+**Q: error: failed to load manifest for dependency `mesa`**
+
+**A:** 
+
+This is caused because cargo tries to access mesa library code from local filesystem instead of crates.io repository. To fix this, make sure mesa dependency in Cargo.toml looks as below:
+
+```
+
+...
+
+[dependencies]
+# mesa = "0.37.7"
+mesa = { path = "../mesa" } # Only for development purposes
+
+...
+
