By clicking the “remix” button, you’ll be taken to the “Create a remix” page. Remix block button Once here, you’ll be able to 1) edit YAML configuration for the block and 2) change name, description, icon, etc. Clicking “Create block” will make this block available for use in an agent. ## How to Create a Block from Scratch To create a block from scratch, you will need to click “New block” in the top bar. New block button After filling out information on the block, you will want to create a block following the `config.yaml` [reference documentation](/reference). Refer to examples of blocks on [hub.gourmand.dev](https://hub.gourmand.dev/explore/models) and visit the [YAML Reference](/reference#complete-yaml-config-example) docs for more details. New block page ### Block Inputs Blocks can receive values, including secrets, as inputs through templating. For values that the user of the block needs to set, you can use template variables (e.g. `${{ inputs.API_KEY}}`). Then, the user can set `API_KEY: ${{ secrets.MY_API_KEY }}` in the `with` clause of their agent. **Choosing between `secrets.` and `inputs.`** When creating blocks for the hub: * Use `${{ inputs.INPUT_NAME }}` in your block definition when you want users to be able to customize which secret is used * Users will then map their own secrets using `${{ secrets.SECRET_NAME }}` in the `with` clause For personal or single-use configurations, you can skip the inputs layer and reference `${{ secrets.SECRET_NAME }}` directly in your block.
