 # SEAL db - Simple, Efficient And Lite database for NGS
 
+![seal.gif](docs/img/seal.gif)
+
+SEAL db is a Python project that provides a simple, efficient, and lightweight
+database for Next Generation Sequencing (NGS) data. SEAL db is built with the
+Flask framework and uses PostgreSQL as the backend database. It includes a web
+interface that allows users to upload and query NGS data.
+
+__Please report any issue [here](https://github.com/mobidic/SEAL/issues/new)__
+
 ## Installation
 
-First of all clone the repo :
+To install SEAL db, first clone the repository from GitHub:
+
 ```bash
 git clone https://github.com/mobidic/seal.git
 ```
 
+SEAL db requires several dependencies to be installed, which can be done either
+with Conda or manually.
+
 ### Install dependencies
 
 #### With Conda
 
-Please install conda ([documentation here](https://docs.conda.io/projects/conda/en/latest/user-guide/install/index.html))
+To install dependencies with Conda, first install Conda if it is not already installed. Conda installation instructions can be found ([here](https://docs.conda.io/projects/conda/en/latest/user-guide/install/index.html))
+
+After installing Conda, create a new environment using the environment.yml file
+provided with SEAL db:
 
 `conda env create -f environment.yml`
 
-#### VEP
+#### Installing VEP
 
 > __If you have install all dependencies from conda you need to activate your
-environment by launching this command :__ `conda activate seal`
+environment by launching this command:__ `conda activate seal`
 
-You need to complete VEP installation (https://www.ensembl.org/info/docs/tools/vep/script/vep_download.html#installer) :
-`vep_install -a cf -s homo_sapiens -y GRCh37 -c /output/path/to/GRCh37/vep --CONVERT`
+After installing dependencies, you need to install VEP (Variant Effect
+Predictor), which is used by SEAL db to annotate variants. The installation
+instructions for VEP can be found
+[here](https://www.ensembl.org/info/docs/tools/vep/script/vep_download.html#installer).
+
+For conda environment:
 
-##### Plugins
+`vep_install -a cf -s homo_sapiens -y GRCh37 -c /output/path/to/GRCh37/vep --CONVERT`
 
-Install VEP plugins (https://www.ensembl.org/info/docs/tools/vep/script/vep_plugins.html) :
+After installing VEP, you need to install several VEP plugins that are used by
+SEAL db:
   - dbNSFP
   - MaxEntScan
   - SpliceAI
   - dbscSNV
   - GnomAD
 
+The installation instructions for VEP plugins can be found ([here](https://www.ensembl.org/info/docs/tools/vep/script/vep_plugins.html)).
+
 *__A more complete guide will be written soon__*
 
-### Configuration of the app
+### Configuration
+
+After installing dependencies and VEP, you need to configure the app by editing
+two files:
+- `seal/static/vep.config.json`
+- `seal/config.yaml`
 
-- Please edit file `seal/static/vep.config.json` and replace those variable:
-  - `{dir_vep}` => `/path/to/vep`
-  - `{dir_vep_plugins}` => `/path/to/vep/plugins`
-  - `{GnomAD_vcf}` => `/path/to/gnomad.vcf`
-  - `{fasta}` => `/path/to/genome.fa.gz`
+In `seal/static/vep.config.json`, replace the following variables with the appropriate paths:
+- `{dir_vep}` => `/path/to/vep`
+- `{dir_vep_plugins}` => `/path/to/vep/plugins`
+- `{GnomAD_vcf}` => `/path/to/gnomad.vcf`
+- `{fasta}` => `/path/to/genome.fa.gz`
 
-- Please edit file `seal/config.yaml` :
-  - create your secret app key.
-  - you can edit following what you need
+In `seal/config.yaml`, create your secret app key and edit other settings as
+needed.
