   Ways to run WSL.
 
+Installing WSL distor second time
+=================================
+
+Microsoft provides certain Linux distros out of the box::
+
+  wsl --list --online
+  NAME            FRIENDLY NAME
+  Ubuntu          Ubuntu
+  Debian          Debian GNU/Linux
+  kali-linux      Kali Linux Rolling
+  openSUSE-42     openSUSE Leap 42
+  SLES-12         SUSE Linux Enterprise Server v12
+  Ubuntu-16.04    Ubuntu 16.04 LTS
+  Ubuntu-18.04    Ubuntu 18.04 LTS
+  Ubuntu-20.04    Ubuntu 20.04 LTS
+
+After the installation you will have an executable ``NAME.exe`` for convenient entering into
+distro, compare::
+
+  $ wsl -d NAME CMD
+  $ NAME.exe CMD
+
+You install such distros via::
+
+  wsl --install NAME
+
+What if you want 2 Debian distros? Unfortunately you have to deal with rootfs:
+
+* either export existing WSL distro::
+
+    wsl --export Alpine alpine.tar
+    wsl --import alpine-copy 'c:\srv\wsl\alpine-copy' alpine.tar
+
+* or use LXC / OCI rootfs (like one from https://alpinelinux.org/downloads/ or
+  http://cdimage.ubuntu.com/ubuntu-base/releases/)::
+
+    wget https://dl-cdn.alpinelinux.org/alpine/v3.16/releases/x86_64/alpine-minirootfs-3.16.0-x86_64.tar.gz
+    wsl --import alpine-x 'c:\srv\wsl\alpine-x' alpine-minirootfs-3.16.0-x86_64.tar.gz
+
+I'd suggest to use Ubuntu "base" images instead (less bloated than "cloud" images):
+
+* http://cdimage.ubuntu.com/ubuntu-base/releases - base images
+* https://cloud-images.ubuntu.com/releases/ - cloud images
+
+You download rootfs and import it::
+
+  wget http://cdimage.ubuntu.com/ubuntu-base/releases/22.04/release/ubuntu-base-22.04-base-amd64.tar.gz
+  wsl --import my-ubuntu c:\wsl\my-ubuntu ubuntu-base-22.04-base-amd64.tar.gz --version 2
