+# User Guide
+
+## 1. Prepare Domain Certificates
+
+Prepare a domain certificate using tools like `acme.sh`, `certbot`, or manual upload. Modify the configurations as needed.  
+
+The certificate domain should correspond to the mail server's `MX` hostname, such as `mail.example.com`.
+
+
+## 2. Create Docker Volume
+```
+docker volume create maddydata 
+```
+
+## 3. Install the Application
+
+Install the application from the app store.
+
+The first installation may show an error and the container may not run properly due to missing certificate files. 
+
+Ignore the error and proceed to the next step.
+
+
+## 4. Place the Domain Certificate into the Volume
+
+The default path for the volume is:`/var/lib/docker/volumes/maddydata/_data/`
+
+```
+# Enter the volume path
+cd $(docker volume inspect maddydata --format '{{.Mountpoint}}')
+
+# Create certificate folder
+mkdir -p tls
+```
+Upload the certificate and private key to the tls folder, and rename them as:
+- fullchain.pem
+- privkey.pem
+
+Once the certificates are correctly uploaded, the container will automatically start running.
+
+## 5. Configure DKIM DNS Records
+### 5.1 Retrieve DKIM Values
+
+After the container starts running, check the path:`/var/lib/docker/volumes/maddydata/_data/dkim_keys`
+
+You will find a file named like `example.com_default.dns`.
+
+This file contains the required DKIM information.
+
+- Make sure to modify the domain as needed.
+
+To view the contents in the terminal:
+```
+cat /var/lib/docker/volumes/maddydata/_data/dkim_keys/example.com_default.dns 
+```
+
+Example output:
+```
+default._domainkey.example.org.    TXT   "v=DKIM1; k=ed25519; p=nAcUUozPlhc4VPhp7hZl+owES7j7OlEv0laaDEDBAqg="
+```
+
+### 5.2  Set DNS TXT Record
+
+Set the `DNS records` based on the retrieved information.
+
+For example:
+Add a `TXT` record for `default._domainkey.example.com` with the value `v=DKIM1; k=ed25519; p=nAcUUozPlhc4VPhp7hZl+owES7j7OlEv0laaDEDBAqg=`.
+
+## 6. Set DNS Records
+
+- Ensure modifications as needed.
+
+| Record Type | Domain  | Value                                                       |
+|-------------| --- |-------------------------------------------------------------|
+| A           | `mail.example.com` | `Server IPv4 Address`                                       |
+| A           | `example.com` | `Server IPv4 Address`                                       |
+| AAAA        | `mail.example.com` | `Server IPv4 Address (if available)`                        |
+| AAAA        | `example.com` | `Server IPv4 Address (if available)`                        |
+| MX          | `example.com` | `mail.example.com`                                          |
+| TXT         | `mail.example.com` | `v=spf1 mx ~all`                                            |
+| TXT         | `example.com` | `v=spf1 mx ~all`                                            |
+| TXT         | `_dmarc.example.com` | `v=DMARC1; p=quarantine; ruf=mailto:postmaster@example.com` |
+| TXT         | `_mta-sts.example.com` | `v=STSv1; id=1`                                             |
+| TXT         | `_smtp._tls.example.com` | `v=TLSRPTv1;rua=mailto:postmaster@example.com`              |
+
+## 7. Create Sending Accounts
+
+Access the container terminal via the `Containers` panel and execute the following commands:
+
+- Ensure modifications as needed.
+
+```
+maddy creds create postmaster@example.com
+
+maddy imap-acct create postmaster@example.com 
+```

+# Palworld Server Management Tool
+
+**Manage dedicated Palworld servers with a visual interface and REST API.**
+
+Features and Roadmap Based on `Level.sav` Save File Parsing:
+
+- [x] Complete player data
+- [x] Player Pal data
+- [x] Guild data
+
+Features Based on Official RCON Commands (Server-Only):
+
+- [x] Retrieve server information
+- [x] View online player list
+- [x] Kick/ban players
+- [x] In-game broadcasting
+- [x] Smoothly shut down the server with broadcasted messages
+
+This tool uses **bbolt** single-file storage to periodically fetch and store data from RCON and `Level.sav` files. 
+
+It provides a simple visual interface and REST API, making management and development easier.
+
+Ensure that private server RCON is enabled by following the instructions in the [official guide](https://github.com/zaigie/palworld-server-tool?tab=readme-ov-file#%E5%A6%82%E4%BD%95%E5%BC%80%E5%90%AF%E7%A7%81%E6%9C%8D-rcon).
+
+---
+
+Notes on Save File Parsing
+
+> Parsing the `Level.sav` save file temporarily requires a certain amount of system memory (1GB~3GB) for short periods (<20s). The memory is released after the task is completed. Ensure your server has sufficient memory. If not, consider the following alternatives:
+
+1. Deploy the tool on a separate server.
+2. Use a local personal computer for deployment.
+3. Opt for either of the above when the game server's performance is insufficient.
+
+By default, the **PST tool and the game server are assumed to run on the same physical machine**. For separate deployments, refer to the following resources:
+
+- [PST-Agent Deployment Guide](https://github.com/zaigie/palworld-server-tool/blob/main/README.agent.md)
+- [Sync Save Files from k8s Pod](https://github.com/zaigie/palworld-server-tool?tab=readme-ov-file#%E4%BB%8E-k8s-pod-%E5%90%8C%E6%AD%A5%E5%AD%98%E6%A1%A3)
