โ€˜a plain-text file format for todos and check listsโ€™

[x]it! (github)

Note:
[x]it! is not software. โ€œThe basic operations like creating items or checking them off can be done in every text editor.” Itโ€™s also a format developers can utilize in creating tools, app plugins, etc. which follow the specification. Cool.
