 ### Usage

 #### Geoip and Geosite
-v2rayNG release already embedded domain file `geoip.dat` and `geosite.dat`. However it is (probably) not the latest and not the most complete list.
-For power user, the embedded files can be easily replaced with the following steps:
-1. Launch v2rayNG (v1.4.9+)
-2. Find existing geoip.dat and geosite.dat in `Android/data/com.v2ray.ang/files/assets` (path may differ on some Android device)
-3. Replace them with the latest [domain list](https://github.com/v2fly/domain-list-community) and [ip list](https://github.com/v2fly/geoip)
-4. Enhanced version can be found in this [repo](https://github.com/Loyalsoldier/v2ray-rules-dat) (recommend to use `geosite:geolocation-!cn` for proxy dns and routing)
-5. It is also possible to use third party dat file in the same folder, like [h2y](https://guide.v2fly.org/routing/sitedata.html#%E5%A4%96%E7%BD%AE%E7%9A%84%E5%9F%9F%E5%90%8D%E6%96%87%E4%BB%B6)
+- geoip.dat and geosite.dat files are in `Android/data/com.v2ray.ang/files/assets` (path may differ on some Android device)
+- download feature will get enhanced version in this [repo](https://github.com/Loyalsoldier/v2ray-rules-dat) (Note it need a working proxy)
+- latest official [domain list](https://github.com/v2fly/domain-list-community) and [ip list](https://github.com/v2fly/geoip) can be imported manually

yuhan6665	c6560e9bc0	Remove alterId field VmessQRCode "aid" is kept for backwards compatibility and always set to 0 Since 2022, new *ray server will reject alterId > 0. If it is enabled and set specifically > 0, for v2fly server v4.28.1+ and Xray server v1.0.0+, client with either 0 or above 0 can connect For older v2ray server, the default config will not work, user has to use custom config to set alterId.
