 #### 使用说明

+**Terminal 1**: Create user/network/mount namespaces
+
+```console
+(host)$ unshare --user --map-root-user --net --mount
+(namespace)$ echo $$ > /tmp/pid
+```
+
+In this documentation, we use `(host)$` as the prompt of the host shell, `(namespace)$` as the prompt of the shell running in the namespaces.
+
+If `unshare` fails, try the following commands (known to be needed on Debian, Arch, and old CentOS 7.X):
+
+```console
+(host)$ sudo sh -c 'echo "user.max_user_namespaces=28633" >> /etc/sysctl.d/userns.conf'
+(host)$ [ -f /proc/sys/kernel/unprivileged_userns_clone ] && sudo sh -c 'echo "kernel.unprivileged_userns_clone=1" >> /etc/sysctl.d/userns.conf'
+(host)$ sudo sysctl --system
+```
+
+**Terminal 2**: Start slirp4netns
+
+```console
+(host)$ slirp4netns --configure --mtu=65520 --disable-host-loopback $(cat /tmp/pid) tap0
+starting slirp, MTU=65520
+...
+```
