## Introduction

Create and send Appointment-Confirmation-Message from Android-Calendar-Entry.

![](https://github.com/k3b/calef/raw/master/app/src/debug/res/drawable/calef_schema.png)

Making an appointment means

* Add date, time and title of the appointment to the Android-Calendar

* In Android-Calendar-Detailview use Send/Share (from menu or toolbar)

* Select "CalEF" as share destination (to convert to human readable text)

* Select the final Send/Share destination (clipboard, sms, mail, ...)

Usually calendar entries are shared in human-unreadable technical format "ICS" (or "VCS") that

calendar programs can read.

CalEF receives the technical format and re-sends/re-shares it-s content as human readable text.

Note: CalEF can also process "ics" (or "vcs") files (i.e. from a calendar backup).
