-==== Computer memory ====
+==== The basics before starting ====
-FIXME
+Once you have verified that your Windows is recent enough, you should also:
+  * Install the [[other:win10apps#windows_terminal|Windows terminal]], because it will be one of the ways to open ''Ubuntu'' terminals, once ''Ubuntu'' is installed
+  * Have at least some basic knowledge of Linux...
+    * Get some [[other:newppl:starting#useful_documentation_for_beginners|basic Linux documentation]] if required
+==== Computer CPU and memory ====
+Contrary to other virtual machines, WSL is well integrated with the Windows operating system and the hardware drivers and has a very low default CPU and memory footprint!
+  * You should be able to play with WSL even with 8 Gb of RAM, but 16 Gb is recommended
+  * Of course, depending on what you need to do on your computer, a better processor will always help
+  * WSL+Ubuntu will use more CPU and RAM if you use it for running CPU and/or memory intensive processes! As would be the case with any Windows application... :-)
