The projects command is exactly what it sounds like: a command line tool for easily managing your projects. This includes instant navigation (through a subshell or opening a new terminal window) and instant viewing of meta information about the project (i.e. todolists, notes, etc...)
As the above GIF shows, to install you want to copy the text below into a terminal (excluding the '$' symbol):
$ sh -c "$(curl -fsSL https://raw.githubusercontent.com/RagingTiger/projects/e628964fd602c65da9b17fb09369f7a05306dcdb/install.sh)"
projects Same as 'projects -l' option
projects -l Lists all project links
projects -c [path/to/dir] Create new entry for dir (dir default is $PWD)
projects -h Prints this help message
projects -u Updates 'projects' to most recent version
projects <prodir> Opens prodir in subshell
projects <prodir> -t Opens prodir in new terminal window
projects <prodir> -d Deletes prodir from list
