5. HISTORY
What was Git designed for?
• Take Concurrent Versions System (CVS) as an example of what not to do; if in doubt,
make the exact opposite decision
• Support a distributed workflow
• Very strong safeguards against corruption, either accidental or malicious
6. HISTORY
• Development began on 3 April 2015
• The first version of git was just ~1300 lines of code
• The project was announced on 6 April and became self-hosting as of 7 April
• The first merge of multiple branches was done on 18 April.
• On 29 April, the nascent Git was benchmarked recording patches to the Linux kernel
tree at the rate of 6.7 per second.
• On 16 June Git managed the kernel 2.6.12 release.
• Torvalds turned over maintenance on 26 July 2005 to Junio Hamano
• Hamano was responsible for the 1.0 release on 21 December 2005, and remains the
project's maintainer.

13. WHAT IS GIT
• Allows users to work productively when not connected to a network.
• Makes most operations much faster.
• Allows private work, so users can use their changes even for early drafts they do
not want to publish.
• Avoids relying on one physical machine as a single point of failure.
