+## Search & Displace
+
+## :information_source: About
+
+Search and Displace is developing a workflow and toolchain which intends to address 
+the problem of mass search and displacement for document content where the original 
+documents are in a range of forms, including a wide variety of digital document formats,
+both binary and more modern compressed XML forms, but also encompassing older documents
+where the only surviving form is printed or even handwritten.
+
+## :rocket: Installation
+
+First install nix following the instructions on their website at https://nixos.org/nix/manual/#chap-installation
+
+The add searchanddiplace channel to your nix environment and update it:
+```bash
+nix-channel --add https://github.com/searchanddisplace/searchanddisplace/channel.tar.bz2
+nix-channel --update
+```
+
+You can now install search-and-displace:
+
+nix-env -iA searchanddisplace.default
+
+## :roller_coaster: Usage
