 * If the contribution contains multiple commits, are they grouped together into logical changes (one major change per pull request)?

 ## Compiling the Project
 
-`idf.py build`
+`make -j4 all`
 
 ... will compile app, bootloader and generate a partition table based on the config.
 
+NOTE: The `-j4` option causes `make` to run 4 parallel jobs. This is much faster than the default single job. The recommended number to pass to this option is `-j(number of CPUs + 1)`.
+
 ## 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:
 
-`idf.py -p PORT flash`
+`make -j4 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`.

 ## 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 the ESP32. 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).

 Exit the monitor by typing Ctrl-].
 
 To build, flash and monitor output in one pass, you can run:
 
-`idf.py flash monitor`
+`make -j4 flash monitor`
 
 ## Compiling & Flashing Only 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 any source files have changed.
 
 (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 the number of CPU cores in your system, plus one.)
+
+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/en/api-guides/partition-tables.rst`](docs/en/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`.
+The `make 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 `make erase_flash`.
 
-This can be combined with other targets, ie `idf.py -p PORT erase_flash flash` will erase everything and then re-flash the new app, bootloader and partition table.

+// In case of doubt mask all interrupts: 1 << (8 - BASEPRI_PRIO_BITS) i.e. 1 << 5 when 3 bits are implemented in NVIC

+       help
+           If not set (default), app partition size must be a multiple of 64KB. App images are padded to 64KB length, and the bootloader checks any trailing bytes after the signature (before the next 64KB boundary) have not been written. This is because flash cache maps entire 64KB pages into the address space. This prevents an attacker from appending unverified data after the app image in the flash, causing it to be mapped into the address space.
+
+           Setting this option allows the app partition length to be unaligned, and disables padding of the app image to this length. It is generally not recommended to set this option, unless you have a legacy partitioning scheme which doesn't support 64KB aligned partition lengths.
