 ## Customization
 
-### Customize the image
+For any customization to take effect, you should "rebuild and reopen":
 
-You can make changes to the [Dockerfile](Dockerfile) and then rebuild the image. For example, your Dockerfile could be:
+1. Open the command palette in Visual Studio Code (CTRL+SHIFT+P)
+2. Select `Dev-Containers: Rebuild Container`
 
-```Dockerfile
-FROM qmcgaw/godevcontainer
-RUN apk add curl
-```
+Changes you can make are notably:
 
-To rebuild the image, either:
+- Changes to the Docker image in [Dockerfile](Dockerfile)
+- Changes to VSCode **settings** and **extensions** in [devcontainer.json](devcontainer.json).
+- Change the entrypoint script by adding a bind mount in [devcontainer.json](devcontainer.json) of a shell script to `/root/.welcome.sh` to replace the [current welcome script](https://github.com/qdm12/godevcontainer/blob/master/shell/.welcome.sh). For example:
 
-- With VSCode through the command palette, select `Remote-Containers: Rebuild and reopen in container`
-- With a terminal, go to this directory and `docker-compose build`
+    ```json
+    // Welcome script
+    {
+        "source": "/yourpath/.welcome.sh",
+        "target": "/root/.welcome.sh",
+        "type": "bind"

-### Customize VS code settings
-
-You can customize **settings** and **extensions** in the [devcontainer.json](devcontainer.json) definition file.
-
-### Entrypoint script
-
-You can bind mount a shell script to `/root/.welcome.sh` to replace the [current welcome script](https://github.com/qdm12/basedevcontainer/blob/master/shell/.welcome.sh).

-### Publish a port

-To access a port from your host to your development container, publish a port in [docker-compose.yml](docker-compose.yml). You can also now do it directly with VSCode without restarting the container.

-### Run other services

 ## Record creation
 
 In case you don't have an A or AAAA record for your host and domain combination, it will be created by DDNS-Updater.
-However, to do so, the corresponding ALIAS record, that is automatically created by Porkbun, is automatically deleted to allow this.
+
+Porkbun creates default DNS entries for new domains, which can conflict with creating a root or wildcard A/AAAA record. Therefore, ddns-updater automatically removes any conflicting default record before creating records, as described in the table below:
+
+| Record type | Owner | Record value | Situation requiring a removal |
+| --- | --- | --- | --- |
+| `ALIAS` | `@` | pixie.porkbun.com | Creating A or AAAA record for the root domain **or** wildcard domain |
+| `CNAME` | `*` | pixie.porkbun.com | Creating A or AAAA record for the wildcard domain |
+
