 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 is "SIGN".
+
+Kind numbers therefore as follows:
+
+ - 160300 - Create
+ - 160301 - Keys event
+
+ - 1603 - Sign

+
+## Flow
+ 
+  - Create Event
+  - Sign Event
+  - COMPLETE EVENT
+
+---
+
+sigit is made up of:
+
+ - pointers, notifications, components (events) 
+ - files (encrypted blobs)
+ - all events are private (giftwrapped)
+
+
+
+
+## Create Event Component - kind X1
+
+Signer should display:  
+```
+You are signing an Agreement template for the following npubs:
+- npub1
+- npub2
+
+Ensure this event is sourced from a trusted SIGit instance.
+```
+
+- Signed by Creator
+- NOT published by default
+- fileData{}
+- counterpartyData{}
+- markData{}
+
+This data is all stored inside the X1 blob
+Verifications take place on all the elements in X2 (todo: list them)
+
+
+
+---
+
+##  File pointer 
+
+Signer should say:  "You are verifying that the following files exist:"
+
+And list the full urls (blossom url + hash)
+
+ - signed by sender
+ - NOT PUBLISHED by default
+ - points to encrypted blossom blob (BB)
+
+```json
+{"content":"",
+ "kind": XX, --tbd
+ "tags"[ 
+   
+   ["filehash","$(hash)"],
+   ["blossomUrls","url1","blossom2"], --optional
+   ["engine": "SIGIT"]
+ ] 
+}
+```
+

+
+## Encrypted Blob from XX
+
+Contains:
+ - Create Event 
+ - Files

 # Create
+
+## Nostr Event
+
+This event is designed to provide clarity (when signing) about the agreement being created. It is NOT published to a relay (instead, it is saved in an encrypted zip).
+
+```json
+{ 
+  "kind": 160300,
+  "content": "You are signing an Agreement Template for the following npubs:\n- npub1\n- npub2\n\nEnsure this event is sourced from a trusted SIGit instance.",
+  "created_at": 1716564780,
+  "id": "...",
+  "sig": "...",
+  "pubkey": "pubkey of CREATOR",
+  "tags":[
+    ["signers","npub1d0csynr..","npub1nqulz.."],
+    ["viewers","npub1viewer1"], // optional tag, only if there are viewers
+    ["files","hash1:name1.csv","hash2:name2.pdf"], // extension determines the file type.  Order determines index.
+    ["meta","hash1"] // the hash of the meta.json file
+  ]
+}
+```
+
+## Metadata JSON
+
+This contains the marks that should be applied to the files
+
+## Encrypted Zip File
+
+This file contains the following:
+
+- "files" folder - the unmarked files, using original filenames (to make them easy to open)
+- "events" folder - contains the create Event and OTS request event
+- meta.json file - contains the marks information
+
+## Keys 
+
+The keys.json looks like this:
+
+```json
+{ 
+  "kind": 160301,
+  "content": "",
+  "created_at": 1716564780,
+  "id": "...",
+  "sig": "",  
+  "pubkey": "random pubkey",
+  "tags":[
+    ["filehash",<optional list of blossom servers>],
+    ["array of decryption keys", "encrypted to each recipient"]
+  ]
+}
+```
+
+
+
+## Online Communication
+
+Once the zip file is created, encrypted, and uploaded to the blossom server(s) - the decryption key and file location(s) must be sent to each counterparty.  This is done using a regular NIP-17 Chat Message.
+
+The rumor would be the same for all recipients:
+
+```json
+{
+  "id": "<usual hash>",
+  "pubkey": "<sender-pubkey>",
+  "created_at": "<current-time>",
+  "kind": 14,
+  "tags": [
+    ["p", "<receiver-1-pubkey>", "<relay-url>"],
+    ["p", "<receiver-2-pubkey>", "<relay-url>"],
+    ["e", "<kind-14-id>", "<relay-url>", "reply"] // if this is a reply
+    ["subject", "<conversation-title>"],
+    // by including tags from the kind 160301 we avoid an additional lookup in SIGit
+    ["filehash",<optional list of blossom servers>],
+    ["array of decryption keys", "encrypted to each recipient"]
+  ],
+  "content": "A new SIGit has been created - please visit your preferred instance or click https://sigit.io/find/$(idOfKind160301)",
+}
+```
+
+## Online Flow
+
+* Create & sign kind 160300
+* Zip this along with files and meta.json
+* Push zip to blossom
+* Publish kind 160301 with decryption keys
+* Send DM with link to above (manual flow) and keys (automatic flow)
