+
+## First time setup
+
+1. Make sure `python3` and `pip3` are installed in your system
+2. Grab latest `SC64.zip` package from GitHub releases
+3. Extract package contents to a folder
+4. Install requirements: `pip3 install -r requirements.txt`
+5. Run `python3 sc64.py --help` to check if requirements are installed
+6. Run `python3 sc64.py --print-state` to check if SC64 is detected
+
+---
+
+## Internal flashcart state
+
+SC64 holds some configuration after script has exit. To reset it simply run: `python3 sc64.py --reset-state`. Internal flashcart state can be checked by running: `python3 sc64.py --print-state`
+
+---
+
+## Uploading game/save
+
+`python3 sc64.py --boot rom --rom path_to_rom.n64 --save-type eeprom-4k --save path_to_save.sav`
+
+Replace `path_to_rom.n64` / `eeprom-4k` / `path_to_save.sav` with appropriate values for desired game. Check included help in script to check available save types.
+Arguments `--save-type` and/or `--save` can be ommited if game doesn't require any save.
+
+---
+
+## Downloading save
+
+`python3 sc64.py --backup-save path_to_save.sav`
+
+Replace `path_to_save.sav` with appropriate value. Specifying save type by `--save` argument isn't required when set correctly previously.
+
+---
+
+## Running 64DD games
+
+64DD games require DDIPL ROM and disk images. To run disk game type `python3 sc64.py --boot ddipl --ddipl path_to_ddipl.n64 --disk path_to_disk_1.ndd --disk path_to_disk_2.ndd --debug`.
+
+Replace `path_to_ddipl.n64` / `path_to_disk_x.ndd` with appropriate values. Argument `--disk` can be specified multiple times. Only `.ndd` disk format is supported currently. To change inserted disk press button on the back of SC64 flashcart.
+
+---
+
+## Direct boot option
+
+If booting game through included bootloader isn't a desired option then flashcart can be put in special mode that ommits this step.
+Run `python3 sc64.py --boot direct --rom path_to_rom.n64` to disable bootloader during boot and console reset. By default only games with 6102/7101 CIC chips will boot correctly. To change this use `--cic-params 0,0,0x3F,0x12345678ABCD` argument with appropriate values. Refer to included help in script for values meaning.
+
+---
+
+## Debug terminal
+
+`sc64.py` supports UNFLoader protocol and has same functionality implemented as desktop program. Use argument `--debug` to activate it.
+
+---
+
+## Firmware backup/update
+
+To download and backup current version of SC64 firmware run `python3 sc64.py --backup-firmware sc64_backup.upd`.
+
+To update SC64 firmware run `python3 sc64.py --update-firmware sc64.upd`
