Create a tag for your WordPress plugin in the SVN repository

Using your terminal/command line on linux or mac.

Change to your plugin directory (`cd`).
Copy the trunk into your tags directory where “1.0.4” should be changed to your current stable version.
```
svn cp trunk tags/1.0.4
```
If you are using a GIT repository within your SVN repository, delete the GIT files.
```
ls -a tags/1.0.4
rm -rf tags/1.0.4/.git*
rm tags/1.0.4/README.md
```
