# go-sh-manymanuals > Work in progress... :bomb: The idea behind this software came from the [Permacomputing Update 2021](http://viznut.fi/texts-en/permacomputing_update_2021.html), especially "Chapter 7. A collapse-tolerant business" which is a series of practical guidelines. One of which reads as follows: > Self-host everything you need for software work on local physical servers. > This includes all networked applications as well as an extensive library of > software and documentation (including repair manuals and OS distributions for > all relevant hardware). Offer hosting services to make use of the surplus. Which lead us to think about an application where one can upload and download manuals and datasheets for everything in [Varia](https://varia.zone). ## Hacking ``` mkdir -p datasheets # fill with https://vvvvvvaria.org/~crunk/datasheets.zip go run goshmm.go ```
