+### Installation using Conan
+
+1. Install Conan (assuming you have Python and pipx installed):
+
+```bash
+pipx install conan
+conan profile detect
+```
+
+For older versions of pip, you can also use `pip` instead of `pipx`.
+
+2. Build the library:
+
+```bash
+conan build . --build=missing -s compiler.cppstd=gnu20
+```
+
+You can call `conan inspect .` to get an overview of the supported options.
