+# Watchtower LDK client
+
+This is a watchtower client crate to interact with an [Eye of Satoshi tower](https://github.com/talaia-labs/rust-teos), and eventually with any [BOLT13](https://github.com/sr-gi/bolt13/blob/master/13-watchtowers.md) compliant watchtower. It is designed to be integrated into [LDK-Node](https://github.com/lightningdevkit/ldk-node).
+
+The crate manages all the client-side logic to send appointment to a number of registered towers every time a new commitment transaction is generated. It also keeps a summary of the messages sent to the towers and their responses.
+
+The client instance has the following methods:
+
+- `register_tower <tower_id>`: registers the user id (compressed public key) with a given tower.
+- `get_tower_info <tower_id>`: gets all the locally stored data about a given tower.
+- `retry_tower <tower_id>`: tries to send pending appointment to a (previously) unreachable tower.
+- `abandon_tower <tower_id>`: deletes all data associated with a given tower.
+- `ping_tower <tower_id>`: Polls the tower to check if it is online.
+- `list_towers`: lists all registered towers.
+- `get_appointment <tower_id> <locator>`: queries a given tower about an appointment.
+- `get_subscription_info <tower_id>`: gets the subscription information by querying the tower.
+- `get_appointment_receipt <tower_id> <locator>`: pulls a given appointment receipt from the local database.
+- `get_registration_receipt <tower_id>`: pulls the latest registration receipt from the local database.
+- `on_commitment_revocation <tx>`: sends appointments to the registered towers for every new commitment transaction.
+
+# Configuration
+
+## User identification and encryptions
+
+The constructor accepts a key pair that will be used as the user identifier. All requests from the user are signed using the secret key, so the tower can authenticate the user after the registration process (`register_tower`).
+
+All the appointments generated by the tower, as well as all the registered towers' data, are encrytped using aforementioned key are stored in a [KVStore](https://docs.rs/lightning/latest/lightning/util/persist/trait.KVStore.html) persisted storage like [VSS](https://github.com/lightningdevkit/vss-server) or [lightning_persister](https://docs.rs/lightning-persister/latest/lightning_persister/index.html)
+
+## Network configuration
+
+Network configuration options currently available options are:
+
+- `max_retry_count`: how many times a retry strategy will try to reach a temporary unreachable tower before giving up.
+- `retry_delay`: how long (in seconds) the client will wait before auto-retrying a failed tower.
+
+# Getting started as a developer
+
+## Creating a client instance
+```
+let teos_client = TeosClient::new(key_pair, storage)
+    .set_max_retry_count(10)
+    .set_retry_delay(1)
+    .build();
+```
+
+
+## Registering with a tower 
+
+Once the crate is instantiated, the first step is to register your node with an active tower. You can do so by calling:
+
+```
+async teos_client.register_tower(tower_connector: TowerConnector)) -> Result<RegistrationReceipt, Error>;
+```
+
+Where `tower_connector` represents the target tower public key. As a convenience, `tower_connector` may be of the form `tower_public_key@host` or `tower_public_key@host:port`. Port defaults to `9814`.
+
+### Example
+
+```
+teos_client = register_tower(TowerConnector::new("02bd2b759dd8a4fcef0f7d9692c105da8400d5da7942ee039e869fbfb8738ffde4@127.0.0.1:9814")).await?
+```
+
+If the tower is online, you should get back a response similar to this:
+
+```
+{
+   "user_id": "032fd79e4052531955cf3782b09b495a75919317573ba2fb4dca199652595ced2a",
+   "available_slots": 10000,
+   "subscription_expiry": 4712
+}
+```
+
+Where `available_slots` is the amount of free slots the user has available in the tower, `user_id` is the user's public key and `subscription_expiry` is the block height when the subscription expires. Generally speaking, a slot fits an appointment, so in this example the user can send **10000** appointments in roughly **one month**. 
+
+Notice that, ideally, the client and the tower have to agree on the **subscription details** (`available_slots` and `subscription_expiry`). Currently, those depend only on the tower, since it is offering the service for free. However, in the current state, hitting `register_tower` again will add another `10000` slots and reset the time to `current_height + roughtly_one_mont_in_blocks`.
+
+Note that this data will be stored internally inside of client's state and it does not require developer to do anything with it.
+
+## Sending data to the tower
+Once node is registered with at least one tower it can start sending appointments to the tower for every commitment transaction update on any of your channels using `on_commitment_revocation(tx: CommitmentRevocation) -> Result<(), Error>`. Where `CommitmentRevocation` has the following structure:
+```
+{
+    channel_id: String,
+    commit_num: u32,
+    commitment_txid: Txid,
+    penalty_tx: Transaction,
+}
+```
+In the current version, everything is sent to every registered tower (**full replication**). For the end user there is nothing to be done here, under normal conditions, the crate takes care of it.
