+For a detailed step-by-step introduction, refer to the [Getting Started](https://localai.io/basics/getting_started/index.html) guide. For those in a hurry, here's a straightforward one-liner to launch a LocalAI instance with [phi-2](https://huggingface.co/microsoft/phi-2) using `docker`:
 
-<hr>
-
-In a nutshell:
-
-- Local, OpenAI drop-in alternative REST API. You own your data.
-- NO GPU required. NO Internet access is required either
-  - Optional, GPU Acceleration is available in `llama.cpp`-compatible LLMs. See also the [build section](https://localai.io/basics/build/index.html).
-- Supports multiple models
-- 🏃 Once loaded the first time, it keep models loaded in memory for faster inference
-- ⚡ Doesn't shell-out, but uses C++ bindings for a faster inference and better performance.

-LocalAI was created by [Ettore Di Giacinto](https://github.com/mudler/) and is a community-driven project, focused on making the AI accessible to anyone. Any contribution, feedback and PR is welcome!
-
-Note that this started just as a [fun weekend project](https://localai.io/#backstory) in order to try to create the necessary pieces for a full AI assistant like `ChatGPT`: the community is growing fast and we are working hard to make it better and more stable.

-## Creating a gRPC backend
-
-LocalAI backends are `gRPC` servers.
-
-In order to create a new backend you need:
-
-- If there are changes required to the protobuf code, modify the [proto](https://github.com/go-skynet/LocalAI/blob/master/pkg/grpc/proto/backend.proto) file and re-generate the code with `make protogen`.
-- Modify the `Makefile` to add your new backend and re-generate the client code with `make protogen` if necessary.
-- Create a new `gRPC` server in `extra/grpc` if it's not written in go: [link](https://github.com/go-skynet/LocalAI/tree/master/extra/grpc), and create the specific implementation.
-    - Golang `gRPC` servers should be added in the [pkg/backend](https://github.com/go-skynet/LocalAI/tree/master/pkg/backend) directory given their type. See [piper](https://github.com/go-skynet/LocalAI/blob/master/pkg/backend/tts/piper.go) as an example.
-    - Golang servers needs a respective `cmd/grpc` binary that must be created too, see also [cmd/grpc/piper](https://github.com/go-skynet/LocalAI/tree/master/cmd/grpc/piper) as an example, update also the Makefile accordingly to build the binary during build time.
-- Update the Dockerfile: if the backend is written in another language, update the `Dockerfile` default *EXTERNAL_GRPC_BACKENDS* variable by listing the new binary [link](https://github.com/go-skynet/LocalAI/blob/c2233648164f67cdb74dd33b8d46244e14436ab3/Dockerfile#L14).
-
-Once you are done, you can either re-build `LocalAI` with your backend or you can try it out by running the `gRPC` server manually and specifying the host and IP to LocalAI with `--external-grpc-backends` or using (`EXTERNAL_GRPC_BACKENDS` environment variable, comma separated list of `name:host:port` tuples, e.g. `my-awesome-backend:host:port`):
-
-```bash
-./local-ai --debug --external-grpc-backends "my-awesome-backend:host:port" ...

 ### How do I get models? 
 
-<details>
-
 Most gguf-based models should work, but newer models may require additions to the API. If a model doesn't work, please feel free to open up issues. However, be cautious about downloading models from the internet and directly onto your machine, as there may be security vulnerabilities in lama.cpp or ggml that could be maliciously exploited. Some models can be found on Hugging Face: https://huggingface.co/models?search=gguf, or models from gpt4all are compatible too: https://github.com/nomic-ai/gpt4all.

 ### What's the difference with Serge, or XXX?

-<details>
-
 LocalAI is a multi-model solution that doesn't focus on a specific model type (e.g., llama.cpp or alpaca.cpp), and it handles all of these internally for faster inference,  easy to set up locally and deploy to Kubernetes.

 There are few situation why this could occur. Some tips are:
 - Don't use HDD to store your models. Prefer SSD over HDD. In case you are stuck with HDD, disable `mmap` in the model config file so it loads everything in memory.
@@ -38,61 +28,31 @@ There are few situation why this could occur. Some tips are:
 - Run LocalAI with `DEBUG=true`. This gives more information, including stats on the token inference speed.
 - Check that you are actually getting an output: run a simple curl request with `"stream": true` to see how fast the model is responding.

 ### Can I use it with a Discord bot, or XXX?
 
-<details>
-
 Yes! If the client uses OpenAI and supports setting a different base URL to send requests to, you can use the LocalAI endpoint. This allows to use this with every application that was supposed to work with OpenAI, but without changing the application!

 ### Can this leverage GPUs?

 ### Where is the webUI? 
 
-<details> 
-There is the availability of localai-webui and chatbot-ui in the examples section and can be setup as per the instructions. However as LocalAI is an API you can already plug it into existing projects that provides are UI interfaces to OpenAI's APIs. There are several already on github, and should be compatible with LocalAI already (as it mimics the OpenAI API)

 Yes, see the [examples](https://github.com/go-skynet/LocalAI/tree/master/examples/)!

 ### How can I troubleshoot when something is wrong?
 
-<details>
-
 Enable the debug mode by setting `DEBUG=true` in the environment variables. This will give you more information on what's going on.
 You can also specify `--debug` in the command line.

 ### I'm getting 'invalid pitch' error when running with CUDA, what's wrong?

 This typically happens when your prompt exceeds the context size. Try to reduce the prompt size, or increase the context size.
