+# PPanGGOLiN container
+
+Main tool: [PPanGGOLiN](https://github.com/labgem/PPanGGOLiN)
+  
+Code repository: https://github.com/labgem/PPanGGOLiN
+
+Basic information on how to use this tool:
+- executable: ppanggolin
+- help: --help
+- version: --version
+- description: |
+> PPanGGOLiN builds pangenomes through a graphical model and a statistical method to partition gene families in persistent, shell and cloud genomes.
+
+Additional information:
+
+PPanGGOLiN only creates the pangenome graphs. It is recommended to use another tool to visualize them. Please read https://github.com/labgem/PPanGGOLiN/wiki for more information.
+  
+Full documentation: https://github.com/labgem/PPanGGOLiN/wiki
+
+## Example Usage
+
+```bash
+ppanggolin annotate --fasta organisms.fasta.list --output output 
+
+# many of the commands manipulate the 'pangenome.h5' file in place
+ppanggolin cluster -p pangenome.h5
+ppanggolin graph -p pangenome.h5 
+ppanggolin partition -p pangenome.h5
+ppanggolin draw -p pangenome.h5 --ucurve   
+
+# there are some human-readable files that can be generated as well
+ppanggolin write -p pangenome.h5 --stats --output stats
+```
