-### What is this?
-System that allows you to build your own infrastructure based on identical nodes and various scripts written using built-in Lua 5.1, shebang scripts (scripts that start with the `#!` symbols), compiled binaries.

-### Features
-Go Sally is not viable at the moment, but it already has the ability to run embedded scripts, log slog events to stdout, handle RPC like requests, and independent automatic update from the repository (my pride, to be honest).
 
-### Example of use
-The basic directory tree looks something like this
-```
-.
-├── bin
-│   └── node			Node core binary file
-├── com
-│   ├── echo.lua
-│   ├── _globals.lua	Declaring global variables and functions for all internal scripts (also required for luarc to work correctly)
-│   └── _prepare.lua	Script that is executed before each script launch
-└── config.yaml
+> ⚡ **What, Why, Why Care?**
 
-3 directories, 5 files
+> **What:** Go Sally is a lightweight decentralized node system with Lua scripting and JSON-RPC2.0.
 
-```
-Launch by command 
+> **Why:** Large admin tools are too heavy, and Raspberry Pi and small servers require a lightweight, modular architecture.
+
+> **Why Care:** Create, automate, and expand your infrastructure quickly, without unnecessary software or dependencies.

+> If you see "💡" in the text, it means the information below is about plans for the future of the project.
+
+## Core features
+- **Decentralized nodes**<details>this means that *multiple GS[^1] nodes can be located on a single machine*, provided no attempt is made to disrupt, sabotage, or bypass the built-in protection mechanism against running a node under the same identifier as one already running in the system. Identification plays a role in node communication. 💡 In the future, we plan to create tools for conveniently building distributed systems using node identification.
+**Why Care?** Multiple nodes on one machine allow testing, experimentation, and scaling small infrastructures without extra hardware or complex setup.</details>
+- **RPC request processing**<details>the GS operates *using HTTP/https and the JSONRPC2.0 protocol.* Unlike gRPC, jsonrpc is extremely simple, allows for easy sending of requests from the browser, and does not require any additional code compilation. **Why Care?** Easy-to-use API means you can control nodes from anywhere, including lightweight web clients, without compiling extra code.</details>
+- **Lua script-based methods**<details>*The gopher-lua library is used, providing full support for Lua 5.1.* scripts implement libraries for interacting with sessions (receiving parameters and sending responses), hashing, logging, and more. This allows you to quickly write business logic on the fly without touching the lower layers of abstraction, which also eliminates unnecessary compilation and the risk of breaking the codebase.
+  Example of the "echo" method:
+  ```lua
+  local session = require("internal.session")
+  -- import the internal library for interacting with sessions
+
+  session.response.send(session.request.params.get())
+  -- send everything passed in the parameters in response.
+  ```
+  **Why Care?** You can extend node behavior dynamically, write custom logic fast, and iterate without recompiling — perfect for experiments or automation.
+  </details>
+- **Relatively flexible configuration** <details>
+you can configure the server port, address, name, node settings, and more. 💡 More settings are planned in the future. **Why Care?** Configure nodes for any environment, from Raspberry Pi to VPS, without touching the source code. obviously :)</details>
+- ***And more in the future***
+
+> [!IMPORTANT]
+> This is the beginning of the project's development, and some aspects of it may be unstable, unfinished, and the text about it may be overly ambitious. It's just a matter of time.
+
+## Quick start
 ```bash
+git clone https://github.com/akyaiy/GoSally-mvp.git && \
+cd GoSally-mvp && \
+make build && \
+echo -e "node:\n  com_dir: \"%path%/com\"" > config.yaml && \
+mkdir -p com && \
+echo -e 'local session = require("internal.session")\n\nsession.response.send(session.request.params.get())' > com/echo.lua && \
 ./bin/node run
 ```
-or for structured logs
-```bash
-./bin/node run | jq
-```
 
-Example of GET request to server
+If you have problems, make sure you have all [dependencies](https://github.com/akyaiy/GoSally-mvp/wiki/Getting-started#installing-dependencies) installed, otherwise [file an issue report](https://github.com/akyaiy/GoSally-mvp/issues)
+
+### Test it
 ```bash
-curl -s http://localhost:8080/api/v1/com/echo?msg=Hello
+curl -X POST http://localhost:8080/com \
+  -d '{"jsonrpc":"2.0","context-version": "v1","method":"echo","params":["Hi!!"],"id":1}'
 ```
-Then the response from the server
+Expected response:
 ```json
 {
-  "ResponsibleAgentUUID": "4593a87000bbe088f4e79c477e9c90d3",
-  "RequestedCommand": "echo",
-  "Response": {
-    "answer": "Hello",
-    "status": "ok"
+  "jsonrpc": "2.0",
+  "id": 1,
+  "result": [
+    "Hi!!"
+  ],
+  "data": {
+    "responsible-node": "a0e1c440473ffd4d87e32cff2717f5b3",
+    "salt": "f26df732-a3be-4400-8e71-b8dc3ba705fc",
+    "checksum-md5": "cd8bec6a365d1b8ee90773567cb3ad0a"
   }
 }
-
 ```
 
-### How to install
-**You don't need it now, but you can figure it out with the Makefile**
+## Concept
+The project was originally conceived as a tool for building infrastructure using relatively *small nodes with limited functionality*. 💡 In the future, we plan to create a *web interface for interacting with nodes, administration, and configuration*. The concept is simple: suppose we have a node that manages Bind9. It has all the necessary methods for interacting with the service: creating new zones, viewing zone status, changing configuration, and server operation status. All of this works only through manual configuration, with the exception of larger solutions like Webmin and the BIND DNS Server module. The big problem is that while we only needed web configuration for Bind9, we have to pull in a massive amount of software just to implement one module. What if the service is hosted on a low-power Raspberry Pi? That's where GS nodes come in. By default, GS nodes communicate only through API calls, so 💡 in the future, we plan to create a dedicated, also programmable, web node that will provide convenient access to node management.
+
+There's an obvious advantage here: transparency. The project is *completely open source and aims to support community-driven node functionality*. 💡 In the future, we plan to create a "store" similar to Docker Hub, which will contain scripts for configuring bind9, openvpn, and even custom projects.
+
+## API
+As mentioned earlier, *the server handles [jsonrpc2.0](https://www.jsonrpc.org/specification) requests*
+```json
+{
+    "jsonrpc": "2.0",
+    "context-version": "v1",
+    "method": "test",
+    "params": [
+        "Hi!!"
+    ],
+    "id": 1
+}
+```
+This is a typical example of a request using the jsonrpc2.0 protocol.
+```json
+{
+    "jsonrpc": "2.0",
+    "id": 1,
+    "result": [
+        "Hi!!"
+    ],
+    "data": {
+        "responsible-node": "2ad6ebeaf579a7c52801fb6c9dd1b83d",
+        "salt": "e7a81115-01c1-45b1-9618-0eae0ff26451",
+        "checksum-md5": "cd8bec6a365d1b8ee90773567cb3ad0a"
+    }
+}
+```
+In the result field, we see the echo method's response. Those familiar with the jsonrpc2.0 specification will notice that the data structure here is unclear. This is my extension, which has three functions:
+| Field | Type | Description |
+|--------|------|-------------|
+| `responsible-node` | string | ID of the node that executed the task |
+| `salt` | string | Random value for each request — can be used to check that the response is unique |
+| `checksum-md5` | string | MD5 hash of the result field — can be used to avoid processing identical results separately |
