+### openSUSE
+Currently `vnote` on openSUSE Tumbleweed can be installed from `home:opensuse_zh` project on OBS. You can execute the following command directly:
+
+```shell
+sudo zypper ar https://download.opensuse.org/repositories/home:/opensuse_zh/openSUSE_Tumbleweed/ home:opensuse_zh
+sudo zypper ref
+sudo zypper in vnote
+```
+
+For other architectures, please search for `vnote` at [software.opensuse.org](https://software.opensuse.org).
+
+We don't support Leap 42 and below due to the Qt version. Please use AppImage or build it yourself.

+### openSUSE
+目前 openSUSE Tumbleweed 可以通过 OBS 上的 `home:opensuse_zh` 源直接安装。您可以直接执行以下命令：
+
+```shell
+sudo zypper ar https://download.opensuse.org/repositories/home:/opensuse_zh/openSUSE_Tumbleweed/ home:opensuse_zh
+sudo zypper ref
+sudo zypper in vnote
+```
+
+其他架构请直接在 [software.opensuse.org](https://software.opensuse.org) 搜索 `vnote`。
+
+由于 Leap 42 及以下版本的 Qt 版本过低，我们无法在 OBS 上进行打包。请使用 AppImage 或自行构建。
