Either note operating systems for which the README applies or add Windows specific commands

[MichaelHoltonPrice]

Windows requires a slightly different command to activate the environment:

.\palaeo\Scripts\activate

Also, it is sometimes necessary, especially if using Powershell, to first set execution policy scopes:

Set-ExecutionPolicy Unrestricted -Scope Process .\palaeo\Scripts\activate

I realize you may not want to support all operating systems (it can be a headache) and if so you might simply note so.
