-## Examples
+## Core code
 
-Two simple examples runs out-of-the box. Those are a good basis for understanding the API of `modl` estimators.
-  - ADHD (rfMRI) sparse decomposition, relying on [nilearn](https://github.com/nilearn/nilearn)
-  ```
-  python examples/adhd_decompose.py
-  ```
-  - Movielens (User/Movie ratings) prediction
-   ```
-  python examples/recsys_predict.py
-  ```
-
-For Movielens example, you will need to download the dataset, from [spira repository](https://github.com/mblondel/spira).
-```
-make download-movielens10m
-```
+The package essentially provides three estimators:
 
-## Experiments
+- `DictFact`, that computes a matrix factorization from Numpy arrays
+- `fMRIDictFact`, that computes sparse spatial maps from fMRI images
+- `ImageDictFact`, that computes a patch dictionary from an image
+- `RecsysDictFact`, that allows to predict score from a collaborative filtering approach
 
-### Recommender systems
 
-Recommender systems experiments can be reproduced running the following command in the root repository.
+## Examples
+
+### fMRI decomposition
+
+A fast running example that decomposes a small dataset of resting-fmri data into a 70 components map is provided
 
 ```
-python examples/experimental/recsys/recsys_compare.py
+python examples/recsys_compare.py
 ```
 
-You will need to download datasets beforehand:
+It can be adapted for running on the 2TB HCP dataset, by changing the source parameter into 'hcp' (you will need to download the data first)
+
+### Hyperspectral images
+
+A fast running example that extracts the patches of a HD image can be run from
 
 ```
-make download-movielens1m
-make download-movielens10m
-make download-netflix
+python examples/decompose_image.py
 ```
 
-### HCP decomposition
+It can be adapted to run on AVIRIS data, changing the image source into 'aviris' in the file.
+
+### Recommender systems
 
-You will need to retrieve the S500 release of the [HCP dataset](http://www.humanconnectome.org/data/) in some way
- beforehand. You may use the public S3 bucket, order filled hard-drives, or download it directly.
+Our core algorithm can be run to perform collaborative filtering very efficiently:
 
-Edit `$HCPLOCATION` in the `Makefile` and run
 ```
-make hcp
+python examples/recsys_compare.py
 ```
-to create symlinks and download a useful mask.
 
-The HCP experiment can be reproduced as such:
+You will need to download datasets beforehand:
+
 ```
-# unmask data
-python examples/experiment/fmri/hcp_prepare.py
-# compare methods
-python examples/experiment/fmri/hcp_compare.py
-# analyse convergence
-python examples/experiment/fmri/hcp_analysis.py
-# plot results
-python examples/experiment/fmri/hcp_plot.py
+make download-movielens1m
+make download-movielens10m
 ```
 
-By default, results will be available in `$HOME/output/modl`
+## Future work
 
+- `sacred` dependency will be removed
+- Release a fetcher for HCP from S3 bucker
+- Release examples with larger datasets and benchmarks
