+# Niphredil
+
+## Steps to build
+
+* Install Conan>=2
+```
+conda install -c conda-forge conan
+```
+* Create a conan profile
+```
+conan profile detect --force
+```
+* To build the code locally:
+    * Install dependencies with conan
+    ```
+    conan install . --build=missing
+    ```
+    or for the debug version:
+    ```
+    conan install . --build=missing --profile=debug
+    ```
+    * Build with meson
+    ```
+    cd build-realease
+    conan build ..
+    ```
+    or for the debug version:
+    ```
+    cd build-debug
+    conan build .. --profile=debug
+    ```
+* Run the test executable:
+    ```
+    ./meson/niphredil
+    ```
