Added links to the other orgs (although the comparisons doesn't work yet, since there's only one comparison, I think?)

+🤗 Evaluate provides access to a wide range of evaluation tools. It covers a range of modalities such as text, computer vision, audio, etc. as well as tools to evaluate models or datasets. 
+
+It has three types of evaluations:
+- **Metric**: measures the performance of a model on a given dataset, usually by comparing the model's predictions to some ground truth labels -- these are covered in this space.
+- **Comparison**: used useful to compare the performance of two or more models on a single test dataset., e.g. by comparing their predictions to ground truth labels and computing their agreement -- covered in the [Evaluate Comparison](https://huggingface.co/spaces/evaluate-comparison) Spaces.
+- **Measurement**: for gaining more insights on datasets and model predictions based on their properties and characteristics -- covered in the [Evaluate Measurement](https://huggingface.co/evaluate-measurement) Spaces.
+
+All three types of evaluation supported by the 🤗 Evaluate library are meant to be mutually complementary, and help our community carry out more mindful and responsible evaluation!
