+## Current status
+
+Currently it only implements the [Vercel Blob API](https://vercel.com/docs/storage/vercel-blob). You can use this package as a library as well as a command line utility.
+
+## Installation
+
+This package is still unreleased. You can only install it locally.
 
 ```sh
-pip install -e '.[test]'
+git clone https://github.com/misaelnieto/vercel-storage.git
+cd vercel-storage
+pip install -e .
+```
+
+### Installation in development mode
+
+Probably only useful for the author and contributors.

+## Command line usage
+
+### Configuration
+
+You must set the `BLOB_READ_WRITE_TOKEN` environment variable to be able to use the library.
+
+```sh
+export BLOB_READ_WRITE_TOKEN="vercel_blob_rw_ABC1234XYz"
+```
+
+### Put operation
+
+```sh
+vercel_storage blob upload path/to/file.zip
+```
+
+You can also print the output information as a json:
+
+```sh
+vercel_storage --json blob upload path/to/file.zip
+```
+
+### Copy operation
+
+```sh
+vercel_storage blob copy <blob url> new/file/path/file.zip
+```
 
+You can also print the output information as a json:
 
 ```sh
-BLOB_READ_WRITE_TOKEN="vercel_blob_rw_ABC1234XYz" vercel_blob put README.md
-```
+vercel_storage --json copy <blob url> new/file/path/file.zip
+```
+
+### Delete operation
+
+The delete operation always suceeds, regardless of whether the blob exists or not. It returns a null payload.
+
+```sh
+vercel_storage blob delete <blob url>
+```
+
+## Using vercel_storage in your python code
+
+### Put operation
+
+```python
+from vercel_storage import blob
+
+my_file = '/path/to/file.zip'
+with open(my_file, 'rb') as fp:
+    resp = blob.put(
+        pathname=my_file,
+        body=fp.read()
+    )
+```
+
+`vercel_storage` will look for the `BLOB_READ_WRITE_TOKEN` environment variable. If it is not available
+it will raise an Exception.
+
+If you have the token stored somewhere else, you can pass it directly to the put() function like this:
+
+```python
+  resp = blob.put(
+      pathname=my_file,
+      body=fp.read(),
+      options={'token': 'ABCD123foobar'}
+  )
+```
+
+### Copy operation
+
+```python
+retval = blob.copy(blob_url, to_path)
+# or
+retval = blob.copy(blob_url, to_path, options={"token": "ABCD123foobar"})
+```
+
+### Delete operation
+
+```python
+blob.delete(blob_url)
+# or
+blob.delete(blob_url, options={'token': 'ABCD123foobar'})
+```
+
+### Head operation
+
+```python
+blob.head(blob_url)
+# or
+blob.head(blob_url, options={'token': 'ABCD123foobar'})
+```
