# 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: |Kind| Title|Signer|Storage| |---|---|---|---| |160300| Create event|creator|encrypted zip on blossom| |160301|Keys event|ephemeral key|Relay| |1603|Sign event| signer| encrypted zip on blossom |14|chat event|unsigned|gitwrap event| on relay
