 To exclude repositories, update your config typing:

+
+Configuration
+-------------
+
+Buse will check if a file `.buse.yml` exists in the current directory.
+Note: You can use the `--config` (ie. `buse status --config ~/my-dir`) option to change the directory of the config file.
+
+A basic `.buse.yml` looks like:
+```yaml
+global:
+    ignore_repositories:
+        - workshop-serializer-todo
+        - twgit
+
+datatheke:
+    repositories:
+        datatheke: '[email protected]:datatheke/datatheke.git'
+        datatheke-cli: '[email protected]:datatheke/datatheke-cli.git'
+
+buse:
+    repositories:
+        buse: '[email protected]:iamluc/buse.git'
+
+other:
+    repositories:
+        super-project: ~
 ```
 
+The `global` section contains the global configuration of buse.
+
+Others sections are called "groups".
+
+If you call buse with the `--group` option (ie. `buse status --group datatheke --group buse`),
+the command will be executed only for the repositories defined in the selected groups.
+
+Without any `--group` option, buse will search all git repositories in the working directory.
