+The following shell script should build python/vim assuming build requirements are met, just change the apt-get line to whatever your package manager uses. The DIR variable specifies install location for python & vim.
+
+IMPORTANT: To use these daily, make sure your `.bashrc` or other init file updates PATH so that $DIR/bin is on it. So for BASH, in your `.bashrc` append `export PATH=/usr/local/bin:$PATH`.

+```sh
+#!/usr/bin/env bash
