++ Fixed ACME snippet "Obtain Certificate" concurrent issues in save EAB and DNS credentials
+
+
+# v3.0.3 Apr 30 2024
+## Breaking Change
+
+For users using SMTP with older versions, you might need to update the settings by moving the domains (the part after @ in the username and domain setup field) into the username field.

-## Setup: </br>
-Although not required, it is recommended to give Zoraxy a dedicated location on the host to mount the container. That way, the host/user can access them whenever needed. A volume will be created automatically within Docker if a location is not specified. </br>
+## Usage
 
-You may also need to portforward your 80/443 to allow http and https traffic. If you are accessing the interface from outside of the local network, you may also need to forward your management port. If you know how to do this, great! If not, find the manufacturer of your router and search on how to do that. There are too many to be listed here. </br>
+If you are attempting to access your service from outside your network, make sure to forward ports 80 and 443 to the Zoraxy host to allow web traffic. If you know how to do this, great! If not, find the manufacturer of your router and search on how to do that. There are too many to be listed here. Read more about it from [whatismyip](https://www.whatismyip.com/port-forwarding/).
+
+In the examples below, make sure to update `/path/to/zoraxy/config/`. If a path is not provided, a Docker volume will be created at the location but it is recommended to store the data at a defined host location or a named Docker volume.
+
+Once setup, access the webui at `http://<host-ip>:8000` to configure Zoraxy. Change the port in the URL if you changed the management port.
+
+### Docker Run
 
-### Using Docker run </br>
 ```
-docker run -d --name (container name) -p (ports) -v (path to storage directory):/opt/zoraxy/data/ -e ARGS='(your arguments)' zoraxydocker/zoraxy:latest
+docker run -d \
+  --name zoraxy \
+  --restart unless-stopped \
+  -p 80:80 \
+  -p 443:443 \
+  -p 8000:8000 \
+  -v /path/to/zoraxy/config/:/opt/zoraxy/config/ \
+  -v /var/run/docker.sock:/var/run/docker.sock \
+  -v /etc/localtime:/etc/localtime \
+  -e FASTGEOIP="true" \
+  zoraxydocker/zoraxy:latest
 ```
 
-### Using Docker Compose </br>
+### Docker Compose
+
 ```yml
-version: '3.3'
 services:
-  zoraxy-docker:
-    image: zoraxydocker/zoraxy:latest
-    container_name: (container name)
-    ports:
-      - 80:80
-      - 443:443
-      - (external):8000
-    volumes:
-      - (path to storage directory):/opt/zoraxy/config/
-    environment:

-```
-
-| Operator | Need | Details |
-|:-|:-|:-|
-| `-d` | Yes | will run the container in the background. |
-| `--name (container name)` | No | Sets the name of the container to the following word. You can change this to whatever you want. |
-| `-p (ports)` | Yes | Depending on how your network is setup, you may need to portforward 80, 443, and the management port. |
-| `-v (path to storage directory):/opt/zoraxy/config/` | Recommend | Sets the folder that holds your files. This should be the place you just chose. By default, it will create a Docker volume for the files for persistency but they will not be accessible. |
-| `-e ARGS='(your arguments)'` | No | Sets the arguments to run Zoraxy with. Enter them as you would normally. By default, it is ran with `-noauth=false` but <b>you cannot change the management port.</b> This is required for the healthcheck to work. |
-| `zoraxydocker/zoraxy:latest` | Yes | The repository on Docker hub. By default, it is the latest version that is published. |

+
+### Building
+
+To build the Docker image:
+  - Check out the repository/branch.
+  - Copy the Zoraxy `src/` directory into the `docker/` (here) directory.
+  - Run the build command with `docker build -t zoraxy_build .`
+  - You can now use the image `zoraxy_build`
+    - If you wish to change the image name, then modify`zoraxy_build` in the previous step and then build again.

+# Example www Folder
+
+This is an example www folder that contains two sub-folders.
+
+- `html/`
+- `templates/`
+
+The html file contain static resources that will be served by Zoraxy build-in static web server. You can use it as a generic web server with a static site generator like [Hugo](https://gohugo.io/) or use it as a small CDN for serving your scripts / image that commonly use across many of your sites.
+
+The templates folder contains the template for overriding the build in error or access denied pages. The following templates are supported
+
+- notfound.html (Default site Not-Found error page)
+- whitelist.html (Error page when client being blocked by whitelist rule)
+- blacklist.html (Error page when client being blocked by blacklist rule)
+
+To use the template, copy and paste the `wwww` folder to the same directory as zoraxy executable (aka the src/ file if you `go build` with the current folder tree). 
+
+
+
+### Other Templates
+
+There are a few pre-built templates that works with Zoraxy where you can find in the `other-templates` folder. Copy the folder into `www` and rename the folder to `templates` to active them. 
+
+
+
+It is worth mentioning that the uwu icons for not-found and access-denied are created by @SAWARATSUKI
