+## Tested on
+
+1. [ESP32 ESP-IDF v5.5.3](https://docs.espressif.com/projects/esp-idf/en/v5.5.3/esp32/index.html)
+
+## SAST Tools
+
+[PVS-Studio](https://pvs-studio.com/pvs-studio/?utm_source=website&utm_medium=github&utm_campaign=open_source) - static analyzer for C, C++, C#, and Java code.
+
+## Note
+
+Messages are built using the format defined in [RFC 5424](https://datatracker.ietf.org/doc/html/rfc5424).
+
+## Using
+
+In an existing project, run the following command to install the component:
+
+```text
+cd ../your_project/components
+git clone https://github.com/aZholtikov/zh_syslog.git
+```
+
+In the application, add the component:
+
+```c
+#include "zh_syslog.h"
+```
+
+## Example
+
+Sending messages:
+
+```c
+#include "nvs_flash.h"
+#include "esp_netif.h"
+#include "esp_wifi.h"
+#include "esp_timer.h"
