+
+## Installation
+
+The following instructions assumes you have a Nintendo Switch running Atmosphère, updated to at least the latest stable version.
+Copy the `atmosphere`, and `switch` folders at the root of your sdcard, overwriting files if prompted. Also copy the `config` folder if you're not updating, to include default settings.
+
+**Note:** sys-clk-overlay requires to have [Tesla](https://gbatemp.net/threads/tesla-the-nintendo-switch-overlay-menu.557362/) installed and running
+
+## Relevant files
+
+* Config file allows one to set custom clocks per docked state and title id, described below
+
+	`/config/sys-clk/config.ini`
+
+* Log file where the logs are written if enabled
+
+	`/config/sys-clk/log.txt`
+
+* Log flag file enables log writing if file exists
+
+	`/config/sys-clk/log.flag`
+
+* CSV file where the title id, profile, clocks and temperatures are written if enabled
+
+	`/config/sys-clk/context.csv`
+
+* sys-clk overlay (accessible from anywhere by invoking the [Tesla menu](https://gbatemp.net/threads/tesla-the-nintendo-switch-overlay-menu.557362/))
+
+	`/switch/.overlays/sys-clk-overlay.ovl`
+
+* sys-clk core sysmodule
+
+	`/atmosphere/contents/00FF0000636C6BFF/exefs.nsp`
+	`/atmosphere/contents/00FF0000636C6BFF/flags/boot2.flag`
+
+## Config
+
+Presets can be customized by adding them to the ini config file located at `/config/sys-clk/config.ini`, using the following template for each app
+
+```
+[Application Title ID]
+docked_cpu=
+docked_gpu=
+docked_mem=
+handheld_charging_cpu=
+handheld_charging_gpu=
+handheld_charging_mem=
+handheld_charging_usb_cpu=
+handheld_charging_usb_gpu=
+handheld_charging_usb_mem=
+handheld_charging_official_cpu=
+handheld_charging_official_gpu=
+handheld_charging_official_mem=
+handheld_cpu=
+handheld_gpu=
+handheld_mem=
+governor_config=
+```
+
+* Replace `Application Title ID` with the title id of the game/application you're interested in customizing.
+A list of games title id can be found in the [Switchbrew wiki](https://switchbrew.org/wiki/Title_list/Games).
+* Frequencies are expressed in mhz, and will be scaled to the nearest possible values, described in the clock table below.
+* If any key is omitted, value is empty or set to 0, it will be ignored, and stock clocks will apply.
+* If charging, sys-clk will look for the frequencies in that order, picking the first found
+	1. Charger specific config (USB or Official) `handheld_charging_usb_X` or `handheld_charging_official_X`
+	2. Non specific charging config `handheld_charging_X`
+	3. Handheld config `handheld_X`
+
+### Example 1: Zelda BOTW
+
+* Overclock CPU when docked or charging
+
+Leads to a smoother framerate overall (ex: in the korok forest)
+
+```
+[01007EF00011E000]
+docked_cpu=1224
+handheld_charging_cpu=1224
+handheld_mem=1600
+```
+
+### Example 2: Picross
+
+* Underclocks on handheld to save battery
+
+```
+[0100BA0003EEA000]
+handheld_cpu=816
+handheld_gpu=153
+```
+
+### Advanced
+
+The `[values]` section allows you to alter timings in sys-clk, you should not need to edit any of these unless you know what you are doing. Possible values are:
+
+| Key                      | Desc                                                                          | Default   |

+|**charging_limit_perc**   | Charging limit (20% - 100%)                                                   | 100%(OFF) |
+|**governor_experimental** | CPU & GPU frequency governor (Experimental)                                   | OFF       |

 Чому бажано відкатити емунанд? На 21.0.0 можуть працювати не всі моди та переклади для ігор, через зменшений розмір вільної пам'яті в системі

+Також нагадую, що для коректної роботи програм та модулів на Atmosphere 1.10.0, що встановлена в цьому релізі, вони мають бути перезібрані з ісходників, або [пропатчені](https://hbpatcher.alula.me/).
