+title: The FreeSewing development environment
+order: 30
+---
+
+If you have been to FreeSewing.org the FreeSewing development environment will look familiar.
+That's because under the hood, it re-uses the same building blocks.
+
+At the top of the page is the header with a row of icons that lay out what is available to you.
+
+![The icons in the header of the FreeSewing development environment](./header.png)
+
+From left to right you can see:
+
+- **Home** will take you to the home page / welcome page
+- **Design** will offer you a list of templates to start a design from (more on this below)
+- **Documentation** will show a page with links to our documentation
+- **Code** will show a page with links to our source code
+- **Support** will show a page with the various ways you can get help
+- **Theme** allows you to change the theme (in other works the color scheme)
+- **Language** allows you to change the language
+- **Sign In** allows you to sign in to your FreeSewing account so you can use
+  your (and our) measurements sets while designing
+
+## Design templates
+
+If you click he **Design** icon it will show this menu:
+
+![Design templates provided by the FreeSewing development environment](./templates.png)
+
+It allows you to choose a desing template to start from. The following templates are included:
+
+- **From scratch**: Start with an (almost) empty design
+- **Tutorial**: Start with the end result of this very tutorial
+- **From Brian**: Start with a design that extends [Brian]('https://freesewing.org/designs/brian)
+- **From Bent**: Start with a design that extends [Bent]('https://freesewing.org/designs/bent)
+- **From Titan**: Start with a design that extends [Titan]('https://freesewing.org/designs/titan)
+- **From Bella**: Start with a design that extends [Bella]('https://freesewing.org/designs/bella)
+- **From Breanna**: Start with a design that extends [Breanna]('https://freesewing.org/designs/breanna)
+
+For the following along this tutorial, you have two options:
+
+- Pick **Tutorial** if you prefer to read along, make small changes, and see how they affect the design.
+- Pick **From scratch** if you prefer to actively participate be recreating the desing in this tutorial.
+
+I recommend the latter. You will learn (and remember) a lot more if you are activele engaging.
