 # gitclean
 Guided Branch Cleanup Utility
+
+
+# Install
+
+`go get -u github.com/MCBrandenburg/gitclean`
+
+# Configuration
+
+You can set standard branches to be ignored using the environment variable `GITCLEAN_IGNORE`
+
+Example:
+
+```
+GITCLEAN_IGNORE=master,development
+```
+
+# Usage
+In the root of the project you want to clean, enter this in your prompt: `gitclean`
+
+
+## Delete Branches
+```
+❰~/g/s/g/M/test(OK test3)❱(0)≻ git branch -l
+  development
+  master
+  test1
+  test2
+* test3
+❰~/g/s/g/M/test(OK test3)❱(0)≻ gitclean
+GITCLEAN_IGNORE set to 'master,development'
+Remove branch test1[y,N,q]? y
+Remove branch test2[y,N,q]? n
+The following branches will be deleted:
+	test1
+Continue [y,N]? y
+	removing test1
+Exiting
+❰~/g/s/g/M/test(OK test3)❱(0)≻ git branch -l
+  development
+  master
+  test2
+* test3
+❰~/g/s/g/M/test(OK test3)❱(0)≻
+```
+
+## Quit During Branch Selection
+```
+❰~/g/s/g/M/testquit(OK test3)❱(0)≻ git branch -l
+  development
+  master
+  test1
+  test2
+* test3
+❰~/g/s/g/M/testquit(OK test3)❱(0)≻ gitclean
