-                By default, the application is built as a binary file in a format compatible with
-                the ESP32 bootloader. In addition to this application, 2nd stage bootloader is
-                also built. Application and bootloader binaries can be written into flash and
-                loaded/executed from there.
-
-                Another option, useful for only very small and limited applications, is to only link
-                the .elf file of the application, such that it can be loaded directly into RAM over
-                JTAG. Note that since IRAM and DRAM sizes are very limited, it is not possible to
-                build any complex application this way. However for kinds of testing and debugging,
-                this option may provide faster iterations, since the application does not need to be
-                written into flash.
-                Note that at the moment, ESP-IDF does not contain all the startup code required to
-                initialize the CPUs and ROM memory (data/bss). Therefore it is necessary to execute
-                a bit of ROM code prior to executing the application. A gdbinit file may look as follows:
-
-                    # Connect to a running instance of OpenOCD
-                    target remote :3333
-                    # Reset and halt the target
-                    mon reset halt
-                    # Run to a specific point in ROM code,
-                    #  where most of initialization is complete.
-                    thb *0x40007d54
-                    c
-                    # Load the application into RAM
-                    load
-                    # Run till app_main
-                    tb app_main
-                    c
-
-                Execute this gdbinit file as follows:
-
-                    xtensa-esp32-elf-gdb build/app-name.elf -x gdbinit
-
-                Recommended sdkconfig.defaults for building loadable ELF files is as follows.
-                CONFIG_APP_BUILD_TYPE_ELF_RAM is required, other options help reduce application
-                memory footprint.

+[![alt text](https://readthedocs.org/projects/docs/badge/?version=latest "Documentation Status")](https://esp-idf.readthedocs.io/en/latest/?badge=latest)
 
-ESP-IDF is the development framework for Espressif SoCs (released after 2016<sup>[1](#fn1)</sup>) provided for Windows, Linux and macOS.
+ESP-IDF is the official development framework for the [ESP32](https://espressif.com/en/products/hardware/esp32/overview) chip.
 
-# Developing With ESP-IDF
+# Developing With the ESP-IDF
 
 ## Setting Up ESP-IDF
 
-See https://idf.espressif.com/ for links to detailed instructions on how to set up the ESP-IDF depending on chip you use.
+See setup guides for detailed instructions to set up the ESP-IDF:
 
-**Note:** Each SoC series and each ESP-IDF release has its own documentation. Please see Section [Versions](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/versions.html) on how to find documentation and how to checkout specific release of ESP-IDF.
-
-### Non-GitHub forks
-
-ESP-IDF uses relative locations as its submodules URLs ([.gitmodules](.gitmodules)). So they link to GitHub.
-If ESP-IDF is forked to a Git repository which is not on GitHub, you will need to run the script
-[tools/set-submodules-to-github.sh](tools/set-submodules-to-github.sh) after git clone.
-The script sets absolute URLs for all submodules, allowing `git submodule update --init --recursive` to complete.
-If cloning ESP-IDF from GitHub, this step is not needed.

-## Setup Build Environment
-
-(See the Getting Started guide listed above for a full list of required steps with more details.)
-
-* Install host build dependencies mentioned in the Getting Started guide.
-* Run the install script to set up the build environment. The options include `install.bat` or `install.ps1` for Windows, and `install.sh` or `install.fish` for Unix shells.
-* Run the export script on Windows (`export.bat`) or source it on Unix (`source export.sh`) in every shell environment before using ESP-IDF.
-
 ## Configuring the Project
 
-* `idf.py set-target <chip_name>` sets the target of the project to `<chip_name>`. Run `idf.py set-target` without any arguments to see a list of supported targets.
-* `idf.py menuconfig` opens a text-based configuration menu where you can configure the project.
+`make menuconfig`
+
+* Opens a text-based configuration menu for the project.
+* Use up & down arrow keys to navigate the menu.
+* Use Enter key to go into a submenu, Escape key to go out or to exit.
+* Type `?` to see a help screen. Enter key exits the help screen.
+* Use Space key, or `Y` and `N` keys to enable (Yes) and disable (No) configuration items with checkboxes "`[*]`"
+* Pressing `?` while highlighting a configuration item displays help about that item.
+* Type `/` to search the configuration items.
+
+Once done configuring, press Escape multiple times to exit and say "Yes" to save the new configuration when prompted.
 
 ## Compiling the Project
 
-`idf.py build`
+`make all`
 
 ... will compile app, bootloader and generate a partition table based on the config.
 
 ## Flashing the Project
 
-When the build finishes, it will print a command line to use esptool.py to flash the chip. However you can also do this automatically by running:
+When `make all` finishes, it will print a command line to use esptool.py to flash the chip. However you can also do this from make by running:

+`make flash`
 
-Replace PORT with the name of your serial port (like `COM3` on Windows, `/dev/ttyUSB0` on Linux, or `/dev/cu.usbserial-X` on MacOS. If the `-p` option is left out, `idf.py flash` will try to flash the first available serial port.
+This will flash the entire project (app, bootloader and partition table) to a new chip. The settings for serial port flashing can be configured with `make menuconfig`.

