+
+The Docker Compose binary. You use this command to build and manage multiple services in Docker containers.
+
+Use the `-f` flag to specify the location of a Compose configuration file. This
+flag is optional. If you don't provide this flag. Compose looks for a file named
+`docker-compose.yml` in the  working directory. If the file is not found,
+Compose looks in each parent directory successively, until it finds the file.
+
+Use a `-` as the filename to read configuration file from stdin. When stdin is
+used all paths in the configuration are relative to the current working
+directory.
+
+Each configuration can has a project name. If you supply a `-p` flag, you can specify a project name. If you don't specify the flag, Compose uses the current directory name.
