 This is a list of projects that (as far as we can tell so far) follow free software principles and do something interesting or useful in terms of 1) doing basic computer functions on a UNIX system; 2) making basic computer tasks easier to do or teaching people about UNIX; 3) cryptography: or onboarding people to cryptography and privacy best practices for personal communications; or 4) decentralization: peer-to-peer infrastructure or 5) GUIs for helping people to self-organize politically or organize themselves or their community's information in a post-colonial way; 6) self-host content in an increasingly integrated way; or 7) form ad-hoc mesh networks.
 
-The first projects that will be integrated are: tor, bitcoin, lightning, and SimpleX (in that order). After that, the next features and tools added to the suite will be chosen by popular demand, in close collaboration with specific partner communities.

After that, the next features and tools added to the suite will be chosen by popular demand, in close collaboration with specific partner communities. This list is similar to [awesome-free-software](https://github.com/johnjago/awesome-free-software) or [awesome-selfhosted](https://github.com/awesome-selfhosted/awesome-selfhosted#note-taking-and-editors) but more selective and integrated into a whole vision of a free software suite.
 
 We are very open to new suggests or critiques or existing items on this list. This is just a public place to collect research on the best free software and non-commercial open-source projects, so that they can be integrated into the ao-bash suite for easy, replicable installation and use by an increasingly large user base.
