+
+---
+
+Welcome to Espressif's Advanced ESP-IDF Workshop!
+
+## Introduction
+
+In this hands-on workshop, you'll develop a solid understanding of the ESP-IDF framework, included modular development via components, event loops, core dumps, and security features.

+
+## Agenda
+
+The workshop is structured into four parts. Here's the outline:
+
+* Part 1: **Components**
+
+  * Lecture 1 -- What is a component, how to create it, and how to support multiple hardware versions via BSPs and multi-config
+  * Assignment 1.1 -- Refactor the code creating the alarm component
+  * Assignment 1.2 -- Refactor the code creating the `cloud_manager` component
+  * Assignment 1.3 -- Multiple configuration using `sdkconfig`
+
+* Part 2: **Event Loops**
+
+  * Lecture 2 -- Event loop basics in ESP-IDF, using timer events, and separation of concerns
+  * Assignment 2.1 -- Refactor the code to use the event loop mechanism
+  * Assignment 2.2 -- Add a gpio event to the event loop
+
+* **Break** (15 minutes)
+
+* Part 3: **Performance and crash analysis**
+
+  * Lecture 3 -- Application size analysis and core dumps
+  * Assignment 3.1 -- Analyze application size and suggest optimizations
+  * Assignment 3.2 -- Analyze a crash using core dumps (guided)
+  * Assignment 3.3 -- Analyze a crash using core dumps (optional)
+
+* Part 4: **OTA and Security Features**
+
+  * Lecture 4 -- OTA fundamentals, partition table configuration, secure bootloader, flash encryption
+  * Assignment 4.1 -- Modify the partition table to support OTA
+  * Assignment 4.2 -- Use a custom partition table
+  * Assignment 4.3 -- Enable flash encryption
+  <!-- * Assignment 4.4 -- Secure bootloader (optional - TBD) -->
+
+## Prerequisites
+
+To follow this workshop, make sure you meet the prerequisites listed below.
+
+* Good knowledge of:
+
+  * C programming and its linker
+  * Call back functions and function pointers
+  * MQTT protocol and usage
+
+* Embedded programming
+
+  * Flashing / Programming, linking
+  * Familiarity with MCU peripherals such as GPIO and I2C
+  * Basic experience with ESP-IDF
+* Tools installation (VSCode + ESP-IDF extension)
+
+> We strongly recommend installing VSCode and the ESP-IDF plugin before the workshop begins. If you run into any issues, there will be some time during the first assignment to complete the installation.

+## Workshop
+
+Without further delay, let’s get started! You’ll find links to each part of the workshop below.
+
+The first lecture builds on the code in [`assignment_1_1_base`](https://github.com/FBEZ-docs-and-templates/devrel-advanced-workshop-code/tree/main/assignment_1_1_base).
+
+If you’re unable to complete a particular assignment, please download its prerequisite as shown in the diagram below.
+
+```goat
+assignment_1_1_base ---> assignment_1_1 ---> assignment_1_2 -+-> assignment_1_3
+                                                  |
+                                                  +-> assignment_2_1 ---> assignment_2_2 ---> assignment_3_1
+
+assignment_3_2_base --------------------------------> assignment 3_2 ---> assignment 4_1 ---> assignment 4_2
+```
+<br>
+
+
+{{< alert icon="circle-info" cardColor="#b3e0f2" iconColor="#04a5e5">}}
+Even if you complete all assignments successfully, you’ll still need to download at least `assignment_1_1_base` and `assignment_3_2_base`.
