 ## Getting Started
 
-- Currently Wekan development is done mainly at Ubuntu 16.04 64bit, but building Wekan does work on any Debian 9 64bit or Ubuntu 14.04 64bit or newer.
-- Install [Wekan from source](https://github.com/wekan/wekan) with rebuild-wekan.sh script, with options 1 to install dependencies and 2 to rebuild source, to your Linux computer (Debian 9 or Ubuntu 14.04 or newer), or try installing it via the [[virtual appliance|virtual-appliance]]
-- You can use for example [Visual Studio Code](https://code.visualstudio.com/) for editing code, it has Meteor.js etc plugins 
-- When changing database schema, [migrations can be used](https://github.com/wekan/wekan/blob/master/server/migrations.js).
