+# cli
+
+A git-compatible command-line interface that uses libgit2.
+
+## Adding commands
+
+1. Individual commands have a `main`-like top-level entrypoint.  For example:
+
+   ```c
+   int cmd_help(int argc, char **argv)
+   ```
+
+   Although this is the same signature as `main`, commands are not built as
+   individual standalone executables, they'll be linked into the main cli.
+   (Though there may be an option for command executables to be built as
+   standalone executables in the future.)
+
+2. Commands are prototyped in `cmd.h` and added to `main.c`'s list of
+   commands (`cli_cmds[]`).  Commands should be specified with their name,
+   entrypoint and a brief description that can be printed in `git help`.
+   This is done because commands are linked into the main cli.
+
+3. Commands should accept a `--help` option that displays their help
+   information.  This will be shown when a user runs `<command> --help` and
+   when a user runs `help <command>`.
