+# How to release
 
-## Steps that needs to be done to release new version
+Consumers integrate this fork through the Swift Package Manager and pin a tag, so a
+release is a tag plus a GitHub release — there are no artifacts to build or upload.
 
-- add new change log to `Changelog.md`
-- change `RxBluetoothKit.podspec` with new library version
-- generate new doc by running script `./scripts/generate-docs.sh x.x.x`
-- create archive by running `carthage build --no-skip-current && carthage archive RxBluetoothKit`
-- create new Pull Request with that changes and merge it
-- create new release on github and add archive previously created
-- add library to cocoapods trunk by running: `pod trunk push RxBluetoothKit.podspec`
+1. Add a section for the new version at the top of [CHANGELOG.md](CHANGELOG.md).
+2. Open a pull request with that change and merge it once the build workflow is green.
+3. Tag the merge commit with the bare version number — `6.4.0`, not `v6.4.0`, to match
+   the existing tags — and push the tag.
+4. Create a GitHub release from that tag, using the changelog section as its notes.
+
+Raising the required RxSwift range breaks anyone pinned to an older RxSwift: the manifest
+allows one minor at a time, and Swift Package Manager resolves a single RxSwift across the
+whole consumer graph, so both cannot be satisfied. Decide the version number with that in
+mind rather than by habit, and say so in the changelog.

 RxBluetoothKit is a Bluetooth library that makes interaction with BLE devices much more pleasant. It's backed by RxSwift and CoreBluetooth and it provides nice API, for both Central and Peripheral modes. All to work with and make your code more readable, reliable and easier to maintain. 
 
 Here is a sneak peek of what you can do with RxBluetoothKit:

 # Installation
 
-## CocoaPods
-[CocoaPods](http://cocoapods.org) is a dependency manager for CocoaProjects.
-To integrate RxBluetoothKit into your Xcode project using CocoaPods specify it in your `Podfile`:
-```ruby
-pod 'RxBluetoothKit_Airthings'
-```
-Then, run the following command:
-`$ pod install`
-
-## Carthage
-
-#### FYI: Carthage has some issues with Xcode 12 or later. Therefore it is not supported properly. Always welcome developers to fix it.
-
-~[Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.
-To integrate RxBluetoothKit into your Xcode project using Carthage  specify it in your `Cartfile`:~
-```swift
-github "Polidea/RxBluetoothKit"
-```
-~Then, run `carthage update` to build framework and drag `RxBluetoothKit.framework` into your Xcode project.~
-
 ## Swift Package Manager
 
 Versions >= 4.0 of the library integrate with the Swift Package Manager. In order to do that please specify our project as one of your dependencies in `Package.swift` file.