+You don't need to run `make all` before running `make flash`, `make flash` will automatically rebuild anything which needs it.
 
 ## Viewing Serial Output
 
-The `idf.py monitor` target uses the [idf_monitor tool](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/idf-monitor.html) to display serial output from Espressif SoCs. idf_monitor also has a range of features to decode crash output and interact with the device. [Check the documentation page for details](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/idf-monitor.html).

[Check the documentation page for details](https://esp-idf.readthedocs.io/en/latest/get-started/idf-monitor.html).
 
 Exit the monitor by typing Ctrl-].
 
-To build, flash and monitor output in one pass, you can run:
+To flash and monitor output in one pass, you can run:
 
-`idf.py flash monitor`
+`make flash monitor`
 
-## Compiling & Flashing Only the App
+## Compiling & Flashing Just the App
 
 After the initial flash, you may just want to build and flash just your app, not the bootloader and partition table:
 
-* `idf.py app` - build just the app.
-* `idf.py app-flash` - flash just the app.
+* `make app` - build just the app.
+* `make app-flash` - flash just the app.
 
-`idf.py app-flash` will automatically rebuild the app if any source files have changed.
+`make app-flash` will automatically rebuild the app if it needs it.
 
 (In normal development there's no downside to reflashing the bootloader and partition table each time, if they haven't changed.)
 
+## Parallel Builds
+
+ESP-IDF supports compiling multiple files in parallel, so all of the above commands can be run as `make -jN` where `N` is the number of parallel make processes to run (generally N should be equal to or one more than the number of CPU cores in your system.)
+
+Multiple make functions can be combined into one. For example: to build the app & bootloader using 5 jobs in parallel, then flash everything, and then display serial output from the ESP32 run:
+
+```
+make -j5 flash monitor
+```
+
+## The Partition Table
+
+Once you've compiled your project, the "build" directory will contain a binary file with a name like "my_app.bin". This is an ESP32 image binary that can be loaded by the bootloader.
+
+A single ESP32's flash can contain multiple apps, as well as many different kinds of data (calibration data, filesystems, parameter storage, etc). For this reason a partition table is flashed to offset 0x8000 in the flash.
+
+Each entry in the partition table has a name (label), type (app, data, or something else), subtype and the offset in flash where the partition is loaded.
+
+The simplest way to use the partition table is to `make menuconfig` and choose one of the simple predefined partition tables:
+
+* "Single factory app, no OTA"
+* "Factory app, two OTA definitions"
+
+In both cases the factory app is flashed at offset 0x10000. If you `make partition_table` then it will print a summary of the partition table.
+
+For more details about partition tables and how to create custom variations, view the [`docs/api-guides/partition-tables.rst`](docs/api-guides/partition-tables.rst) file.
+
 ## Erasing Flash
 
-The `idf.py flash` target does not erase the entire flash contents. However it is sometimes useful to set the device back to a totally erased state, particularly when making partition table changes or OTA app updates. To erase the entire flash, run `idf.py erase_flash`.

