+Code packages
+=============
+
+This NIP handles distribution of code packages (akin to npm packages) in a decentralized way. 
+
+Code package consists of a list of files in directories. A code package event of kind `1036` contains a list of hashes of files along with their relative paths, directories are not listed. File contents are to be stored on Blossom or NIP-96 or other kinds of servers that use `sha256` for addressing.
+
+The `content` field of the code package may contain human readable description of the package contents. Each file is an `f` tag containing sha256 file hash, relative file path within the package and a URL to download the file content. Other recommended meta tags are given as example below.
+
+Code package also contains `x` tag - the `package hash`, which is a combined hash of included relative paths and file hashes. This `package hash` serves as a content-based package address, to allow apps to fetch packages with the same package hash. Events referring to code package events should use package event id with a relay hint, and may include package hash in the reference - if original event is not accessible, package hash can be searched on relays as a fallback.
+
+Example package event:

+Pseudo-code to calculate package hash:
+```
+  const pkg: { 
+    hash: string, // hex hash of a file
+    path: string  // relative file path w/o leading /
+  }[] = [...];
+  pkg.sort((a, b) => (a.hash > b.hash ? 1 : a.hash === b.hash ? 0 : -1));
+  const packageHash = bytesToHex(
+    sha256(pkg.map((e) => e.hash + e.entry).join(","))
+  );
+```
+
+Test vector for a package hash:
+```
