-### Embeddings
-
-<details>
-
-The embedding endpoint is experimental and enabled only if the model is configured with `embeddings: true` in its `yaml` file, for example:
-
-```yaml
-name: text-embedding-ada-002
-parameters:
-  model: bert
-embeddings: true
-```
-
-There is an example available [here](https://github.com/go-skynet/LocalAI/tree/master/examples/query_data/).
-
-Note: embeddings is supported only with `llama.cpp` compatible models and `bert` models. bert is more performant and available independently of the LLM model.
-
-</details>
-
-### Transcriptions endpoint
-
-<details>
-
-Note: requires ffmpeg in the container image, which is currently not shipped due to licensing issues. We will prepare separated images with ffmpeg. (stay tuned!)
-
-Download one of the models from https://huggingface.co/ggerganov/whisper.cpp/tree/main in the `models` folder, and create a YAML file for your model:
-
-```yaml
-name: whisper-1
-parameters:
-  model: whisper-en
-```
-
-The transcriptions endpoint then can be tested like so:
-```

 It loosely follows [the quickstart](https://gpt-index.readthedocs.io/en/stable/guides/primer/usage_pattern.html).
 
-Summary of the steps:
-
-- prepare the dataset (and store it into `data`)
-- prepare a vector index database to run queries on
-- run queries
-
 ## Requirements
 
-You will need a training data set. Copy that over `data`.
+For this in order to work, you will need a model compatible with the `llama.cpp` backend. This is will not work with gpt4all.
+
+The example uses `WizardLM`. Edit the config files in `models/` accordingly to specify the model you use (change `HERE`).
+
+You will also need a training data set. Copy that over `data`.
