 Kinds specify how clients should interpret the meaning of each event and the other fields of each event (e.g. an `"r"` tag may have a meaning in an event of kind 1 and an entirely different meaning in an event of kind 10002). Each NIP may define the meaning of a set of kinds that weren't defined elsewhere. This NIP defines two basic kinds:
 
-- `0`: **metadata**: the `content` is set to a stringified JSON object `{name: <username>, about: <string>, picture: <url, string>}` describing the user who created the event. A relay may delete older events once it gets a new one for the same pubkey.

[Extra metadata fields](24.md#kind-0) may be set. A relay may delete older events once it gets a new one for the same pubkey.
 - `1`: **text note**: the `content` is set to the **plaintext** content of a note (anything the user wants to say). Content that must be parsed, such as Markdown and HTML, should not be used. Clients should also not parse content as those.
 
 And also a convention for kind ranges that allow for easier experimentation and flexibility of relay implementation:

+NIP-35
+======
+
+Torrents
+-----------
+
+`draft` `optional`
+
+This NIP defined a new `kind 2003` which is a Torrent. 
+
+`kind 2003` is a simple torrent index where there is enough information to search for content and construct the magnet link. No torrent files exist on nostr.
+
+## Tags
+- `x`: V1 BitTorrent Info Hash, as seen in the [magnet link](https://www.bittorrent.org/beps/bep_0053.html) `magnet:?xt=urn:btih:HASH`
+- `file`: A file entry inside the torrent, including the full path ie. `info/example.txt`
+- `tracker`: (Optional) A tracker to use for this torrent
+
+In order to make torrents searchable by general category, you SHOULD include a few tags like `movie`, `tv`, `HD`, `UHD` etc.
+
+## Tag prefixes
+
+Tag prefixes are used to label the content with references, ie. `["i", "imdb:1234"]`
+
+- `tcat`: A comma separated text category path, ie. `["i", "tcat:video,movie,4k"]`, this should also match the `newznab` category in a best effort approach.
+- `newznab`: The category ID from [newznab](https://github.com/Prowlarr/Prowlarr/blob/develop/src/NzbDrone.Core/Indexers/NewznabStandardCategory.cs)
+- `tmdb`: [The movie database](https://www.themoviedb.org/) id.
+- `ttvdb`: [TV database](https://thetvdb.com/) id.
+- `imdb`: [IMDB](https://www.imdb.com/) id.
+- `mal`: [MyAnimeList](https://myanimelist.net/) id.
+- `anilist`: [AniList](https://anilist.co/) id.
+
+A second level prefix should be included where the database supports multiple media types.
+- `tmdb:movie:693134` maps to `themoviedb.org/movie/693134`
+- `ttvdb:movie:290272` maps to `thetvdb.com/movies/dune-part-two`
+- `mal:anime:9253` maps to `myanimelist.net/anime/9253`
+- `mal:manga:17517` maps to `myanimelist.net/manga/17517`
+
+In some cases the url mapping isnt direct, mapping the url in general is out of scope for this NIP, the section above is only a guide so that implementers have enough information to succsesfully map the url if they wish.
+
+```jsonc
+{
+  "kind": 2003,
+  "content": "<long-description-pre-formatted>",
+  "tags": [
+    ["title", "<torrent-title>"],
+    ["x", "<bittorrent-info-hash>"],
+    ["file", "<file-name>", "<file-size-in-bytes>"],
+    ["file", "<file-name>", "<file-size-in-bytes>"],
+    ["tracker", "udp://mytacker.com:1337"],
+    ["tracker", "http://1337-tracker.net/announce"],
+    ["i", "tcat:video,movie,4k"],
+    ["i", "newznab:2045"],
+    ["i", "imdb:tt15239678"],

+    ["i", "ttvdb:movie:290272"],
+    ["t", "movie"],
+    ["t", "4k"],
+  ]
+}
+```
+
+## Torrent Comments
+
+A torrent comment is a `kind 2004` event which is used to reply to a torrent event.
+
+This event works exactly like a `kind 1` and should follow `NIP-10` for tagging.

