+&nbsp;
+RFSC is a Reference-Free Sequence Classification Tool that using machine learning classifiers relies on an ensemble of experts in order to provide efficient classification in metagenomic contexts.
+
+## Instalation
+
+```sh
+git clone https://github.com/cobilab/RFSC
+cd RFSC
+./RFSC.sh --install
+```
+
+## Build NCBI Reference Databases
+
+```sh
+./RFSC.sh --build-ref-virus --build-ref-bacteria --build-ref-archaea --build-ref-protozoa \ --build-ref-fungi --build-ref-plant --build-ref-mitochondrial --build-ref-plastid
+```
+
+## Running Examples
+
+##### ✨ Generate a synthetic sequence and subsequently proceed to a Reference-Free Reconstruction of the same:
+&nbsp;
+```sh
+./RFSC.sh --clean y
+./RFSC.sh --threads 8 --gen-adapters
+./RFSC.sh --efetch-fasta 155971 Input_Data/EntrezGenomes 
+./RFSC.sh --efetch-fasta EF491856.1 Input_Data/EntrezGenomes 
+./RFSC.sh --efetch-fasta MT682520 Input_Data/EntrezGenomes
+./RFSC.sh -synt Input_Data/EntrezGenomes/155971.fna Input_Data/EntrezGenomes/EF491856.1.fna Input_Data/EntrezGenomes/MT682520.fna
+./RFSC.sh -trim TT PE --run-de-novo
+```
+
+##### ✨ Reference-Based Classification, usign FALCON-meta:
+###### (If the reference databases have already been built and the Reference Free Reconstruction stage is finished)
+&nbsp;
+```sh
+./RFSC.sh --threads 8 --set-len-cov 100 3 --set-threshold-max-min 70 1 --run-falcon SO Viral
+```
+
+
+##### ✨ Reference-Free Classification, using XBoost 
+&nbsp;
+```sh
+./RFSC.sh --threads 8 --efetch-fasta 155971 RefFree
+./RFSC.sh --run-xgboost
+```
+
+## System Requirements
+
+Laptop computer running Linux Ubuntu (for example, 18.04 LTS or higher) with GCC (https://gcc.gnu.org), Conda (https://docs.conda.io) and CMake (https://cmake.org) installed. The hardware must contain at least 8 GB of RAM, and a 800 GB disk. In the case of the this, if the database is not re-built, it is only needed near 10 GB of space.
