 ## How does it work?
@ -36,17 +32,10 @@ We attempt multiple pathways:
 1. The presence of a `electron.asar` file denotes an electron version `<v7.0.0`, since later releases dropped that file and embedded it in the binary instead.
 2. A `version` text file is sometimes included in the final binary.
 3. The `node_modules/electron/package.json` file is sometimes present.
-4. A lookup table of [hashes from various electron releases](https://github.com/captn3m0/electron-fingerprints/) is used to guess the version. In case of multiple matches, it returns a range of versions.
+4. A lookup table of [hashes from various electron releases](https://github.com/captn3m0/electron-fingerprints/) is used to guess the version. (WIP)
 5. Get the electron version from the electron binary (WIP)

-Note that this can be run against untrusted binaries as it does not _try to run the application_. It has been tested against various file formats: zip/dmg/exe/AppImage/tar.gz etc. It extracts limited files using 7-zip to a temporary directory at runtime if needed.
-
-## Known Issues
-
-It is known to not work against:
-
-1. Windows setup files (ones with `-setup` in their name)
-2. On systems without 7-zip installed, it falls back to an older version of 7zip via the 7z-bin package on NPM. Unfortunately, the older version can't extract AppImage files correctly.
