-The export QR codes from authentication apps can be provided in three ways to this script:
+The exported QR codes from authentication apps can be read in three ways:
 
-1. Capture from the system camera in a GUI,
-2. Image files containing the QR codes, and
-3. Text files containing the QR code data generated by QR readers.
+1. Capture the QR codes with the system camera using a GUI, 🆕
+2. Read image files containing the QR codes, and 🆕
+3. Read text files containing the QR code data generated by third-party QR readers.
 
-The secret and otp values can be exported to json or csv files, as well as printed or saved to PNG images.

+## Download and run binary executable (🆕 since v2.1)
+
+1. Download executable for your platform from [latest release](https://github.com/scito/extract_otp_secrets/releases/latest), see assets
+2. Linux and macOS: Set executable bit for the downloaded file, e.g in terminal with `chmod +x extract_otp_secrets_X.Y.Z_OS_ARCH`
+3. Start executable by clicking or from command line (macOS: startable only from command line, see [below](#macos))
+
+:heavy_check_mark: Everything is just packed in one executable.  
+:heavy_check_mark: No installation needed, neither Python nor any dependencies have to be installed.  
+:heavy_check_mark: Easy and convenient  
+
+:information_source: There is a delay after starting the executable since the files have internally to be unpacked.
+
+:information_source: If you are a developer, you might prefer to run the Python script directly, see [Installation](#installation-of-python-script-recommended-for-developers-or-advanced-users)
+
+> :warning: Some antivirus tools may show a virus or trojan alert for the executable.
+> This alert is a false positive.
+> This is a known problem for executables generated by PyInstaller.
+> If you have any doubt, please use directly the [Python script](#installation-of-python-script-recommended-for-developers-or-advanced-users).
+
+:information_source: The executables are not signed. Thus, the operating system may show a warning about download from unknown source.
+
+### MacOS
+
+> Beginning in macOS 10.15, all software built after June 1, 2019, and distributed with Developer ID must be notarized. However, you aren’t required to notarize software that you distribute through the Mac App Store because the App Store submission process already includes equivalent security checks. <small>[developer.apple.com](https://developer.apple.com/documentation/security/notarizing_macos_software_before_distribution)</small>
+
+:x: Unfortunately, I cannot provide a signed and notarized installable application for macOS as .dmg or .pkg. Apple is not Open Source friendly and requires a yearly Developer ID subscription. I am not willing to pay [USD 99 per year](https://developer.apple.com/support/compare-memberships/) to Apple for this little open source tool.
+
+However, the bare executable can be executed from the command line:
+
+1. Download executable for macOS platform from [latest release](https://github.com/scito/extract_otp_secrets/releases/latest), see assets
+2. Open `Terminal` application
+3. Change to Downloads folder in Terminal: `cd $HOME/Downloads`
+4. Remove quarantine bit for the downloaded file: `xattr -r -d com.apple.quarantine extract_otp_secrets_X.Y.Z_macos_x86_64`
+5. Set executable bit for the downloaded file: `chmod +x extract_otp_secrets_X.Y.Z_macos_x86_64`
+6. Start executable from command line for the first time: `./extract_otp_secrets_X.Y.Z_macos_x86_64`
+7. Wait approximately 30 seconds to 1 minute on the first run. Terminal will display the following error:
+    ```
+    OpenCV: not authorized to capture video (status 0), requesting...
+    OpenCV: camera failed to properly initialize!
+    ```
+8. macOS will then prompt to request camera access.
+9. After allowing camera access, rerun the program.
+10. On the second run, the GUI prompt shows correctly and is fully operable: `./extract_otp_secrets_X.Y.Z_macos_x86_64`
+
+:information_source: Replace `X.Y.Z` in above commands with the version number of your downloaded file, e.g. `extract_otp_secrets_2.4.0_macos_x86_64`
+
+:information_source: If Rosetta2 emulation is installed, these steps work also for M1 and M2 Apple Silicon processors and the program can be executed directly.
+
+Tested with extract_otp_secrets_2.8.1_macos_x86_64 on macOS Sequoia 15.1 beta. Source: [#283](https://github.com/scito/extract_otp_secrets/issues/283)

+## Usage
+
+### Capture QR codes from camera (🆕 since version 2.0)
+
+1. Open "Google Authenticator" app on the mobile phone
+2. Export the QR codes from "Google Authenticator" app (see [how to export](#how-to-export-otp-secrets-from-google-authenticator-app))
+3. Point the exported QR codes to the camera of your computer
+4. Run the program without infile parameters:
 ```
+extract_otp_secrets
+```
+
+![CV2 Capture from camera screenshot](docs/cv2_capture_screenshot.png)
+
+Detected QR codes are surrounded with a frame. The color of the frame indicates the extracting result:
+
+* Green: The QR code is detected, decoded and the OTP secret was successfully extracted.
+* Red: The QR code is detected and decoded, but could not be successfully extracted. This is the case if a QR code not containing OTP data is captured.
+* Magenta: The QR code is detected, but could not be decoded. The QR code should be presented better to the camera or another QR reader could be used.
+
+Key commands:
+
+* Space: change QR code reader
+* C: save as csv file (🆕 since v2.2)
+* J: save as json file (🆕 since v2.2)
+* K: save as KeePass csv file (🆕 since v2.2)
+* ESC, ENTER, Q: quit the program
+
+The secrets are printed by default to the console. [Set program parameters](#program-help-arguments-and-options) for other types of output, e.g. `--csv exported_secrets.csv`.
+
+### With builtin QR decoder from image files (🆕 since version 2.0)
+

+4. Transfer the images files to the computer where his script is installed.
+5. Call this script with the file as input:
+```

+```
+6. Remove unencrypted files with secrets from your computer and mobile.
+
+### With external QR decoder app from text files
+
+1. Open "Google Authenticator" app on the mobile phone
+2. Export the QR codes from "Google Authenticator" app (see [how to export](#how-to-export-otp-secrets-from-google-authenticator-app))
+3. Read QR codes with a third-party QR code reader (e.g. from another phone)
+4. Save the captured QR codes from the QR code reader to a text file, e.g. example_export.txt. Save each QR code on a new line. (The captured QR codes look like `otpauth-migration://offline?data=…`)
+5. Transfer the file to the computer where his script is installed.

 For reading QR codes with `ZBAR` QR reader, the zbar library must be installed.

-## Technical background
+## How to export otp secrets from Google Authenticator app
 
-The export QR code of "Google Authenticator" contains the URL `otpauth-migration://offline?data=...`.
-The data parameter is a base64 encoded proto3 message (Google Protocol Buffers).
-
-Command for regeneration of Python code from proto3 message definition file (only necessary in case of changes of the proto3 message definition or new protobuf versions):
-
-    protoc --plugin=protoc-gen-mypy=path/to/protoc-gen-mypy --python_out=src/protobuf_generated_python --mypy_out=src/protobuf_generated_python src/google_auth.proto
-
-The generated protobuf Python code was generated by protoc 21.12 (https://github.com/protocolbuffers/protobuf/releases/tag/v21.12).
-
-For Python type hint generation the [mypy-protobuf](https://github.com/nipunn1313/mypy-protobuf) package is used.
