Head to [sabre.io/baikal](https://sabre.io/baikal/) for information about installation, upgrading and troubleshooting. A German tutorial about installation of Baïkal, using it together with Thunderbird, Android and DavX5, sharing calendars, database maintenance and security can be found [here](https://github.com/JsBergbau/BaikalAnleitung). Its focus is for people with not so much IT experience. Therefore it is very detailed, step by step with a RaspberryPI used as server. With the same objective, a French guide, about installation on Debian, database maintenance, security and dealing with iOS clients can be found [here](https://github.com/criticalsool/Baikal-Guide-FR). Its focus is also for people with not so much IT experience. Upgrading --------- [](#upgrading) Please follow [the upgrade instructions](https://sabre.io/baikal/upgrade/). Credits ------- [](#credits) Baikal was created by [Jérôme Schneider](https://github.com/jeromeschneider) from Net Gusto and [fruux](https://fruux.com/) and is now developed by volunteers. Many thanks to Daniel Aleksandersen (@zcode) for greatly improving the quality of the project page. ### Health Score 61 — FairBetter than 99% of packages Maintenance73 Regular maintenance activity Popularity51 Moderate usage in the ecosystem Community37 Small or concentrated contributor base Maturity74 Established project with proven stability Bus Factor2 2 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
