 # bitwarden-helper-scripts
 
+These are just some helper scripts I put together to help when using the official Bitwarden CLI. 
+
+## bwunlock.sh
+
+Used to unlock a bitwarden vault and set the appropriate environment variables to keep the vault unlocked. 
+
+### Usage Instructions
+
+1. Copy the file to a location of your choosing, I use `/home/$USER/scripts`
+
+2. Set the following alias in your `~/.bashrc`:
+```alias bw-unlock="source /home/$USER/scripts/bwunlock.sh"```
+
+3. Source your bashrc or close and re-open your shell
+
+4. Run `bw-unlock` and imput your Bitwarden Master Password when prompted
+
+5. Run any Bitwarden command to ensure the script worked, like `bw list items`
