156156Channel members reach the same field for the channel scope through the **Configure** page, linked in the footer of any Claude reply in the channel, without going through admin settings. Both entry points write the same instructions, so a change from either place is visible in the other.

158To let a central team write a channel's instructions from its own Slack channel, see [Manage a channel's instructions from another channel](https://claude.com/docs/claude-tag/admins/managed-by.md).

160158#### Instruction format
161159
162160The field is plain text, inserted as written; there is no include or template syntax, and `{{include:...}}` is passed through literally. To give Claude a repository's `CLAUDE.md`, [grant the repository](https://claude.com/docs/claude-tag/admins/configure-github.md#grant-repository-access) and name it in the request; its `CLAUDE.md` loads after the clone completes.

164162#### What Claude reads in a channel
165163
166What Claude reads in a channel is the concatenated custom instructions of its scope chain, the instructions of each bundle that applies there, the channel's [managed instructions](https://claude.com/docs/claude-tag/admins/managed-by.md#how-managed-instructions-load) if another channel manages it, and the `CLAUDE.md` of any repository it clones. Projects in claude.ai don't apply here; Claude doesn't read a Project's instructions or knowledge in Slack, and a channel can't be pointed at a Project.
