+# git-sync
+Git-Sync helps you sync your repositories across multiple remotes.
+
+The main goal of this script is to create enough redundancy so even if a single provider will fail you can still access your code using alternative hosting companies.
+
+## How to use
+### 1. Generate SSH key
+```bash
+cd c:\Users\Alan\.ssh\
+ssh-keygen.exe
+notepad.exe id_rsa.pub
+```
+
+### 2. Add SSH keys to your alternate hosting websites
+Go to you repository hosting website and add key generated in previous step.
+
+Here are some examples:
+
+- `https://[USER_NAME].visualstudio.com/_details/security/keys`
+- `https://bitbucket.org/account/user/[USER_NAME]/ssh-keys/`
+- `https://github.com/settings/keys`
+
+### 3. Create configuration
+- Rename `config-example.json` into `config.json`
+- Add your configuration
+
+### 4. Run script
+
+```powershell
+.\sync.ps1
+```
