+## Installation
+
+You need [Codon](https://github.com/exaloop/codon) for Seq to work. Assuming that Codon is installed in `$HOME/.codon`, run:
+```bash
+curl -L https://github.com/exaloop/seq/releases/download/v0.11.3/seq-$(uname -s | awk '{print tolower($0)}')-$(uname -m).tar.gz | tar zxvf - -C .codon/lib/codon/plugins
+```
+
+Afterwards, you can use Seq with `-plugin seq`; for example:
+```bash
+codon run -plugin seq test.codon
+```
