+## Introduction
+
+In this README, we'll provide initial instructions for booting a Stability node.
+
+## Generating Keys
+
+A Stability node uses 3 keys to operate:
+
+1. ECDSA key for ImOnline Pallet
+2. ECDSA key for Aura (Stability's consensus mechanism)
+3. ED25519 key for Grandpa (Stability's finality mechanism)
+
+At Stability, we recommend generating a single SEED for all these keys and using it to produce all the necessary keys from it.
+
+To generate a SEED, you can either use a reliable SEED generation service (ensure its safety) or use the Stability node itself, which incorporates a SEED generation mechanism. To achieve this, execute the following command:
+
+```sh
+./target/release/stability key generate
+```
+
+This command will produce the SEED.
+
+## Insert Keys in the Node
+
+To insert the keys using the seed previously generated, use the following script
+
+```sh
+   ## TO RUN THIS COMMAND YOU SHOULD DEFINE
+   ## $SEED - Seed phrase from which Stability keys are derived
+   ## $PATH - Path where you save your node data
+  ./target/release/stability key insert  \
+  --keystore-path  $PATH/chains/alphanet/keystore \
+  --base-path $PATH \
+  --scheme ecdsa \
+  --suri "$SEED" \
+  --key-type aura
+
+  ./target/release/stability key insert \
+  --keystore-path  $PATH/chains/alphanet/keystore \
+  --base-path $PATH \
+  --scheme Ed25519 \
+  --suri "$SEED" \
+  --key-type gran
+
+  ./target/release/stability key insert \
+  --keystore-path  $PATH/chains/alphanet/keystore \
+  --base-path $PATH \
+  --scheme ecdsa \
+  --suri "$SEED" \
+  --key-type imon
+```
+
+With this, you will have inserted the keys into the node, ready to run a Stability validator.
+
+## Running a Stability Validator Node
+
+To run a Stability node, execute the following command:
+
+```sh
+./target/release/stability --chain alphanet
+```
+
+Additionally, you can configure the following flags:
+
+- `--validator`: Assumes that you are a validator and begins validation if you are on the validators' list.
+- `--pruning archive`: Runs your node in archival mode. An archival node maintains a complete copy and allows queries on any historical chain state.
+- `--unsafe-rpc-external --rpc-cors all --unsafe-ws-external`: Use if your node will be accessed from a system external to your localhost.
+- `--bootnodes`: A list of p2p nodes for Stability to join the network. What is known as bootnodes
+- `--base-path`: Specifies a custom base path for the data folder

+# Monitoring
+
+Substrate provides detailed metrics about your network's operations, these metrics can help to have insights about the number of peers connects, block finalized, peaks of transactions, among others.
+
+The client presents telemetry in a format compatible with a Prometheus endpoint. This allows for its visualization through charts or integration with Grafana dashboards.
+
+This guide focuses solely on configuring a local environment to monitor our development chain. For additional details, please refer to the provided link.
+
+- https://docs.substrate.io/tutorials/build-a-blockchain/monitor-node-metrics/
+
+## Quick start
+
+To monitor your local client, we offer a `docker-compose` file that facilitates the setup of both `grafana` and `prometheus` services:
+
+- Prometheus is an open-source tool tailored for monitoring and alerting in cloud-native ecosystems. It gathers and retains metrics, and features an API that can be tapped by other applications, such as dashboards.
+- Grafana aids in visualizing the collected monitoring data. It offers tools to craft charts and tables, enhancing business intelligence operations.
+
+For this last one, we also offer a pre-set dashboard that displays various metrics sourced from Substrate.
+
+To begin with, we'll execute the `docker-compose` that houses the two previously mentioned services.
+
+```bash
+$ docker-compose -f docker/monitoring/docker-compose.yml
+```
+
+After it's up and running, proceed to launch the client with the `--prometheus-external` flag activated. The client metrics can be viewed at: http://localhost:9165/metrics
+
+At this point, we're all set to begin monitoring the node. To do this, access Grafana locally via: http://localhost:3000.
+The username and password are both set to `admin`.
+
+You can locate the pre-configured dashboard by navigating to the left menu and selecting **Dashboards > General**.

+- [3. Other considerations](#3-other-considerations)
+
+## 1. Introduction
+
+Zero Gas Transactions represent an innovative type of transaction developed in Stability. Their main appeal lies in their ability to execute without incurring gas fees. Moreover, these transactions are stored in a private mempool, separate from the network's validating nodes.
+
+This system contrasts with [Sponsored Transactions](SPONSORED-TRANSACTIONS.md), where, even if the user doesn't pay, a third entity named "sponsor" assumes the execution costs. In the case of Zero Gas Transactions, the gas fee is nil for all parties involved. This is because the validator itself, when mining the transaction, decides to include it during its validation cycle, resulting in a gas fee of 0.
+
+## 2. How do Zero Gas Transactions work?
+
+The mechanism underlying Zero Gas Transactions is relatively straightforward. As mentioned earlier, the validator is responsible for selecting and processing these no-cost transactions during their validation cycle.
+
+### External Private Mempool
+
+The validator selects the transactions from an external private mempool. This mempool is a service that exposes a GET HTTP interface and returns a list of transactions with the following format:
+
+```json
+{
+    "transactions": [
+        "..." // signed Ethereum transaction in hexadecimal format without the 0x prefix
+    ]
+}
+```
+
+All transactions retrieved from this mempool will be processed as Zero Gas Transactions.
+
+### Setting up the External Mempool for Validators
+
+If you are a validator and wish to integrate this functionality, you simply need to configure your node with the `--zero-gas-tx-pool <URL>` parameter. This option determines the HTTP address to which the validating node will make GET requests to obtain the Zero Gas Transactions during its validation cycle.
+
+## 3. Other considerations
+
+- If the external mempool takes longer than 100ms to respond, the Zero Gas Transactions will be ignored.
+- If the JSON format returned by the external private mempool is incorrect, the transactions will be ignored.
+- It is essential that, to be processed as a Zero Gas Transaction, the `gasPriceLimit` parameter is set to 0.
