-- [ ] Find relevant datasets for medical domain
-- [ ] Find relevant "CLIP" models for medical domain
-- [ ] Compute embeddings across datasets and models for medical and store them
-- [ ] Evaluate each model on each dataset based on the `evaluation` module in this repo
+Welcome to `clip-eval`, a repository for evaluating text-to-image models like CLIP, SigLIP, and the like.
 
-- Repeat for geospatial and sports analytics
+Evaluate machine learning models against a benchmark of datasets to assess their performance on the generated embeddings, and visualize changes in embeddings from one model to another within the same dataset.
 
-### Set up the development environment
+## Installation
 
-1. Create the virtual environment, add dev dependencies and set up pre-commit hooks.
+> `clip-eval` requires [Python 3.11](https://www.python.org/downloads/release/python-3115/) and [Poetry](https://python-poetry.org/docs/#installation).
+
+1. Clone the repository:
    ```
-   ./dev-setup.sh
+   git clone https://github.com/encord-team/text-to-image-eval.git
    ```
-2. Add environment variables:
+2. Navigate to the project directory:
+   ```
+   cd text-to-image-eval
+   ```
+3. Install the required dependencies:
+   ```
+   poetry shell
+   poetry install
    ```
-   export CLIP_CACHE_PATH=$PWD/.cache
-   export OUTPUT_PATH=$PWD/output
+4. Add environment variables:
+   ```
+   export CLIP_EVAL_CACHE_PATH=$PWD/.cache
+   export CLIP_EVAL_OUTPUT_PATH=$PWD/output
    export ENCORD_SSH_KEY_PATH=<path_to_the_encord_ssh_key_file>
-   export ENCORD_CACHE_DIR=$PWD/.cache/encord
    ```
 
-### CLI Interface
+## Usage
+
+### Embeddings generation
+
+To build embeddings, run the CLI command `clip-eval build`.
+This commands allows you to interactively select the model and dataset combinations on which to build the embeddings.
+
+Alternatively, you can choose known (model, dataset) pairs using the `--model-dataset` option. For example:
+```
+clip-eval build --model-dataset clip/plants
+```
+
+### Model evaluation
 
-Basic CLI interface available with:
+To evaluate models, use the CLI command `clip-eval evaluate`.
+This command enables interactive selection of model and dataset combinations for evaluation.
 
-```shell
-clip-eval [command]
+Alternatively, you can specify known (model, dataset) pairs using the `--model-dataset` option. For example:
+```
+clip-eval evaluate --model-dataset clip/plants
 ```
 
-### [DEPRECATED] Commands I used to run different bits of the code
+### Embeddings animation
+
+To create a 2D animation of the embeddings, use the CLI command `clip-eval animate`.
+This command allows to visualise the reduction of embeddings from two different models on the same dataset.
+
+The animations will be saved at the location specified by the environment variable `CLIP_EVAL_OUTPUT_PATH`.
+By default, this path corresponds to the repository directory.
