\n\n# Installation\n\n### Global installation (works anywhere)\n\n1. Run `npm install -g mtslack` in a terminal (or run `sudo npx mtslack` if you don't want to install it globally)\n2. Run the command `sudo mtslack` (in Windows, you need to open the Terminal in Administrator Mode)\n3. You will be prompted with a menu with two options:\n - Apply Theme\n - Remove Theme\n\n4. Select *Apply Theme* to apply the theme.\n5. Open or Restart (with Cmd-Q) Slack\n6. ?????\n7. PROFIT!!!!!!!\n\n### Revert to the default theme\n\nThe best way to revert to the default theme would be to use the backup copy you made and overwrite the patched Slack.app\n\nThere is also a `Remove Theme` option in the menu but it is less robust.\n\n### Updates\n\n`mtslack` has an auto-update function. Whenever there is a new package available, a notification will appear on the\nbottom on your Slack Window prompting you to run the `mtslack` command again to trigger the update. You will then need\nto run the command again to apply the updates.\n\n----\n\n### Slack Tweaks\n\nSince version 2.0 you can also profit from a bunch of **Slack Tweaks** to make the application more enjoyable. You can\nfind a button to open the Slack Tweaks on the channels sidebar.\n\n#### Slack Tweak Control Panel\n\n\n\nThis panel controls which tweak toggles are available. **This doesn't actually toggle the tweaks themselves!**.\n\nOnce you've enabled a tweak, a new toggle button will appear on the Channel Header. Pressing on these buttons will\nactivate the tweak.\n\nYou can also activate the toggle using a shortcut.\n\n\n\nThese settings are saved in the application's Local Storage.\n\n#### Highlight Code [NEW!] (Ctrl+Alt+H)\n\nAutomatically detects code blocks and highlight then using highlight.js. You can annotate the code blocks by setting the\nlanguage name as the first line.\n\nExample: to annotate the code as a javascript code, write:\n\n```\njavascript\nfunction foo() {\n}\n```\n\n#### Modal Overlays (Ctrl+Alt+O)\n\nThis button will toggle an overlay to display whenever settings are open.\n\n#### Dim Absent People (Ctrl+Alt+D)\n\nThis button will dim absent people from the sidebar, making the present ones more prominent.\n\n#### Loop Over selected themes (Ctrl+Alt+T)\n\nThis button will loop over the available themes, allowing you to choose a theme in realtime.\n\n#### Toggle Custom Font (Ctrl+Alt+F)\n\nSwitch the fonts used in the app with the font you've defined in the Slack Tweak Settings.\n\n#### Toggle Custom Monospace Font (Ctrl+Alt+M)\n\nSwitch the monospace font size and family used in the app with the font you've defined in the Slack Tweak Settings.\n\n#### Accent Color (Ctrl+Alt+A)\n\nSwitch the current theme's accent color with the one of your choice. You can set the desired color in the Slack Tweak\nSettings.\n\n#### Links Color (Ctrl+Alt+L)\n\nSwitch the current theme's links color with the one of your choice. You can set the desired color in the Slack Tweak\nSettings.\n\n### Important Note!\n\nPlease note that these tweaks rely on modifying the app realtime. There's a high chance further updates from Slack would\nbreak those tweaks. In this case please report to the repository, thanks!\n\n----\n\n# Development\n\n## Building styles\n\nThis project consists in two parts:\n\n- The CLI, used for applying the styles\n- The Styles, written with Sass (Node-sass)\n\nThe cli is found in the `lib` directory while the styles are found in the `styles` directory.\n\nThen run `npm run styles` or `npm run debugStyles` to compile the scss files in `dist/slack.min.css` or `dist/slack.css`\n\n## Apply the styles\n\n### Using the WebApp\n\nOpen Slack on the browser.
