   Name it whatever you like and put in Redirect URLthe following : https://anilist.co/api/v2/oauth/pin
   

Assuming you have rust on your machine

cargo build --release

After it finishes compiling the binary will be located at ./target/release

3. Run this command to provide your access token, follow the instructions and make sure you are logged in to your anilist account

./manga-tui  anilist init

4. Run this command to check if everything is setup correctly

./manga-tui  anilist check

5. Now just run ./manga-tui and read manga as always, you should see your reading history being updated in your anilist account

6. The config file should be updated with a new parameter

# Whether or not downloading a manga counts as reading it on services like anilist
# values : true, false
# default : false
track_reading_when_download = false

set it to true and downloading a chapter will update your progress as well, only when downloading single chapters
