 A hastebin-compatible paste site running on Cloudflare Workers.
 
+# Deployment
+
+To deploy as a pages project you will need to set up the following:
+
+KV namespace bindings:
+
+- ``STORAGE``: A KV namespace to storage pastes in
+
+Environment variables:
+
+- ``DOCUMENT_KEY_SIZE``: Number of digits to use for document URLs
+- ``MAX_DOCUMENT_SIZE``: Maximum number of characters allowed per paste
+- ``DOCUMENT_EXPIRE_TTL``: Number of seconds until documents expire
+
 # TODO
 
 I did not invest any time into creating my own frontend yet, all static
