+Git Large File Storage ('LFS') needs to change your `~/.gitconfig` to check out those binary files:
 
-```bash

+Then track some filetypes with:
 
-```bash
-git lfs track "\*.ttf"
+```sh

 ```
 
 Or a directory with:

+Track the changes to `.gitattributes`:

+## Bash Completion
+
+If bash completion does not work, you'll have to add it:
+
+```sh
+git lfs completion bash |  sudo tee /usr/share/bash-completion/completions/git-lfs 
+```
+
+## Trouble Shooting
+
+You have some file "$FILE".png, which has some problem.
+
+Check the filetype:
+
+```sh
+file "$FILE".png
+```
+
+This should say the type is 'image'.
+If it says the type is 'text', then this file is really just a reminder to `git-lfs` to check out that file.
+
+Check `git-lfs` is expecting that file:
+
+```sh
+git lfs status
+git lfs ls-files
+```
+
+...then try these commands, and check the filetype again:
+
+```sh
+git lfs fetch --all
+git lfs fsck
+git lfs checkout
+git lfs status
+```
