Before going further, install inim with nimble:

$ nimble install -y inim

Also, make sure you have SQLite installed. On most Linux distributions, it should be preinstalled. To install SQLite in macOS, use brew. On Windows, use scoop. Should you want to follow this tutorial while using postgres, then please be aware that placeholders in postgres are not indicated with ?, but with $1, $2, $3... etc. instead.

Then, start a new inim session:

$ inim -d:normDebug
