📦 Installation (all editors)

Compatible with VS Code ≥ 1.50, and all Cursor/Windsurf versions.
Cursor & Windsurf read directly from the VS Code Marketplace, so a single listing covers all three.

1 · Marketplace (recommended)

For easiest installation of the theme, you can access it directly from the VS Code Marketplace.

Or, from inside your favorite editor, do the following:

1. Press ⌘ Shift X / Ctrl Shift X.
2. Search for “Fusion Health” (identifier connorengland.fusion-health) and click Install.
3. Press ⌘ K T (or Ctrl K T) → pick Fusion Dark or Fusion Light.

2 · VSIX sideload

After cloning the repository, navigate to the root directory of the project. The VSIX file should be in the project's root or release directory.

Windows Note: On Windows, VSIX sideloading is the recommended method as manual folder copying does not work reliably. Extensions are automatically unpacked to %APPDATA%\{Editor}\extensions\ after installation.

For macOS/Linux:

# one file installs on every editor
VSIX=path/to/fusion-health-1.1.1.vsix  # Update path as needed
code     --install-extension "$VSIX"   # VS Code
cursor   --install-extension "$VSIX"   # Cursor
windsurf --install-extension "$VSIX"   # Windsurf

For Windows Command Prompt:

:: Use full path with quotes to handle spaces properly
code     --install-extension "C:\path\to\fusion-health-1.1.1.vsix"   
cursor   --install-extension "C:\path\to\fusion-health-1.1.1.vsix"   
windsurf --install-extension "C:\path\to\fusion-health-1.1.1.vsix"   

For Windows PowerShell:

# IMPORTANT: Use single quotes when setting variable, double quotes when using it
$VSIX = 'C:\path\to\fusion-health-1.1.1.vsix'  # Single quotes for assignment
code     --install-extension "$VSIX"   # Double quotes around variable
cursor   --install-extension "$VSIX"   # Double quotes around variable  
windsurf --install-extension "$VSIX"   # Double quotes around variable

Verify installation:

# Check if extension was installed successfully
windsurf --list-extensions | Select-String fusion

3 · Manual folder copy (macOS/Linux only)

Important: Manual folder copying only works reliably on macOS and Linux. Windows users should use VSIX sideloading instead (see method #2 above).

Drop the extension folder into the editor's extensions directory. After cloning the repository, use these commands:

# VS Code on macOS/Linux
cp -r /path/to/fusion_tools/themes/editors/vscode ~/.vscode/extensions/connorengland.fusion-health-1.1.1

# Cursor on macOS/Linux
cp -r /path/to/fusion_tools/themes/editors/vscode ~/.cursor/extensions/connorengland.fusion-health-1.1.1

# Windsurf on macOS/Linux
cp -r /path/to/fusion_tools/themes/editors/vscode ~/.windsurf/extensions/connorengland.fusion-health-1.1.1

Restart the editor → ⌘K T / CtrlK T → select Fusion Dark or Fusion Light.
