Description: # `zeitgitter` — Independent `git` Timestamper
        
        ## Timestamping: Why?
        
        Being able to provide evidence that **you had some piece of information at a
        given time** and **it has not changed since** are important in many aspects of
        personal, academic, or corporate life.
        
        It can help provide evidence
        - that you had some idea already at a given time,
        - that you already had a piece of code, or
        - that you knew about a document at a given time.
        
        Timestamping does not assure *authorship* of the idea, code, or document. It
        only provides evidence to the *existence* at a given point in time. Depending
        on the context, authorship might be implied, at least weakly.
        
        ## `zeitgitter` for Timestamping
        
        `zeitgitter` consists of two components:
        
        1. A timestamping client, which can add a timestamp as a digital signature to
           an existing `git` repository. Existing `git` mechanisms can then be used
           to distribute these timestamps (stored in commits or tags) or keep them
           private.
        2. A timestamping server, which supports timestamping `git` repositories and
           stores its history of commits timestamped in a `git` repository as well.
           Anybody can operate such a timestamping server, but using an independent
           timestamper provides strongest evidence, as collusion is less likely.
           - Publication of the timestamps history; as well as
           - getting cross-timestamps of other independent timestampers on your
             timestamp history
           both provide mechanisms to assure that timestamping has not been done
           retroactively ("backstamping").
        
        The timestamping client is called `git timestamp` and allows to issue
        timestamped, signed tags or commits.
        
        To simplify deployment, we provide a free timestamping server at
        [https://gitta.zeitgitter.ch](https://gitta.zeitgitter.ch). It is able to provide several
        million timestamps per day. However, if you or your organization plan to issue
        more than a hundred timestamps per day, please consider installing and using
        your own timestamping server and have it being cross-timestamped with other
        servers.
        
        ## Setting up your own timestamping server
        
        Having your own timestamping server provides several benefits:
        
        * The number of timestamps you request, their commit ID, as well as
          the times at which they are stamped, remain you business alone.
        * You can request as many timestamps as you like.
        * If you like, you can provide a service to the community as well,
          by timestamping other servers in turn. This strengthens the
          overall trust of these timestamps.
        
        There are currently two options for installation:
        * [Running a Zeitgitter timestamper in Docker](docker/README.md) (recommended; only requires setting four variables)
        * [Traditional install on a Linux server](doc/Install.md) (more work)
