The current documentation (lets call now v2.0-rc1 still document assuming someone to use this repository as a git project. On the #24, the main comment #24 (comment) necessay means that in some cases, some operations should be done on somewhat isolated ambient. And a Tails, even if the user do have Persistent storage on same pen drive, is likely that is the perfect place to not enable.
So this issue is about do some basic documentation about be able to run at least the bin/ from persistence not enabled. This also is different from official tails documentation because our focus here is do some kung-fu scripting without GUIs.
