+# Move Tab to Next Window browser extension
+
+A browser extension which adds a tab context menu item (Firefox) and a button action (Firefox & Chrome) to move a tab to the next window.
+
+## Quick feature list
+
+- the initial tab position is remembered in the initial window, so if it's moved back to it, it moves into its original position
+- if the tab is active, it will become active in the new window
+- if the tab is inactive, it will stay inactive in the new window
+- if there is only 1 window, a new window will be opened on move
+
+## Technologies used
+
+- TypeScript in strict mode for safety
+- Parcel to build, transpile and hot-reload ts changes
+- `webextension-polyfill` for compatibility with both Firefox and Chrome
+- ESLint for linting
+
+## Contributions are welcome
+
+Prerequisites:
+
+- Node and NPM
+- VS Code (recommended)
+
+How to contribute:
+
+- fork the project
+- `npm run dev-ff` or `npm run dev-chrome`, load unpacked extension from `dist` directory. Hot reload for changes in TypeScript is enabled.
+- make changes, open a PR
