Getting Started

Maple as a UWP app is distributed for sideloading only. When installed, it acts as a VPN provider which you will find in the VPN Settings. Use Maple app for configuration management, as well as adding external databases.

Install

1. Grab the latest package from Release page.
2. Extract everything from the package.
3. Right click the certificate (named Maple.App_x.y.z.0_x64.cer) and select Install Certificate.
4. On the Certificate Import Wizard, select Local Machine. Administrator privileges may be required to proceed.
5. Import the certificate to the Trusted Root Certification Authorities folder. Note: failure to import the certificate or choosing a wrong certificate store will prevent you from installing the app.
6. Open the AppxBundle (named Maple.App_x.y.z.0_x64.appxbundle) and follow the instructions until Maple is successfully installed on your computer.

Set up

1. Launch Maple from the Start menu.
2. Edit configuration. Refer to https://github.com/eycorsican/leaf/blob/master/README.zh.md for further explanation.
3. Save the configuration file.
4. If any EXTERNAL or GEOIP directive is used, drag external database files into Config area. V2Ray Domain List Community database can be fetched at https://github.com/v2ray/domain-list-community/releases/latest/download/dlc.dat . For GeoIP database, please go to MaxMind Developer Portal and sign up for free download.
5. Rename these databases accordingly (if applicable). By default, GeoIP database is geo.mmdb and V2Ray Domain List Community database is site.dat.
6. Go to Setting page in Maple. Choose your network adapter such as Ethernet or WLAN.
7. Launch Windows Settings app.
8. Add a VPN connection.
   • For VPN provider, choose Maple.
   • In the Connection name box, enter Maple.
   • In the Server name or address box, enter https://github.com/YtFlow/Maple .
   • Select Save.
9. If any Proxy Server has a loopback address (127.0.0.1 or ::1), make sure Loopback Exemption is enabled for Maple. See https://docs.microsoft.com/en-us/previous-versions/windows/apps/hh770532(v=win.10) .

Connect

• Simply click the toggle button on the title bar, or
• In Windows 11, select the battery, network, or volume icon to open the Quick Settings panel. Find Maple in VPN panel and connect, or
• In Windows 10, select the Network icon on the taskbar, and click Maple. In Windows Settings app, select Maple, and then Connect.
  

Note: Modifying the current configuration file while VPN is connected will take effect immediately.

• external entries
• VPN On Demand
• Configurable routing entries
• IPv6 support
