# Link is NOT a Note Taking App In many note-taking Apps, we have detailed records of various aspects of the content, which are scattered knowledge points, but in fact there is a certain relationship between the content, such as the registration process to recommend the attention of the content, so the registration process and the recommended users are two knowledge points, resulting in a relationship between the registration process, we need to take into account the impact of the registration process when we make any strategic changes to recommend the attention of the time to do any strategic changes. More often than not, this relationship can only exist in our minds, and when we need to use these relationships, we can only look for them in our minds, thinking, and inevitably missing. Link hopefully can help you organize your knowledge map, organize your knowledge points, establish relationships, and do what you need to do to make your knowledge more tightly knit and get things organized. # Relationships Between Things In our complex system, there are relationships between many things. Before we do something, we need to think about what we need to do in advance to prepare for it, and after we do something, what we need to add and improve. These little things exist in our daily work, and when we really need to use them, we need to think carefully, and there may be some omissions and mistakes, so Link hopes that by linking things before the connection, when we need to see a thing, we can find the corresponding related things. # A Bad Pen is Better than a Good Memory We can build our knowledge graph as we organize our content. Create a new card that describes a point, which can be any piece of content, select cards that already exist, create pre- and subsequent relationships, and associate related content to form a knowledge network. This way, when we do subsequent projects, we can find related content through tags and search to see what needs to be prepared and added to improve. # Tag Management Add corresponding tags to each card, when related cards or need to view the knowledge, through the tags and quick search, to find the corresponding knowledge card, view the predecessor and successor relationship, sort out the content we need to do. # Detailed Content Links More detailed content in the knowledge point may exist in various notes or websites, you can add these knowledge points as attached links to our knowledge points, so that you can view more detailed content at any time. We hope that Link can help you to do a better job of managing your knowledge graph.
