+GROWI is a Wiki for Individuals and Corporations | A knowledge base tool.
+Knowledge in companies, university laboratories, and clubs can be easily shared and anyone can edit the page.
+
+We can easily write what we know and edit it together, we can **simplify the tacit knowledge (knowledge which is hard to explain with words) in our team**.  
+Let's increase the information exchange everyday.
+
+### :beginner: How to create a simple page
+
+- Start from "**Create**" button on the upper right, or the **Pencil Icon** on the lower right.
+    - The page title can be edited again later, don't worry about the title.
+        - On title input field, it's possible to create the page's hierarchy with half-width `/` (slash).
+        - （Example）Try entering `/category1/category2/page-title-we-want-to-create`.
+- We can create a bullet point by adding `-`  at the beginning of the line.
+- We can also copy and paste, drag and drop attachments such as images, PDF, Word/Excel/PowerPoint, etc.
+- Once we finished, press the "**Update**" button to publish the page.
+    - We can also save it by `Ctrl(⌘) +S`.
+
