+## Requirements 
+
+* Golang 1.19 or higher
+* wkhtmltopdf binary in $PATH (to save pages in pdf)
+
+## Usage
+
+#### 1. Start the server
+
+```shell
+go run ./cmd/server/main.go
+```
+
+#### 2. Add a page
+
+```shell
+curl -X POST --location "http://localhost:5001/pages" \
+    -H "Content-Type: application/json" \
+    -d "{
+          \"url\": \"https://github.com/wkhtmltopdf/wkhtmltopdf/issues/1937\",
+          \"formats\": [
+            \"all\"
+          ]
+        }" | jq .
+```
+
+#### 3. Get the page's info
+
+```shell
+curl -X GET --location "http://localhost:5001/pages/$page_id" | jq .
+```
+where `$page_id` — value of the `id` field from previous command response.
+If `status` field in response is `success` (or `with_errors`) - the `results` field
+will contain all processed formats with ids of the stored files.
+
+#### 4. Open file in browser
+
+```shell
+xdg-open http://localhost:5001/pages/$page_id/file/$file_id
+```
+Where  `$page_id` — value of the `id` field from previous command response, and
+`$file_id` — the id of interesting file.
+
+#### 5. List all stored pages
+
+```shell
+curl -X GET --location "http://localhost:5001/pages" | jq .
+```
+
