-# NEXT: v2.1.0
+# v2.1.4
++ added `-Wl,-rpath` argument generation in `link()`. It forces ld to link to local shared library in `OUTDIR`
+
+# v2.1.3
++ added `DEP_OTHER_OUT_FILES` to dependency configs
++ if `PRESERVE_OUT_DIRECTORY_STRUCTURE=true` then `DEP_DYNAMIC_OUT_FILES` and `DEP_OTHER_OUT_FILES` are copied to `OUTDIR` preserving directory structure (example_dir/lib1.so -> $OUTDIR/example_dir/lib1.so)
+
+# v2.1.2
++ changed compile_c and compile_cpp functions
++ bootstrap now can print help and list of installed versions 
+
+# v2.1.1
++ **config**: removed `TESTS_C` and `TESTS_CPP` compilation
+
+# v2.1.0
 + **config**: no more `current.config` and `default.config`, just `project.config`
 + improved version checking
 + `setup.sh` now installs each minor version in separate dicectory
++ added `bootstrap.sh` which automaticly selects cbuild version specified in project config 
 
 # v2.0.2
 + new dependency resolution system (see **config** and `example_dependency_configs`)

-My C/C++ build system written in bash.
+My C/C++ build system written in sh.
 
 
 ## Installation
-```bash
+```sh
-git clone https://timerix.ddns.net:3322/cbuild.git
+git clone https://timerix.ddns.net:3322/Timerix/cbuild.git
 cd cbuild
 sudo ./setup.sh 
 ```
+Can be installed to `~/.local/` if you have no root rights.
+- ```sh
+  ./setup.sh --local
+  ```
+- Then add `~/.local/bin` to `PATH` in your shell config.
 
 ## Usage
 1. Initialize cbuild project in some directory:
-    ```bash
+    ```sh
     cd some_project
     cbuild --new-project
     ```
-
+2. Edit `project.config`.
-2. Edit `default.config`.
 3. Call some tasks:
-    ```bash
+    ```sh
     cbuild build_exec_dbg exec
     ```
+P.S. See help
+```sh
+cbuild -h
+```