-# Espressif 物联网开发框架
-
-* [English Version](./README.md)
-
-ESP-IDF 是由乐鑫官方针对乐鑫各系列芯片产品（发布于 2016 年后<sup>[1](#fn1)</sup>）推出的开发框架，支持 Windows、Linux 和 macOS 操作系统。
-
-# 使用 ESP-IDF 进行开发
-
-## 搭建 ESP-IDF 开发环境
-
-关于不同芯片如何搭建 ESP-IDF 的开发环境，请参考 https://idf.espressif.com/。
-
-**注意：** 不同系列芯片和不同 ESP-IDF 版本都有其对应的文档。请参阅[版本](https://docs.espressif.com/projects/esp-idf/zh_CN/latest/esp32/versions.html)部分，获得关于如何查找文档以及如何检出 ESP-IDF 的特定发行版的详细信息。
-
-### 非 GitHub 分叉的 ESP-IDF 项目
-
-ESP-IDF 中的子模块采用相对路径（[详见 .gitmodules 文件](.gitmodules)），所以它们会指向 GitHub。
-如果 ESP-IDF 被分叉到的仓库不在 GitHub 上，那么你需要在克隆结束后运行该脚本 [tools/set-submodules-to-github.sh](tools/set-submodules-to-github.sh)。
-
-这个脚本会为所有的子模块设置绝对路径，接着可以通过 `git submodule update --init --recursive` 完成子模块的更新。
-如果 ESP-IDF 是从 GitHub 上克隆得到，则不需要此步骤。
-
-## 寻找项目
-
-除了入门指南中提到的 [esp-idf 模板项目](https://github.com/espressif/esp-idf-template)，ESP-IDF 的 [examples](examples) 目录下还带有很多其它示例项目。
-
-一旦找到了需要的项目，便可以进入该目录，执行配置和构建操作。
-
-如果要基于示例工程开始你自己的项目，请将示例工程复制到 ESP-IDF 目录之外。
-
-# 快速参考
-
-详细的使用方法请参考上面入门指南的链接，这里仅仅列举一些 ESP-IDF 项目开发中常用的命令：
-
-## 设置构建环境
-
-请参考入门指南中列出的详细步骤。
-
-* 在主机中安装入门指南中提到的构建所依赖的工具。
-* 运行安装脚本来设置构建环境。可为 Windows shell 选择 `install.bat` 或 `install.ps1`，为 Unix shell 选择 `install.sh` 和 `install.fish`。
-* 在使用 ESP-IDF 之前，需要在 shell 中运行导出脚本。Windows 下可运行 `export.bat`，Unix 下可运行 `source export.sh`。
-  
-## 配置项目
-
-* `idf.py set-target <chip_name>` 可将项目的目标芯片设置为 `<chip_name>`。运行 `idf.py set-target`，不用带任何参数，可查看所有支持的目标芯片列表。
-* `idf.py menuconfig` 可打开一个基于文本的配置菜单，可以用来对项目进行配置。
-
-## 编译项目
-
-`idf.py build`
-
-编译应用程序，引导程序，并根据配置生成分区表。
-
-## 烧写项目
-
-当构建结束，终端会打印出一条命令行，告知如何使用 esptool.py 工具烧写项目到芯片中。但你也可以运行下面这条命令来自动烧写：
-
-`idf.py -p PORT flash`
-
-将其中的 PORT 替换为系统中实际串口的名字（比如 Windows 下的 `COM3`，Linux 下的 `/dev/ttyUSB0`，或者 macOS 下的 `/dev/cu.usbserial-X`。如果省略 `-p` 选项，`idf.py flash` 会尝试使用第一个可用的串口进行烧写。
-
-这会烧写整个项目（包括应用程序，引导程序和分区表）到芯片中，此外还可以使用 `idf.py menuconfig` 来调整串口烧写相关的配置。
-
-不必先运行 `idf.py build` 再运行 `idf.py flash`，`idf.py flash` 会根据需要自动重新构建项目。
-
-## 观察串口输入
-
-`idf.py monitor` 会调用 [idf_monitor 工具](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/idf-monitor.html)来显示乐鑫芯片的串口输出。`idf_monitor` 还包含一系列的功能来解析程序崩溃后的输出结果并与设备进行交互。更多详细内容，请参阅[文档](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/idf-monitor.html).
-
-输入 `Ctrl-]` 可退出监视器。
-
-想要一次性执行构建、烧写和监视，可以运行如下命令：
-
-`idf.py flash monitor`
-
-## 仅编译并烧写应用程序
-
-在第一次烧写过后，你可能只想构建并烧写你的应用程序，不包括引导程序和分区表：
-
-* `idf.py app` - 仅构建应用程序。
-* `idf.py app-flash` - 仅烧写应用程序。
-
-`idf.py app-flash` 会自动判断是否有源文件发生了改变然后重新构建应用程序。
-
-（在正常的开发中，即使引导程序和分区表没有发生变化，每次都重新烧写它们并不会带来什么危害。）
-
-## 擦除 Flash
-
-`idf.py flash` 并不会擦除 flash 上所有的内容，但是有时候我们需要设备恢复到完全擦除的状态，尤其是分区表发生了变化或者 OTA 应用升级时。要擦除整块 flash 请运行 `idf.py erase_flash`。
-
-这条命令还可以和其余命令整合在一起，`idf.py -p PORT erase_flash flash` 会擦除一切然后重新烧写新的应用程序、引导程序和分区表。
-
-# 其它参考资源
-
-* 最新版的文档：https://docs.espressif.com/projects/esp-idf/，该文档是由本仓库 [docs 目录](docs) 构建得到。
-
-* 可以前往 [esp32.com 论坛](https://esp32.com/) 提问，挖掘社区资源。

-// Target is not allowed to perform other RTT operations while string still has not been stored completely.
-// Otherwise we would probably end up with a mixed string in the buffer.
-// If using  RTT from within interrupts, multiple tasks or multi processors, define the SEGGER_RTT_LOCK() and SEGGER_RTT_UNLOCK() function here.
-//
-// SEGGER_RTT_MAX_INTERRUPT_PRIORITY can be used in the sample lock routines on Cortex-M3/4.
-// Make sure to mask all interrupts which can send RTT data, i.e. generate SystemView events, or cause task switches.
-// When high-priority interrupts must not be masked while sending RTT data, SEGGER_RTT_MAX_INTERRUPT_PRIORITY needs to be adjusted accordingly.
-// (Higher priority = lower priority number)
-// Default value for embOS: 128u
-// Default configuration in FreeRTOS: configMAX_SYSCALL_INTERRUPT_PRIORITY: ( configLIBRARY_MAX_SYSCALL_INTERRUPT_PRIORITY << (8 - configPRIO_BITS) )
-// In case of doubt mask all interrupts: 1 << (8 - BASEPRI_PRIO_BITS) i.e. 1 << 5 when 3 bits are implemented in NVIC
-// or define SEGGER_RTT_LOCK() to completely disable interrupts.
-//
