 :seedling: On 4 records, MKBDR asserted 2 records with a faulty taxonomy. Faulty taxonomy means that the name of the species is unknown in NCBI taxonomy. So it is impossible to use these records in a reference database. We will need to curate their taxonomy to validate these records.
 
-## 2. Curation 
+## 2. Curation generation 
 
-The module **[curegen](https://gitlab.mbb.univ-montp2.fr/edna/custom_reference_database/-/wikis/Curegen)** produces a [curation CSV file](https://gitlab.mbb.univ-montp2.fr/edna/custom_reference_database/-/wikis/Files-definition)
+The module **[curegen](https://gitlab.mbb.univ-montp2.fr/edna/custom_reference_database/-/wikis/Curegen)** produces a [curation CSV file](https://gitlab.mbb.univ-montp2.fr/edna/custom_reference_database/-/wikis/Files-definition). This curation file will be helpful later to apply curation on faulty records.
 
+**curegen** needs the faulty taxonomy FASTA records file as input and will output a corresponding curation file.
 
+Shortly, **curegen** seeks synonyms of the faulty species name into NCBI for each records. If no synonym is found, then it seeks in global databases a the closest genus name related to NCBI taxonomy. By default the consulted global database is 'Fishbase' but let's consult 'Catalogue of Life' instead:
+
+```
+mkbdr curegen --fasta res_raw_faulty_taxon.fasta
+--database_globalnames 'Catalogue of Life' \
+--output_prefix res_raw 
+```
+
+This will output:

+
+* `res_raw_curation.csv`: a CSV file with instructions to cure taxonomies (2 records)
+
+As we can read, on 2 faulty taxonomy records, a NCBI synonym was found for one, and for the other a genus name has been identified from the Catalogue of Life that can be used in NCBI.
+
+
+:seedling: We generated taxonomy curation instructions for the 2 faulty taxonomy records. Next step will apply this curation on records.
+
+
+## 3. Validate and curate
+
+It is possible to apply taxonomy curation with the **validate** module using `--curate` option. The inputs are:
+
+* `raw.fasta`
+* `res_raw_curation.csv`
+
+To apply taxonomy curation only for NCBI synonyms:
+
+```
+mkbdr validate --fasta raw.fasta \
+--curate res_raw_curation.csv \
+--output_prefix res_curated
+```
+
+This outputs:
+
+```
+Validate records...
+Loading local NCBI taxonomy...done.
+Curating records with faulty taxonomy...
+curation not performed on record YCA_R0449;
+On 2 faulty records, 1 records are curated.
+4 processed records.
+On these records, 3 are valid, 0 are faulty format and 1 are faulty taxon.
+```
+
+The faulty taxonomy records for which a NCBI synonym was found is curated. So that 3 valid records are produced. The faulty species name has been replaced by its NCBI synonym.
+
+* `res_curated_faulty_format.fasta`: a FASTA file with faulty format records (empty in this example)
+* `res_curated_faulty_taxon.fasta`: a FASTA file with faulty taxonomy records (1 faulty record in this step)
+* `res_curated_valide.fasta`: a FASTA file with correct records that can be use as reference database for taxonomic assignment (3 valid records in this step)
 
 
-mkbdr curegen --database_globalnames 'Catalogue of Life' --output_prefix res_raw --fasta res_raw_faulty_taxon.fasta
+:seedling: Using `--curate` option, it is possible to apply curation on faulty taxonomy records. Nevertheless, curation is not complete as one faulty records remains. This one requires to add nodes to the NCBI taxonomy tree itself.
 
-mkbdr validate --fasta tests/data/raw.fasta --curate res_raw_curation.csv --output_prefix res_curated
+## 4. Load a local NCBI taxonomy
 
+In order to produce a custom NCBI taxonomy tree, we will need to download and decompress the NCBI taxdump
+
+```
 mkbdr init_ncbi_taxdump --folder_path customtaxonomy/ --decompress
+```
+
+This will output:
+
+```
+citations.dmp
+delnodes.dmp
+division.dmp
+gencode.dmp
+merged.dmp
+names.dmp
+nodes.dmp
+gc.prt
+readme.txt
+NCBI taxdump initialisation successful !
+Path: customtaxonomy/
+```
+
+The NCBI taxonomy files are stored in the local folder `customtaxonomy/`
+
+
+:seedling: The local NCBI taxonomy will be useful for the next step as we need to edit NCBI taxonomy in order to add new taxon group.
+
+
+## 5. Validate, curate and edit local taxonomy
+
+MKBDR can edit local taxonomy with the option `--ncbi_taxonomy_edition`.
+
+```
+mkbdr validate --fasta raw.fasta \
+--curate res_raw_curation.csv \
+--ncbi_taxonomy_edition  customtaxonomy/ \
+--output_prefix res_taxo_curated
+```
+
+
+This will output:
+
+```
+Validate records...
+Loading local NCBI taxonomy...done.
+Curating records with faulty taxonomy...
+Editing ncbi_taxdump files...done.
+1 new nodes have been added in customtaxonomy/nodes.dmp and customtaxonomy/names.dmp.
+On 2 faulty records, 2 records are curated.
+4 processed records.
+On these records, 4 are valid, 0 are faulty format and 0 are faulty taxon.
+```
+The local taxonomy located on `customtaxonomy/` has been edited and all the faulty taxonomy records are curated.
+
+:seedling: Finally the following files constitute our reference database:
+
+* `res_taxo_curated_valide.fasta`: a FASTA file with correct records that can be use as reference database for taxonomic assignment (4 valid records in this step)
+* `customtaxonomy`: custom NCBI taxonomy
+
+
+## 6. Test the custom reference database
+
+We will use 
 
-mkbdr validate --fasta tests/data/raw.fasta  --curate res_raw_curation.csv --ncbi_taxonomy_edition  customtaxonomy/ --output_prefix res_taxo_curated
