+NUÑO's STUPID NODE VERSION MANAGER
+==================================
+
+## About
+
+The problem: Current node version managers, such as [nvm](https://github.com/nvm-sh/nvm) or [asdf](https://asdf-vm.com/) are too slow. In particular, they add half a second to a few seconds when loaded with bash.
+
+The solution: Write a stupidly simple node version manager which is significantly simpler, hackier, less featureful, and less secure, but much faster. 
+
+Use this software at your own risk. In particular, consider reading the source code.
+
+## Usage
+
+Read the `nsnvm.sh` file, then execute it like:
+
+```
+./nsvnm.sh 18.12.1
+```
+
+Make sure that you pass it one argument and that it is a correct node version number: there is no error checking.
