-# Ollama App
+# Ollama for macOS and Windows
 
-## Linux
+## Download
 
-TODO
+- [macOS](https://github.com/ollama/app/releases/download/latest/Ollama.dmg)
+- [Windows](https://github.com/ollama/app/releases/download/latest/OllamaSetup.exe)
 
-## MacOS
+## Development
 
-TODO
+### Desktop App
 
-## Windows
+```bash
+go generate ./... &&
+go run ./cmd/app
+```
+
+### UI Development
+
+#### Setup
+
+Install required tools:
+
+```bash
+go install github.com/tkrajina/typescriptify-golang-structs/tscriptify@latest
+```
+
+#### Develop UI (Development Mode)
+
+1. Start the React development server (with hot-reload):
+
+```bash
+cd ui/app
+npm install
+npm run dev
+```
+
+2. In a separate terminal, run the Ollama app with the `-dev` flag:
+
+```bash
+go generate ./... &&
+OLLAMA_DEBUG=1 go run ./cmd/app -dev
+```
+
+The `-dev` flag enables:
+
+- Loading the UI from the Vite dev server at http://localhost:5173
+- Fixed UI server port at http://127.0.0.1:3001 for API requests
+- CORS headers for cross-origin requests
+- Hot-reload support for UI development
+
+## Build
+
+
+### Windows
 
-If you want to build the installer, youll need to install
 - https://jrsoftware.org/isinfo.php
 
 
-In the top directory of this repo, run the following powershell script
-to build the ollama CLI, ollama app, and ollama installer.
-
+**Dependencies** - either build a local copy of ollama, or use a github release
 ```powershell
-powershell -ExecutionPolicy Bypass -File .\scripts\build_windows.ps1
+# Local dependencies
+.\scripts\deps_local.ps1
+
+# Release dependencies
+.\scripts\deps_release.ps1 0.6.8
+```
+
+**Build**
+```powershell
+.\scripts\build_windows.ps1
+```
+
+### macOS
+
+CI builds with Xcode 14.1 for OS compatibility prior to v13.  If you want to manually build v11+ support, you can download the older Xcode [here](https://developer.apple.com/services-account/download?path=/Developer_Tools/Xcode_14.1/Xcode_14.1.xip), extract, then `mv ./Xcode.app /Applications/Xcode_14.1.0.app` then activate with:
+
+```
+export CGO_CFLAGS=-mmacosx-version-min=12.0
+export CGO_CXXFLAGS=-mmacosx-version-min=12.0
+export CGO_LDFLAGS=-mmacosx-version-min=12.0

+export DEVELOPER_DIR=/Applications/Xcode_14.1.0.app/Contents/Developer
+```
+

+The Browser tool provides web browsing capability for gpt-oss.

+The tool optionally may open a URL directly - especially if one is passed in.
+
+Each action is saved into an append-only page stack `responses.BrowserStateData` to keep

+browser state representation between the tool, ui, and db.
