When user's create a new project it will be initialized with a template. This is stored in .Defaults/default-home/*.

These will use a {{handlebar}} syntax to describe the fields that will be initialized with the new project's name and author.

Here you will find three files:

• {{PROJ}}.t3ui
• {{PROJ}}.t3
• {{PROJ}}.cs

1. Create a new project called MyNewProject.
2. Update the project's home with your new content.
3. Save and exit TiXL editor.
4. Copy the .t3, .t3ui, and .cs files from your project's folder (e.g. C:/Users/YourName/Documents/TiXl/MyNewProject) to .Defaults/default-home/ in your tixl source code folder.
5. Rename the files (e.g. MyNewProject.t3 -> {{PROJ}}.t3, replacing the original once.
6. Open all three files (or the folder) in a text editor like Visual Studio Code.
7. Replace the Id, user name, project name and namespace as follows....

using T3.Core.Operator;
using T3.Core.Operator.Attributes;
using System.Runtime.InteropServices;
using T3.Core.DataTypes;
using T3.Core.Operator.Interfaces;
using T3.Core.Operator.Slots;
using T3.Core.Resource;

namespace {{NAMESPACE}};

[Guid("{{GUID}}")]
internal sealed class {{PROJ}} : Instance<{{PROJ}}>
{
}

{
  "Name": "{{PROJ}}",
  "Id": "{{GUID}}",

{
  "Id": "{{GUID}}"/*{{PROJ}}*/,
  "Description": "{{USER}}'s workspace for {{PROJ}}.",
  "InputUis": [],
  "SymbolChildUis": [
