 ## Changing dependency versions
 
-The dependencies are pinned to exact versions in the `requirements_fixed.txt` file.
+The dependencies are pinned to exact versions in the `requirements.txt` file.
 To change this simply change line (approx) 124 in the `Dockerfile` from:
 ```
-    && pip install --no-cache-dir -r "requirements_fixed.txt" \
+    && pip install --no-cache-dir -r "requirements.txt" \
     # && pip install --no-cache-dir -r "requirements_unfixed.txt" \
 ```
 
 to

-    # && pip install --no-cache-dir -r "requirements_fixed.txt" \
+    # && pip install --no-cache-dir -r "requirements.txt" \
     && pip install --no-cache-dir -r "requirements_unfixed.txt" \
 ```
 
 This will install the latest satisfying versions of all dependencies. After testing that
-the dependencies are working freeze them into a new `requirements_fixed.txt` file.

 Several dependencies are installed from source so these must be removed from the
