+# About this guide
+
+This guide provides basic rooting procedure in details. If you are new, this is the right place to start.
+
+# Requirements
+
+### Software
+
+You need to install `python 3`.
+
+You also need to do the following after getting `python 3`:
+
+```
+pip install httpsig pyserial
+```
+
+If you have Windows PC, make sure your PATH environment is correct so you can run `python` and `pip` properly.
+
+### Hardware
+
+You need your DPT device, of course. And you need a microUSB cable that can connect your DPT to your computer.
+
+You also need the DPT to be charged at least 80%.
+
+# Steps
+
+For the following steps, we assume your device boots up normally, and has connected to WiFi. We also assumed you installed the official DPA software, at default locations.
+
+### 0x1 Validate Successful Connection
+
+In your laptop/desktop terminal, run `python dpt-tools.py -ip <DPT ip address>` to validate a successful connection. 
+
+For example, `python dpt-tools.py -ip 192.168.2.100`. You can find the ip address of DPT via your router, or in DPT settings.
+
+You can also specify your id and key files by:
+```
+python dpt-tools.py -id <deviceid file path> -k <your key file path> -ip <ip address>
+```
+Please refer to [janten's dpt-rp1-py](https://github.com/janten/dpt-rp1-py) on how do you get `deviceid` and `key` file path for your device.
+
+Then you will enter the interactive shell mode.
+
+### 0x2 Obtain Diagnosis Access
+
+In the shell, type `root` and press Enter. Follow the instructions. 
+
+It'll ask first if you have disabled the OTG id check, type `no` to proceed.
+
+After success, it'll ask you to confirm proceeding, press Enter key directly.
+
+Once success, do NOT re-run this. If it fails at the first part, re-run and answer `no` to the first question; if it fails at the second part, re-run `root` and answer `yes` to the first question.
+
+### 0x3 Enter Diagnosis Mode
+
+To enter diagnosis mode, type `diagnosis` and follow the instructions. 
+
+If tool exited by accident, directly use:
+```
+python dpt-tools.py --diagnosis
+```
+
+If things went smoothly, you are now in diagnosis mode in the shell.
+
+### 0x4 Patch the Updater Script
+
+In the shell, type `patch-updater-bash`. It is necessary to (partially) prevent a permanent brick. 
+
+Once done, do NOT got back to step `0x2` and re-run the command. It may cause a permanent brick, as someone reported.
+
+Up till here, you have full control over your device (rooted).
+
+### 0x5 Obtain ADB Access (Optional, Subject to Change)
+
+If you want to install customized apps on your own, proceed. Otherwise you can stop here, and wait for flash-able PKGs coming out.
+
+Make sure your system version is `1.4.01.16100` (for RP1) or `1.4.02.09061` (for CP1). If not, wait for corresponding modifications out.
+
+You will need to modify your Android boot partition.
+
+First backup your boot partition via `backup-bootimg`. Follow the instructions.
+
+And then type `restore-bootimg` and follow the instructions, using `boot-1.4.01.16100-mod-happyz-181214.img` in `python_api/assets`.
+
+After success, reboot the device by `reboot &` and quit the tool (by pressing `Ctrl + C`, or `quit`).
+
+On your laptop/desktop, do the following (Mac or Linux):
+```
+mv ~/.android/adbkey ~/.android/adbkey_bak
+cp python_api/assets/adbkey ~/.android/adbkey
+adb kill-server
+adb devices
+```
