 ## Purpose
 Japh is a command line utility to help with manuevering your files
-and building project specific commands.
+and building project specific commands in the form of bash functions.
 
 ## Installation
 You will need to `source` the japh file from inside your
 `$HOME/.bashrc` wherever you have it installed.
 
+If you have the japh repo stored in `$HOME/code/japh`, for example, then
+in your bashrc file you would put:
+```
+source $HOME/code/japh/japh
+```
+Yes, that is `japh/japh`. The first `japh` is the directory, the second is the
+file that the function actually lives in.
+
 You also need to make sure that you have write access to the directory that
 japh is stored. For now, it simply puts all the commands it makes into a file
 called `cmds` in the same directory.
 
-## What is a command?
-These are functions that japh runs based on user input. I.E. changing
-directories, running build commands, etc.
+## What is a "command"?
+Commands are the functions that japh runs, these are created by the user.

+## Troubleshooting
+
+### Installation
+> When I run japh, it says it isn't found.
+
+Make sure nothing in your environment is "unsetting" the japh function. Start
+by checking your bashrc file and any files you source from there.
+
+> I'm getting an error when opening a terminal
+
+This could be several things:
+1. It could be that the version of japh you have cloned has an issue.
+    cd to the directory where japh is stored and try sourcing the file yourself
+2. You could have the wrong path when sourcing.
+    Check the path by running the source command from your home directory.
+3. You may be running the incorrect shell or version of bash
+    Ensure that you are running bash and not something like dash, mksh, zsh
+    or fish. I am using bash version 4.4.19 on windows at the time of writing
+    this.
+
+### Usage
+> japh doesn't take me to the right directory.
+
+Navigate to where japh is installed, and check the cmds file. From there you
+can check to see where the project is set to take you. BE CAREFUL EDITING THIS
+FILE, you can prevent japh from being able to work at all.
+
+> I don't know how to use vim to edit commands
+
+Vim is a command line, modal, text editor. It is a very nice tool to know, and
+many people use it as their only editor.
+
+Vim is the editor I chose to use to edit commands. This is because it is
+blocking. Vim will stop japh from running until your file is done being
+written, and then create the command once you have quite out of vim.
+I tried with emacs, and vscode and neither worked in the way that I needed it
+to for japh.
+
+For basic usage you will hit `i` to enter `insert mode`, write your command,
+hit `escape` and then type `:wq`.
