# SIGit Documentation SIGit is an open source, encrypted document signing tool. Users can Create, Sign and Verify documents individually or in groups. ## Kind Numbers The baseline for our kind numbers is 1603 - because [BIP-39 word 1603](https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt#L1603) is "SIGN". Kind numbers therefore as follows: - 160300 - Create event - 160301 - Keys event - 1603 - Sign event