+
+## Checking the state of the towers
+
+To find out more information about registered towers, you can use `list_towers` and `get_tower_info`:
+
+```
+list_towers() -> Vec<TowerInfo>
+```
+```
+{
+   "public_key": "02bd2b759dd8a4fcef0f7d9692c105da8400d5da7942ee039e869fbfb8738ffde4",
+    "net_addr": "http://localhost:9814",
+    "available_slots": 9996,
+    "subscription_expiry": 4712,
+    "status": "reachable",
+    "pending_appointments": [],
+    "invalid_appointments": []
+}
+```
+
+The overview contains the `id` and network address of the tower (`netaddr`), as well as the current `status` and two list of appointments: **pending** and **invalid**.
+
+The tower has 5 different statuses:
+
+- `reachable`: the tower is reachable at the given network address.
+- `temporarily unreachable`: the tower is temporarily unreachable, meaning that one of the last requests sent to it has failed.
+- `unreachable`: the tower has been unreachable for a while.
+- `misbehaving`: the tower has sent us incorrect data.
+- `subscription error`: the subscription with the tower has expired or run out of slots.
+
+The main difference between `temporarily unreachable` and `unreachable` is the amount of time that has passed since we last received a response. If a tower is temporarily unreachable, a backoff strategy is triggered and all the appointments that cannot be delivered are stored under `pending_appointments`. If the tower comes back online within the retry strategy, every pending appointment is sent through and the tower is flagged back as `reachable`. However, if the backoff strategy ends up giving up, the tower is flagged as `unreachable`.
+
+If the client receives data from a tower that is not properly signed, the tower is flagged as `misbehaving` and it is abandoned, meaning that no more appointments are sent to it. This state should never be reached by honest towers.
+
+A `subscription error` means that the subscription needs to be renewed (hit `registertower` again).
+
+Regarding `pending_appointments` and `invalid_appointments` they store the data that is pending to be sent to the tower (for unreachable towers) and the appointments that have been rejected by the tower for being invalid, respectively. The latter should never get populated for honest clients.
+
+`gettowerinfo` provides more detailed information about the tower:
+
+**Usage**
+
+```
+get_tower_info tower_id
+```
+
+**Call**
+
+```
+get_tower_info 02bd2b759dd8a4fcef0f7d9692c105da8400d5da7942ee039e869fbfb8738ffde4
+```
+
+**Return**

+         "to_self_delay": 42
+      }
+   },
+   "invalid_appointments": {}
+}
+```
+
+Notice that there are is a new field in this report: `appointments`.
+
+`appointments` contains a collection of `locator:tower_signature` pairs of all the appointments sent and accepted by the tower.
+
+The report may also contain a `misbehaving_proof` field if the tower has misbehaved (this is not the case for this example). The proof would look as follows:
+
+```
+   "misbehaving_proof": {
+      "locator": "3ebd6c5a4d5ec18c815ad9fcda9aac75",
+      "appointment_receipt": {
+         "user_signature": "d7efykp63dy69jrtc3r65pssbdhp4335etq3jap1zqk135qmrtyhr8ghbdhw8y8f7nsjgmm9eoyhsfj6yugzq1bu657frmwwrudr9gpt",
+         "start_block": 391,
+         "signature": "rd41nsmhtjsawhc9pta1p5na7kmsyk48xttjy4bt3tbkbajboyzfq6mpamkjixs1w7qotocwjg3sxnbzg6uduec4cnahhkmctgddjn8w"
+      },
+      "recovered_id": "02bd2b759dd8a4fcef0f7d9692c105da8400d5da7942ee039e869fbfb8738ffde4"
+   }
+```
+
+Finally, notice how `pending_appointments` now contains all the data about the pending appointments (**the full appointment**). The same applies to `invalid_appointments`.
+
+## Manually retrying a tower (YAGNI ?)
+If a tower has been flagged as **unreachable** (after the default backoff has failed) or there has been a **subscription error**, the tower won't be tried again until the user manually requests so. This can be managed with the `retry_tower` command:
+
+**Usage**
+
+```
+retry_tower tower_id
+```
+**Call**
+
+```
+retry_tower 02bd2b759dd8a4fcef0f7d9692c105da8400d5da7942ee039e869fbfb8738ffde4
+```
+**Return**
+
+```
+"Retrying 02bd2b759dd8a4fcef0f7d9692c105da8400d5da7942ee039e869fbfb8738ffde4"
+```
+
+Notice that this only works if the tower is **unreachable**. A tower cannot be retried if it is already being retried (**temporarily unreachable**).
+
+## Query data from a tower
+Data can be queried from a tower to check, for instance, that the tower is keeping it or that it is correct. This can be done using the `get_appointment` command:
+
+**Usage**
+
+```
+get_appointment <tower_id> <locator>
+```
+**Call**
+
+```
+get_appointment 02bd2b759dd8a4fcef0f7d9692c105da8400d5da7942ee039e869fbfb8738ffde4 b851b8ec05f5809b9a710f7d9d24db6c
+```
+
+**Return**
+
+```
+{
+   "appointment": {
+      "locator": "b851b8ec05f5809b9a710f7d9d24db6c",
+      "encrypted_blob": "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",
