+# wolfSSL Server Project
+
+This is an example wolfSSH Server based on the minimally viable wolfSSL [template](../wolfssh_template/README.md)
+
+See the [command line example client](https://github.com/wolfSSL/wolfssh/tree/master/examples/client)
+and the instructions in [wolfssh README.md](https://github.com/wolfSSL/wolfssh#readme)
+
+To connect:
+
+```bash
+TODO
+
+ssh -p 22222 jack@192.168.1.32
+```
+
+### Prerequisites
+
+It is assumed the [ESP-IDF environment](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/) has been installed.
+
+### Files Included
+
+- [main.c](./main/main.c) with a simple call to an Espressif library (`ESP_LOGI`) and a call to a wolfSSL library (`esp_ShowExtendedSystemInfo`) . 
+
+- See [components/wolfssl/include](./components/wolfssl/include/user_settings.h) directory to edit the wolfSSL `user_settings.h`.
+
+- Edit [main/CMakeLists.txt](./main/CMakeLists.txt) to add/remove source files.
+
+- The [components/wolfssl/CMakeLists.txt](./components/wolfssl/CMakeLists.txt) typically does not need to be changed.
+
+- Optional [VisualGDB Project](./VisualGDB/wolfssl_template_IDF_v5.1_ESP32.vgdbproj) for Visual Studio using ESP32 and ESP-IDF v5.1.
+
+- Edit the project [CMakeLists.txt](./CMakeLists.txt) to optionally point this project's wolfSSL component source code at a different directory:
+
+```
+set(WOLFSSL_ROOT "~/workspace/wolfssl-other-source")
+```
+
+
+## Getting Started:
+
+Here's an example using the command-line [idf.py](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/tools/idf-py.html).
+
+Edit your `WRK_IDF_PATH`to point to your ESP-IDF install directory.
+
+```
+WRK_IDF_PATH=/mnt/c/SysGCC/esp32/esp-idf/v5.1
+
+echo "Run export.sh from ${WRK_IDF_PATH}"
+. ${WRK_IDF_PATH}/export.sh
+
+# build the example:
+idf.py build
+
+# flash the code onto the serial device at /dev/ttyS19
+idf.py flash -p /dev/ttyS19 -b 115200
+
+# build, flash, and view UART output with one command:
+idf.py flash -p /dev/ttyS19 -b 115200 monitor
+```
+
+Press `Ctrl+]` to exit `idf.py monitor`. See [additional monitor keyboard commands](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/tools/idf-monitor.html).
+

+- [TLS Server](../wolfssl_server/README.md)
+- [Benchmark](../wolfssl_benchmark/README.md)
+- [Test](../wolfssl_test/README.md)
