# Sync examples and details

What I've been recommending to people, is to maintain a sync command as a Message Command (`@bot.command()`) or some sort of message invoke.
Bots without the message content intent will still receive content of messages that mention them or are in DMs.

~~It's not like you can use a slash command to sync... when that command isn't synced.~~

## Syncing gotchas

There is a ratelimit on syncing global commands which add commands.
Updating commands (currently) has no ratelimit.

It is still recommended to sync your commands to a test guild before syncing them globally. Discord.py has added a helper method to do just that:
[`CommandTree.copy_global_to`](https://discordpy.readthedocs.io/en/master/interactions/api.html#discord.app_commands.CommandTree.copy_global_to)

This util is used as follows:

```python
# you have a defined Bot, with a tree and have commands added to it that are global.

guild = ctx.guild or discord.Object(id=...)  # you can use a full discord.Guild as the method accepts a Snowflake
Bot.tree.copy_global_to(guild=guild)
```
All this method does is copy your defined global commands (so ones without a `guild` or `guilds` kwarg, or without the `@app_commands.guilds()` decorator)
to the specified guild within the CommandTree.
When you use this method you **must** sync afterward still, you can refer to `when_to_sync.md` for details there.
