## Step 1: Commit all your changes
Before proceeding, make sure all your changes are committed, including your .gitignore file.
## Step 2: Remove everything from the repository
To clear your repo, use:
```
git rm -r --cached .
```
> rm is the remove command <br />
> -r will allow recursive removal <br />
> –cached will only remove files from the index. Your files will still be there. <br />
> The . indicates that all files will be untracked. You can untrack a specific file with git rm --cached foo.txt (thanks @amadeann). <br />
> The rm command can be unforgiving. If you wish to try what it does beforehand, add the -n or --dry-run flag to test things out.<br />
## Step 3: Re add everything
```
git add .
```
## Step 4: Commit
```
git commit -m ".gitignore fix"
```
