 Further, tuning the update frequently will decrease the traffic even more.
 
 
+
+Download & Install
+------------------
+
+Requires macOS Mojave (10.14) or higher.
+
+### Easy way
+Go to [releases](https://github.com/relikd/baRSS/releases) and downloaded the latest version.  
+Searching for the App Store release? Read this [notice](#app-store-notice).
+
+### Build from source
+You'll need Xcode, [RSXML2] \(required), and [QLOPML] \(optional).
+
+```sh
+git clone https://github.com/relikd/baRSS
+git clone https://github.com/relikd/RSXML2
+git clone https://github.com/relikd/QLOPML
+```
+
+Alternatively, you can simply delete the `QLOPML` project reference without much harm.
+`QLOPML` is a Quick Look plugin for `.opml` files.
+It will display the file contents whenever you hit spacebar.
+
+That's it. 
+Open `baRSS/baRSS.xcodeproj` and build the project. 
+Note, there are some compiler flags that append 'beta' to the development release. 
+If you prefer the optimized release version go to `Product > Archive`.
+
+
+
+Hidden options
+--------------
+
+### Launch on start / reboot
+
+baRSS has no option to launch it on start.
+However, you can still add the application to auto boot by adding it to the system login items:
+
+`System Preferences > User > Login Items` (macOS 10.x-12)
+`System Preferences > General > Login Items & Extensions` (macOS 13+)
+
+
+### UI options
+
+1. If you hold down the option key and click on an article item, you can mark a single item (un-)read without opening it.
+I am still searching for a way to keep the menu open after click (if you know of a way, let me know!).
+
+2. To add websites without RSS feed you can use the regex converter.
+Hold down the option key in the feed edit modal and click the red regex button.
+Though, admittedly, this is for experts only.
+I still have to find a nice user-friendly way to achieve this.
+
+3. The option “Show only unread” will hide all items which have been read.
+You can hold down option key before opening the menu bar icon to show hidden articles regardless.
+This is a nice way to quickly lookup a hidden article without going into settings and twiddling with the checkbox.
+
+
+### CLI options
+
+The following options have no UI equivalent and must be configured in Terminal. 
+Most likely, you will never stumble upon these if not reading this chapter.
+**Note:** To reset an option run `defaults delete de.relikd.baRSS {KEY}`, where `{KEY}` is an option from below.
+
+
+1. When holding down the option key, the menu will show an item to open only a few unread items at a time. 
+This number can be changed with the following Terminal command (default: 10):
+```
+defaults write de.relikd.baRSS openFewLinksLimit -int 10
+```
+
+2. In preferences you can choose to show 'Short article names'. 
+This will limit the number of displayed characters to 60 (default). 
+With this Terminal command you can customize this limit:
+```
+defaults write de.relikd.baRSS shortArticleNamesLimit -int 50
+```
+
+3. Limit the number of displayed articles per feed menu.
+**Note:** displayed unread count may be different than the unread items inside. 'Open all unread' will open hidden items too.
+```
+defaults write de.relikd.baRSS articlesInMenuLimit -int 40
+```
+
+4. You can change the appearance of colors throughout the application. 
+E.g., The tint color of the menu bar icon and the color of the blue unread articles dot.
+```
+defaults write de.relikd.baRSS colorStatusIconTint -string "#37F"
+defaults write de.relikd.baRSS colorUnreadIndicator -string "#FBA33A"
+```
+
+5. To backup your list of subscribed feeds, here is a one-liner:
+```
+open barss:backup && cp "$HOME/Library/Containers/de.relikd.baRSS/Data/Library/Application Support/baRSS/backup/feeds_latest.opml" "$HOME/Desktop/baRSS_backup_$(date "+%Y-%m-%d").opml"
+```

+If you find this app somewhere on the App Store, you can be sure that it is a counterfeit.
+As long as you can read this very notice, I am not responsible for the publication.
+Further, I can't guarantee the App Store version wasn't modified by a malicious actor to spy on you.

-This project uses a modified version of Brent Simmons [RSXML](https://github.com/brentsimmons/RSXML) for feed parsing. 
-RSXML is licensed under a MIT license (same as this project).

-
-Download & Install

-### Easy way
-Go to [releases](https://github.com/relikd/baRSS/releases) and downloaded the latest version.

-You'll need Xcode and [Carthage](https://github.com/Carthage/Carthage#installing-carthage). 
-The latter is optional, you can build the [RSXML2](https://github.com/relikd/RSXML2) library from source instead. 
-Carthage just makes it more convenient.
-Download and unzip this project, navigate to the root folder and run `carthage bootstrap --platform macOS`.

-Next, you need to clone [QLOPML](https://github.com/relikd/QLOPML) in the same folder where this project is.