+# NIP-55
+
+## Android Signer Application
+
+`draft` `optional`
+
+This NIP describes a method for 2-way communication between an Android signer and any Nostr client on Android. The Android signer is an Android Application and the client can be a web client or an Android application.
+
+# Usage for Android applications
+
+The Android signer uses Intents and Content Resolvers to communicate between applications.
+
+To be able to use the Android signer in your application you should add this to your AndroidManifest.xml:
+
+```xml
+<queries>
+  <intent>
+    <action android:name="android.intent.action.VIEW" />
+    <category android:name="android.intent.category.BROWSABLE" />
+    <data android:scheme="nostrsigner" />
+  </intent>
+</queries>
+```
+
+Then you can use this function to check if there's a signer application installed:
+
+```kotlin
+fun isExternalSignerInstalled(context: Context): Boolean {
+  val intent =
+    Intent().apply {
+      action = Intent.ACTION_VIEW
+      data = Uri.parse("nostrsigner:")
+    }
+  val infos = context.packageManager.queryIntentActivities(intent, 0)
+  return infos.size > 0
+}
+```
+
+## Using Intents
+
+To get the result back from the Signer Application you should use `registerForActivityResult` or `rememberLauncherForActivityResult` in Kotlin. If you are using another framework check the documentation of your framework or a third party library to get the result.
+
+```kotlin
+val launcher = rememberLauncherForActivityResult(
+    contract = ActivityResultContracts.StartActivityForResult(),
+    onResult = { result ->
+        if (result.resultCode != Activity.RESULT_OK) {
+            Toast.makeText(
+                context,
+                "Sign request rejected",
+                Toast.LENGTH_SHORT
+            ).show()
+        } else {
+            val signature = activityResult.data?.getStringExtra("signature")
+            // Do something with signature ...
+        }
+    }
+)
+```
+
+Create the Intent using the **nostrsigner** scheme:
+
+```kotlin
+val intent = Intent(Intent.ACTION_VIEW, Uri.parse("nostrsigner:$content"))
+```
+
+Set the Signer package name:
+
+```kotlin
+intent.`package` = "com.example.signer"
+```
+
+Send the Intent:
+
+```kotlin
+launcher.launch(intent)
+```
+

+      ```
+
+## Using Content Resolver
+
+To get the result back from Signer Application you should use contentResolver.query in Kotlin. If you are using another framework check the documentation of your framework or a third party library to get the result.
+
+If the user did not check the "remember my choice" option, the npub is not in Signer Application or the signer type is not recognized the `contentResolver` will return null
+
+For the SIGN_EVENT type Signer Application returns two columns "signature" and "event". The column event is the signed event json
+
+For the other types Signer Application returns the column "signature"
+
+If the user chose to always reject the event, signer application will return the column "rejected" and you should not open signer application

+
+# Usage for Web Applications
+
+Since web applications can't receive a result from the intent, you should add a modal to paste the signature or the event json or create a callback url.
+
+If you send the callback url parameter, Signer Application will send the result to the url.
+
+If you don't send a callback url, Signer Application will copy the result to the clipboard.
+
+You can configure the `returnType` to be **signature** or **event**.
+
+Android intents and browser urls have limitations, so if you are using the `returnType` of **event** consider using the parameter **compressionType=gzip** that will return "Signer1" + Base64 gzip encoded event json

+Please update these lists when proposing new NIPs.
 
 ## Criteria for acceptance of NIPs
 
-1. They should be implemented in at least two clients and one relay -- when applicable.
+1. They should be fully implemented in at least two clients and one relay -- when applicable.
 2. They should make sense.
 3. They should be optional and backwards-compatible: care must be taken such that clients and relays that choose to not implement them do not stop working when interacting with the ones that choose to.
 4. There should be no more than one way of doing the same thing.
