derives its core structure of items from a standard called GEDCOM. However, Gramps extends this standard where it has been deemed necessary. If you plan on using your family data with another system which uses GEDCOM, then you probably will want to try to restrict your use of features that are Gramps -only extensions. On the other hand, if you are not limited by other genealogical software, then you can enter your data in whatever ways make sense to you.
You can read more details about this issue in the section on [[Gramps and GEDCOM]].

The best way to learn Gramps is by working with your data. Let's get started!
The way you start Gramps depends on the operating system you are using.
As well as starting Gramps using the normal graphical user interface (GUI) as described below, it is also possible to start Gramps using a command line interface (CLI). CLI use can produce reports that are not available via the GUI, it can be used to create reports, do conversions etc. without opening a window, and can provide [[Gramps_5.1_Wiki_Manual_-_Error_and_Warning_Reference# Seeing_all_the_error_messages| extra information]] in the event of problems. For more information, see [[Gramps 5.1 Wiki Manual - Command Line| the Command Line appendix]].
=== Linux ===
Only the Linux platform is officially supported as Gramps developers use and test the source code on that platform, fixing any problems that arise due to upgrades.
Assuming you have used the standard Package Manager (either through a CLI or a GUI) for your Linux distribution, you will start Gramps in the normal way for your distribution. For example in Ubuntu 18.04, an icon is placed in the launcher, or the program can be started from Dash. For other distributions, an entry may be created in the Application menu (normally in the '''Office''' section).
