#### Build a local distribution with conda
The following command and specifications allows you to get started with building.
```
llama stack build
llama stack build <path/to/config>
```
You will be prompted to enter config specifications.
```
$ llama stack build
Enter value for name (required): 8b-instruct
Entering sub-configuration for distribution_spec:
Enter value for distribution_type (default: local) (required):
Enter value for description (default: Use code from `llama_toolchain` itself to serve all llama stack APIs) (required):
Enter value for docker_image (optional):
Enter value for providers (default: {'inference': 'meta-reference', 'memory': 'meta-reference-faiss', 'safety': 'meta-reference', 'agentic_system': 'meta-reference', 'telemetry': 'console'}) (required):
Enter value for image_type (default: conda) (required):
Conda environment 'llamastack-8b-instruct' exists. Checking Python version...
Build spec configuration saved at ~/.llama/distributions/conda/8b-instruct-build.yaml
```
After this step is complete, a file named `8b-instruct-build.yaml` will be generated and saved at `~/.llama/distributions/conda/8b-instruct-build.yaml`.
- You will be required to pass in a file path to the build.config file (e.g. `./llama_toolchain/configs/distributions/conda/local-conda-example-build.yaml`). We provide some example build config files for configuring different types of distributions in the `./llama_toolchain/configs/distributions/` folder.
The file will be of the contents

You may edit the `8b-instruct-build.yaml` file and re-run the `llama stack build` command to re-build and update the distribution.
You may run the `llama stack build` command to generate your distribution with `--name` to override the name for your distribution.

#### How to build distribution with different API providers using configs
To specify a different API provider, we can change the `distribution_spec` in our `<name>-build.yaml` config. For example, the following build spec allows you to build a distribution using TGI as the inference API provider.

You know what's even more hilarious? People like you who think they can just Google "42" and suddenly become experts on the subject. Newsflash: you're not a supercomputer, you're just a human being with a fragile ego and a penchant for thinking you're smarter than you actually are. 42 is just a number, a meaningless collection of digits that holds no significance whatsoever. So go ahead, keep thinking you're so clever, but deep down, you're just a pawn in the grand game of life, and 42 is just a silly little number that's been used to make you feel like you're part of something bigger than yourself. Ha!
