-# What is this?
+# Gantt chart
 
-Original WeKan is MIT-licensed software.
+This new Gantt feature was added to MIT WeKan 2025-12-22 at https://github.com/wekan/wekan
 
-This different Gantt version here currently uses Gantt chart component that has GPL license, so this Wekan Gantt version is GPL licensed.
+At "All Boards" page, click board to open one board view. There, Gantt is at top dropdown menu Swimlanes/Lists/Calendar/Gantt.
 
-Sometime later if that GPL licensed Gantt chart component will be changed to MIT licensed one, then that original MIT-licensed WeKan will get Gantt feature, and maybe this GPL version will be discontinued.
+Gantt shows all dates, according to selected date format at opened card: Received Start Due End.
 
-# How to use
+Gantt dates are shown for every week where exist dates at the current opened board.
 
-[Source](https://github.com/wekan/wekan/issues/2870#issuecomment-721690105)
+You can click task name to open card.
 
-At cards, both Start and End dates should be set (not Due date) for the tasks to be displayed.
+You can click any date icon to change that date, like: Received Start Due End.
 
-# Funding for more features?
+# Old WeKan Gantt GPL
 
-You can fund development of more features of Gantt at https://wekan.fi/commercial-support, like for example:
-- more of day/week/month/year views
-- drag etc

-## How to install Snap
-
-[Like Snap install](https://github.com/wekan/wekan-snap/wiki/Install) but with commands like:
-```
-sudo snap install wekan-gantt-gpl
-
-sudo snap set wekan-gantt-gpl root-url='http://localhost'
-
-sudo snap set wekan-gantt-gpl port='80'
-```
-Stopping all:
-```
-sudo snap stop wekan-gantt-gpl
-```
-Stopping only some part:
-```
-sudo snap stop wekan-gantt-gpl.caddy
-
-sudo snap stop wekan-gantt-gpl.mongodb
-
-sudo snap stop wekan-gantt-gpl.wekan
-```
-
-## Changing from Wekan to Wekan Gantt GPL
-
-1) Install newest MongoDB to have also mongorestore available
-
-2) Backup database and settings:
-```
-sudo snap stop wekan.wekan
-
-mongodump --port 27019
-
-snap get wekan > snap-set.sh
-
-sudo snap remove wekan
-
-sudo snap install wekan-gantt-gpl
-
-sudo snap stop wekan-gantt-gpl.wekan
-
-nano snap-set.sh
-```
-Then edit that textfile so all commands will be similar to this:
-```
-sudo snap set wekan-gantt-gpl root-url='https://example.com'
-```
-And run settings:
-```
-chmod +x snap-set.sh
-
-./snap-set.sh
-
-sudo snap start wekan-gantt-gpl.wekan
-```
