 (*) DESCRIPTION: `COMMAND`
 
+There are some non-oneliners. Not everything can be a oneliner.
+
+How to find binaries for the commands in your distro
+----------------------------------------------------
+
+You'll eventually get a 'command not found' message from your shell.
+You can try these commands to find the FILE (i.e. binaries) required to run some oneliners:
+
+    Arch-based distros: `pacman -Fy FILE`
+    Ubuntu-based distros: `apt-file update && apt-file find FILE`
+    RHEL / CentOS-based distros: `yum whatprovides '*FILE'`
+    Fedora: `dnf provides '*FILE'`
+    OpenSUSE: `zypper wp FILE`
+
+For Windows, it's a dog's breakfast. With enough effort, similar commands
+can be ran there with mixed results (you're on your own).
+
+You can try installing `Mingw-w64` to start. It uses a port of `pacman` for installing packages:
+	1. Open `Mingw-w64`
+	2. Run `pacman -Syu` in the terminal so upgrade all packages.
+	3. Repeat step 2 (closing and opening) until the commands reports "nothing to do".
+	4. Run `pacman -Fyu FILE` to find a package containing the FILE.
+
 TODO
 ----
 
-* More package manager commands (dpkg, apt, yum, etc.)
-* A longer TODO list
+* Keep moving commandlinefu dump to organized categories.
 
 Bonus
 -----
 
 You can alias a simple command like this one to get a nice menu that prints out the command:
 
     alias oneliner='print -z $(grep "^(\*)" oneliners.txt | fzf -e | grep -oP "(?<=: \`).*(?=\`$)")'
-    (requirements: zsh is your shell, GNU grep, fzf)
