 # HPO
 
-This library is a Rust implementation of [PyHPO](https://pypi.org/project/pyhpo/).
-
-## What is this?
-
 HPO, the [Human Phenotype Ontology](https://hpo.jax.org/app/) is a standard vocabulary of phenotypic abnormalities in human diseases. It is an Ontology, so all terms are connected to each other, similar to a directed graph.  
 
 This library provides convenient APIs to work with the ontology. The main goals are to compare terms - or sets of terms - to each other and run statistics for enrichment analysis.
 
+This library is basically a Rust implementation of [PyHPO](https://pypi.org/project/pyhpo/), but contains some additional features as well.
+
+
 ### Features
-- Calculate the similarity of HPO terms
-- Calculate the similarity of multiple sets of HPO terms (e.g. a patient's clinical information)
-- Enrichment analysis of genes and diseases in sets of HPO terms
-- Compare different HPO versions
-- Graph based analysis of the ontology
+
+- 👫 Identify patient cohorts based on clinical features
+- 👨‍👧‍👦 Cluster patients or other clinical information for GWAS
+- 🩻→🧬 Phenotype to Genotype studies
+- 🍎🍊 HPO similarity analysis
+- 🕸️ Graph based analysis of phenotypes, genes and diseases
+- 🔬 Enrichment analysis of genes and diseases in sets of HPO terms
 - Completely written in Rust, so it's **🚀blazingly fast🚀**<sup>TM</sup> ([Benchmarks](#benchmarks))
 
+
 ## What is the current state?
 
 The library is pretty much feature-complete, at least for my use-cases. If you have any feature-requests, please open an Issue or get in touch. I'm very much interested in getting feedback and new ideas what to improve.

-HPO data must be downloaded first from  [Jax HPO](https://hpo.jax.org/) itself. You need the following files:
-- [phenotype.hpoa](https://hpo.jax.org/app/data/annotations) available as "Download HPO annotations" (Required to connect `OmimDisease` to `HpoTerm`s
-- [genes_to_phenotype.txt](https://hpo.jax.org/app/data/annotations) available as "Genes to Phenotype" (Required to connect `Gene` to `HpoTerm`)

-2. Or it can be converted to a localy binary by copy  `examples/obo_to_bin.rs` into your project, then run 
-```sh
-cargo run --example --release obo_to_bin <PATH TO FOLDER WITH JAX DATA> <OUTPUT FILENAME>`

 ## Benchmarks
+
 As the saying goes: "Make it work, make it good, make it fast". The *work* and *good* parts are realized in [PyHPO](https://pypi.org/project/pyhpo/). And even though I tried my best to make it *fast*, I was still hungry for more. So I started developing the `hpo` Rust library in December 2022. Even without micro-benchmarking and tuning performance as much as I did for `PyHPO`, `hpo` is indeed much much faster already now.
 
 The below benchmarks were run non scientificially and your mileage may vary. I used a MacBook Air M1, `rustc 1.68.0`, `Python 3.9` and `/usr/bin/time` for timing.
