+# gcpfileupload
+
+gcpfileupload is a Go package that simplifies the process of uploading a file to a bucket in Google Cloud Storage.
+
+## Installation
+
+To use this package, install it using go get:
+
+```bash
+go get github.com/awmpietro/gcpfileupload
+```
+
+## Usage:
+
+First, import the package:
+
+```go
+import "github.com/awmpietro/gcpfileupload"
+```
+
+Create an instance of FileUploader:
+
+```go
+fileUpload := gcpfileupload.FileUploader{
+    Request:    r,
+    FormFile:   "file",
+    FileName:   "my-new-name",
+    BucketName: "your-google-cloud-storage-bucket-name",
+}
+```
+
+Call the Upload function:
+
+```go
+hasFile, err := fileUpload.Upload()
+```
+
+The Upload function returns:
+
+A boolean hasFile: true if there is a file to upload.
+false if not.
+
+An error:
+Returns nil if there is no error.
+Returns the error encountered during the upload process otherwise.
+
+##Configuration
+Make sure to set up the GOOGLE_STORAGE_BUCKET_NAME environment variable in your environment. This should point to the path of the Google user account key you've previously created:
+
+```yaml
+export GOOGLE_STORAGE_BUCKET_NAME=path_to_your_google_account_key.json
+```
+
+Replace path_to_your_google_account_key.json with the actual path to your Google user account key file.
+
+##Contributing
+Feel free to open issues or PRs if you find any problems or have suggestions!
