 ## Troubleshooting
 
-### SSL Verification
-
-You might need to point `openssl` at the location of your certificates **explicitly** to avoid certificate errors on https requests.
-
-```sh
-export SSL_CERT_FILE=/etc/ssl/certs/ca-certificates.crt
-export SSL_CERT_DIR=/etc/ssl/certs
-```
-
-These can be [hardcoded in your Dockerfile](https://docs.docker.com/engine/reference/builder/#env), or you can rely on the [openssl-probe crate](https://crates.io/crates/openssl-probe) to detect the cert location. You should not have to do this if you are using the static variants of `distroless` or `chainguard`.
-
-### Diesel and PQ builds
-
-Works with the older version of libpq we bundle (see [#81](https://github.com/clux/muslrust/issues/81)). See the [test/dieselpgcrate](./test/dieselpgcrate) for specifics.
-
-For stuff like `infer_schema!` to work you need to explicitly pass on `-e DATABASE_URL=$DATABASE_URL` to the `docker run`. It's probably easier to just make `diesel print-schema > src/schema.rs` part of your migration setup though.
-
-Note that diesel compiles with `openssl` statically since `1.34.0`, so you need to include the `openssl` crate **before** `diesel` due to [pq-sys#25](https://github.com/sgrif/pq-sys/issues/25):
-
-```rs
-extern crate openssl;
-#[macro_use] extern crate diesel;
-```
-
-This is true even if you connect without `sslmode=require`.
-
 ### Filesystem permissions on local builds
 
 When building locally, the permissions of the musl parts of the `./target` artifacts dir will be owned by `root` and requires `sudo rm -rf target/` to clear. This is an [intended](https://github.com/clux/muslrust/issues/65) complexity tradeoff with user builds.
