+## Getting started
+
+### Prerequisites
+
+- Go 1.25. See https://go.dev/doc/manage-install
+- node
+- pnpm
+
+### Installation
+
+Add `gitea/custom/conf/app.ini`. See details below for file content. Make sure to properly set `WORK_PATH`.
+
+<details>
+
+```ini
+WORK_PATH = /path/to/forkana ; the only line which needs modification
+
+[server]
+PROTOCOL = http
+DOMAIN = localhost

+EXPLORE_PAGING_DEFAULT_SORT = alphabetically
+```
+
+</details>
+
+Then run
+
+```bash
+$ pnpm install
+```
+
+To build the project:
+
+```bash
+$ TAGS="bindata sqlite sqlite_unlock_notify" make build
+```
+
+Note that it might be necessary, depending on your system's configuration, to prepend a `GO` specification (indicating the name of the executable, if different from just `go`).
+
+```bash
+$ GO=go1.25.2 TAGS="bindata sqlite sqlite_unlock_notify" make build
+```
+
+To run the project:
+
+```bash
+$ TAGS="sqlite sqlite_unlock_notify" make watch
+```
+
+Note that you need to build once in any case, before running continuously with watch.
+
+Finally, visit http://localhost:3000 and you are ready to go to fork with Forkana!
