All Nostr protocol documentation is maintained in the NIPs (Nostr Implementation Possibilities) repository. To access this information:
Reading Individual NIPs
Individual NIPs can be fetched from:
```
https://github.com/nostr-protocol/nips/blob/master/{NIP}.md
```
For example, NIP-01 (the basic protocol specification) is available at:
```
https://github.com/nostr-protocol/nips/blob/master/01.md
```
Finding Event Kinds
Documentation for Nostr event kinds is spread across one or more NIPs. There is no direct relationship between the NIP number and the kind number.
To find which NIPs document a specific event kind:
- First, fetch the README:
```
https://github.com/nostr-protocol/nips/blob/master/README.md
```
- Reference the "Event Kinds" table in the README to find which NIP(s) document the kind you're looking for
Discovering Existing Capabilities
The README should be consulted to:
- View the list of NIPs - Use this to discover what capabilities already exist on the Nostr network
- Review client and relay messages - Understand the communication protocol
- Check the list of tags - See what standardized tags are available
- Decide on using existing NIPs - Before implementing a feature, check if an existing NIP already covers it
Best Practices
Always start by fetching and reviewing the README to understand the current state of the protocol and avoid reinventing existing functionality.
