai website with these options.
+
+Be aware of that the `HTPASSWD` environment variable must be **true** for authentication.
+
+And aware of this too that you have to run in interaction mode by adding **-it** to set a password for the newly created user for the first time.
+
+Or, you can set the password for Htpasswd by passing an environment variable. In this case, you shouldn't have to use **-it** option because it is not needed at all.
+
+### Use it as a real-time service
+
+Consequently, if you want to run this image as a real-time service, check the following command.
+
+```bash
+docker run -d --name=h5ai \
+-p 80:80 \
+-v /shared/dir:/h5ai \
+-v /config/dir:/config \
+-e PUID=$UID \
+-e PGID=$GID \
+-e TZ=Asia/Seoul \
+-e HTPASSWD=true \
+-e HTPASSWD_USER=awesometic \
+-e HTPASSWD_PW=awesometic \
+--restart unless-stopped \
+awesometic/h5ai
+```
+
+### Visit your website
+
+To do the test drive, when the container runs then just let your browser browses:
+
+``` http
+http://localhost/
+```
+
+![Sample files from https://www.sample-videos.com/](docs/docker-h5ai-demo.png)
+After all, you can see the directories you shared.
+
+## Caution when update
+
+**If the new h5ai version releases**, I overwrite all the updated files to the corresponded directories on the project folder. In this sequence, some customized files by you will be replaced into the new one.
+
+So it is **highly recommended to make back up files of your edits** before update the Docker image.
+
+To prevent an unexpected accident, I put minimal protection into my `init.sh` script. This checks if the current `private/conf/options.json` file is outdated from the current about to be run. If the current `options.json` is older than the newly loaded one, the script makes its backup file under the `/config` directory. See the followings.
+
+```bash
+awesometic@awesometic-nas:docker/h5ai $ ll
+total 32K

+But since I don't know how much the users edit their h5ai files like layout or style, it won't make backups for all of the h5ai related files. So it depends on your caution.
+
+If you have any good idea, please let me know. 😀
+
+## Use with HTTPS (SSL)
+
+It is highly recommended to use this web service with HTTPS for data encryption. Without SSL, the attackers can see your data streams even if you set the htpasswd to authenticate to the web page.
+
+In this image, it is not provide any HTTPS related settings but you can set HTTPS with another web server. The most frequently used thing for HTTPS is a reverse proxy server, which can be set easiliy with a docker image called [SWAG from LinuxServer.io](https://hub.docker.com/r/linuxserver/swag).
+
+## TODOs
+
+* [x] Easy access to options.json
+* [x] Access permission using htpasswd
+* [x] Setup PUID/PGID to better handle the permissions
+* [ ] Expose Nginx, PHP log files to the host

+# h5ai
+
+[![license][license-img]][github] [![web][web-img]][web] [![github][github-img]][github]
+
+A modern HTTP web server index for Apache httpd, lighttpd, and nginx.
+
+
+## Important
+
+* Do **not** install any files from the `src` folder, they need to be
+  preprocessed to work correctly!
+* Find a preprocessed package and detailed install instructions on the
+  [project page][web].
+* For bug reports and feature requests please use [issues][github-issues].
+
+
+## Build
+
+There are installation ready packages for the latest [releases][release] and
+[dev builds][develop]. But to build **h5ai** yourself either `git clone` or
+download the repository. From within the root folder run the following
+commands to find a fresh zipball in folder `build` (tested on linux only,
+requires [`node 10.0+`][node] to be installed, might work on other
+configurations).
+
+~~~sh
+> npm install
+> npm run build
