### Synchronizing all Git repositories
-Clone this repository if needed
-
-```
-git clone https://github.com/apache/sling-aggregator.git
-cd sling-aggregator
-```
-
Initialise the local repo checkout and synchronise all git repositories. The commands below must be run in the sling-aggreator git checkout.
```
$ repo init --no-clone-bundle -u https://github.com/apache/sling-aggregator.git
-$ repo sync --no-clone-bundle
+$ repo sync --no-clone-bundle -j 16
```
The output is a flat list of all Sling modules.
-### Speeding up sync
-
-Syncing all Sling modules can take a while, so if your network is fast enough you can try using multiple jobs in parallel. To use 16 jobs, run
-
-```
-$ repo sync -j 16
-```
+The `-j 16` flag instructs repo to run 16 parallel checkout jobs and is added for performance reasons only.
