 ## Adding new documentation
 
-_Instructions forthcoming on how to find the right place to add your docs._
+As outlined in [this IA issue](https://github.com/AlexsLemonade/OpenScPCA-analysis/issues/61), we have several sections of documentation.
+The diagram below shows the directory structure for the docs, for now considering only the top three directory levels.
+The directory names as written in the IA issue are shown in parentheses.
 
-Files and directories should be named with all lowercase letters using `-`, not `_`, where needed.
+Each bold bullet point in the IA issue is a directory, and each plain-text bullet is a markdown file.
+Consult the IA issue and this directory structure to determine where to place new markdown file.
+
+If the IA indicates this file should be in an even more nested directory, don't worry about it for now; later, we will add additional nested directores as more documentation comes together.
+
+Files and directories should be named with all lowercase letters and use `-`, not `_`, where needed.
 **Be sure to consult the [style guide](./general-style-guide.md) when writing your documentation.**
