Documentation for secure use of BlockchainCommons cli tools #writing

This issue relies on #154.

This documentation should be added to: https://github.com/BlockchainCommons/Community/blob/master/secure-use-of-cli-tools.md.

---

- [ ] Document how to use each BlockchainCommons tool with:
- Secure operating systems:
- [x] TailsOS
- [ ] Qubes
- [ ] Whonix
- Make sure to specify:
- How does a user obtain and verify the integrity of a tool?
- How does a user install a tool in a running instance of the OS?
- How does a user create persistent storage and configuration for TailsOS so that the tools are automatically installed each time they boot the OS?
- [ ] Document use case cases and secure development docs for BlockchainCommons CLI Tools.
- Use #130 for reference.
